Version 3.1
=============================================================================

Patchlevel 4 (Aug, 16, 1995)

NOTE 1: The Display PostScript code is not supported anymore until some kind
    user can debug it for me, as I have no access to a server with DPS
    extensions.  Use ghostscript for rendering your EPS files.  It gives
    a color image on the xfig canvas now anyway.

NOTE 2: Because Unisys has stated that they will not charge royalties for the
    use of the LZW compression algorithm in *FREE* programs, xfig will
    continue to support importing and exporting of GIF images.
    However, be aware that if you sell xfig, for example as part of a CD-ROM
    package with freeware, you may be liable for paying royalties to Unisys.
    The authors of xfig and the Lawrence Berkeley National Laboratory cannot
    be held responsible in any case.

NOTE 3: Because of the patent/licensing issue with Unisys and the LZW compression
    algorithm used in GIF files, the author of ghostscript has decided to
    remove GIF support from that program.
    xfig will now use PCX output from ghostscript when importing EPS files.
    This means that you must compile ghostscript with the pcx256 and pbmraw
    drivers.
    Additionally, there is a bug in the pcx driver in Aladdin Ghostscript
    versions prior to 3.32, which writes an incorrect pcx file for images
    with odd width (not even).  There is a compile-time flag set (the
    default) to make xfig add one pixel to the width of an odd-width image
    when it reads in the pcx output from Ghostscript.
    If you have Aladdin Ghostscript 3.32 or newer (which wasn't released
    as of this writing) you may comment out that flag and your images will
    have the proper width.  However, one pixel extra in width shouldn't
    matter for most imported eps files.

NOTE 4: The -textoutline (resource textoutline) option has been moved into the
    -debug option.  This makes xfig draw a red box around text objects for
    debugging purposes.

NEW FEATURES:

o JPEG (JFIF) images can be imported and exported - see Examples/pictures.fig
    Unless you have an image (picture object) in your figure, you may not
    gain very much by exporting in JPEG over GIF because of the nature of
    compression used in both methods.  GIF is usually better for line
    drawings or drawings with large blocks of continuous color (e.g. filled
    polygons).  JPEG is usually better for compressing images.
    The quality factor for exporting JPEG is fixed at 75.  This seems to be
    fine for figures containing only solid objects (no images) and adequate
    for figures containing imported images (GIF, JPEG, etc.).
o New features in the Picture Object edit popup:
    1) Capture a screen image to a GIF file to use for importing.
    2) Call an image editor (e.g. xv) to edit an imported image. New
       resource for the editor: "Fig.image_editor: xv" (default)
    3) Popup a file browser to look for images to import.
    all from Jim Daley ([e-mail])
o the points of arrow heads don't protrude past the endpoints of the object
o when drawing polyline/polygon or spline you can delete newly created points
    by pressing shift-mouse button 1
o when saving figure, original is first renamed to file.bak to make backup file
o smartlinks improved - lines touching boxes inside compound object will be
    moved when compound is moved with smart links mode on
    From Ian Brown
o -help option to print all command-line options to xfig
o can now change boxes to arc-boxes and vice versa with same button that
    converts lines <-> splines.
o label in fill style panel added to separate shaded fill from pattern fill
    (if the pen and fill colors are both black or white it was impossible
    to distinguish the patterns from the 100% shade fill)
o when adding a new user-defined color, it is automatically selected for
    modification without having to click on the cell.
o point positioning now has five resolutions: arbitrary, 1/16" (1mm),
    1/4" (5mm), 1/2" (10mm) and 1" (20mm)
o increased resolution of dimensions in message window when drawing/moving
    objects from 2 to 4 decimal places
o new meta sequence "%f" in print parameters is replaced with current filename
    for printing. Can be used for job name to printer.
    (e.g. lpr ... -J %f ...)
o version/patchlevel added to error handler messages to identify version of xfig
o new export option for MetaFont language
o new resources for ruler and unit box fonts: *topruler.font, *sideruler.font
    and *unitbox.font.  See Fig.ad.
o new resource (Fig.rulerthick:) and command-line arg (-rulerthick) to set
    thickness of rulers (height of top ruler and width of side ruler)
o note about patch for HP compilers in README file (see "Possible problems...")
o on abort, xfig does a cd to the original directory where it was started so
    that any core dump will be in the original directory
o strncasecmp and strcasecmp routines provided for those systems that don't have
    them.  See the Imakefile . From Fred Appelman ([e-mail])

BUG FIXES:

o fig.h includes sys/types.h for BSD and Mips systems and excludes errno,
    sys_nerr and sys_errlist for BSD
    from Kurt J. Lidl ([e-mail])
o error in path for xpm.h in resources.h
o reversed #elif conditions in fig.h for linux/osf defs of random() and srandom()
o text size problem when reading file with text when zoom != 1.0 fixed
o deleted user colors still showed up in color menu in "edit object" panel
o when rotating or flipping an object, the new position wasn't kept on the
    point positioning grid
o selecting drawing mode using keyboard accelerators now updates mouse
    indicator window
o undo of multiple copy (array place) now undos all objects
o undo of "figure load" properly sets "current filename" in File popup and
    "default filename" in Export popup back to original values
o undo of "figure load" does not set "figure modified" flag now
o changing the figure orientation to/from Landscape/Portrait is considered a
    figure modification for quitting/saving
o GIF export was not available if XPM not installed - rearranged order
o misplaced fclose() in f_readeps.c
o misdeclared function close_picfile() in f_readeps.c
o infinite loop when copying a line after scaling a compound using the move
    point mode
o bitmap image of Latex "Italic" font was mis-named "Italics"
o no more hard-wired setting of background for mode and indicator panels
    see Fig-color for more details
o font size for text objects adjusted if < 4 points or > 1000 when reading file
o update settings from object wasn't setting PostScript vs LaTeX flag when Font
    update indicator was enabled
o more checking done in popup edit panel for illegal line thickness or depth
o flip or rotate anchor/center point crosshair turned off when selecting new
    drawing mode
o seg fault in import/edit of picture object due to filename string corruption
o segfault sometimes on file load - gcc sometimes produces code which segfaults
    when doing ungetc on const string. Constant string copied for sscanf
o bug in computing the center of an arc when scaling
o smarter redrawing of objects in correct depth order when creating or modifying
    any object
o changed bestd = ~(((int) 1)<<31); to bestd = INT_MAX in f_neuclrtab.c due to
    temporary integer overflow inside the parentheses
o if -textoutline was specified, boxes appeared around text when exporting to
    bitmap-type format (e.g. GIF, XBM, etc)
o if the file message window popped up before canvas translations were installed
    a warning about the PasteCanv action not being found resulted.  This was
    fixed by narrowing the specification for the translation in the
    app-defaults file.
o bounding box for text objects was incorrect when loading file with zoom != 1.0
o bounding box for ellipses was incorrect with thick lines
o bug in handling text objects with \ at end
    patch from Andrew McParland ([e-mail])
o mis-named character "acute" removed from the multi-key sequence list in man
    pages
o LaTeX font "Modern" changed to correct name "Sans Serif"
    new menu bitmap from Volker Kuhlmann  ([e-mail])
o bounds calculation of objects didn't take line thickness into account
    correctly
o drawing very small arcs (e.g. when zoom is small) resulted in strange lines
    being drawn
o importing XPM images with undefined colors resulted in an X error.  Now xfig
    uses white for null color entries.
o problems with XFree86-3.1.  Get XFree86-3.1.1.
o some picture objects without filenames would be saved incorrectly and
    couldn't be re-read
o extraneous error message about inaccessible file when it contains bad Fig
    object
o bug in bounding box calculation created compound objects off by one unit
o added #include <sys/types.h> for ultrix file stat structure
o bug in scanning 8-bit character followed by a number in text object
    (e.g. \24355 should be the British Pound Sterling character followed
    by 55, not character (octal) 24355)
o in older Fig files (2.1) text at 90 degree angle was slightly jagged due to
    rounding error
o xfig doesn't coredump when delete window operation is done on xfig window or
    user logs out without quitting xfig
o bug in redefining user colors when merging figures
o single-point lines with arrowheads caused segfault - xfig now takes more
    steps to not allow arrowheads for those
o undo of delete arrowhead created arrowhead with current line thickness etc.
    instead of restoring original
o removed extraneous comma (,) from lp command for SYSV/SVR4 systems.
o changed the "-oPS" command-line option (used for SYSV systems) to "-T PS"
    in the Fid.ad app-defaults file.
o typo in FORMAT3.1 file - line and arrowhead thicknesses units are 1/80 inch,
    not Fig units.  Also, dash/dotted size/spacing are in 1/80 inch units.
o some compilers don't like empty .c files (e.g. when XPM is not compiled in)
    static dum_function() placed in f_readxpm.c and f_wrxpm.c for that case
o bug in #include for xpm.h - X11/xpm.h was appended to XPMINCDIR - removed X11/
o added #ifdef ultrix to include <sys/types.h> which is needed for <sys/stat.h>
o black and white colors in colorpanel were set to fore/background colors
    instead of black and white (problem when -bg and/or -fg used)
    from Matthias Braun ([e-mail])
o length of line reported when drawing in Mountain or Mountain/Manhattan mode
    was behind by one point positioning unit until new point was established
-----------------------------------------------------------------------------
Patchlevel 3 (Jan, 24, 1995)

BUG FIXES:

o when using the 3D Athena widgets, user defined color buttons in popup color
    panel were allocating three colors per user color - fix to app-default
    file fixed that (3D widget set was trying to make shadows)
o EPS objects were too small when "Use orig. size" used in edit panel
o hexadecimal color names not parsed correctly for xpm images
o moved include of <stdio.h> and some others above <X11/Xlib.h> for gcc
    warnings about NULL being redefined
o LaTeX text with special flag had wrong style (Roman became Italic etc.)
o cap style implicitly set to ROUND for ellipses and closed splines with
    dotted lines
o some cleanup of pointer/data type casts
    from Randy MacLeod
o incorrect parameter for ibmgl export mode - incorrectly used -L for landscape
o more #ifndef/#endif surrounding random, srandom and frandom in fig.h
o removed the -oPS command-line option for SYSV systems because it is printer
    dependent.  Use the "Fig*job_params*string: -oPS" resource.
o can now dismiss message window while edit panel is up
o command string for printing file too short for some cases - increased

-----------------------------------------------------------------------------
Patchlevel 2 (Jan, 13, 1995)

BUG FIXES:

o ISO8859 restriction on font searching was inadvertantly removed - added back
o hexadecimal color names not parsed correctly xfig standard colors. This was
    causing xfig to switch to monochrome mode after complaining that it
    couldn't allocate the standard colors.
o definition for XCOMM in Imakefile for those running R4
o fixed problem with popup message panel having wrong colors when xfig switches
    to a private colormap
o objects with dotted lines didn't show until an object with dashed line was
    first created
o moved #include of X11/Intrinsic.h to top of fig.h file so
    XtSpecificationRelease would be defined when needed
o comment for patchlevel 1 about command-line option -dontswitchcmap misspelled
o new label in print panel - "Print to PostScript Printer" makes it obvious
    that the only printer type available is PostScript

-----------------------------------------------------------------------------
Patchlevel 1 (Jan, 11, 1995)

BUG FIXES:

o couldn't read eps files that didn't have showpage command
o segfault when non existent eps or other image file is referenced in a figure
o command-line option -dontswitchcmap (resource Fig.Dont_switch_cmap) fixed
o export and file load/merge offsets units (inches, cm, etc) not correctly
    set when -metric option used
o seg fault when converting line to spline because cap_style wasn't initialized
o when converting spline to line, cap_style was set to current cap_style
    instead of style of line being converted

-----------------------------------------------------------------------------
Patchlevel 0 (Jan, 9, 1995)

BUG FIXES:

o NOTE:    An error in version 3.0.0 incorrectly positioned objects on the canvas
    when reading older fig files.  New objects entered with 3.0 are
    correctly positioned.  A warning will popup when you load a version 3.0
    file with version 3.1 that says you might need to offset your figure by
    14 fig units in X and Y when you load it.  This is done by setting the
    X and Y offset in the popup File panel.
    I apologize for the inconvenience.

*****    This is also why the file version number has changed.

o conditionals and macros added for for machines with different random number
    generators
o segfault in show_pen_color and show_fill_color under certain conditions when
    switching colors
o error in x/y load/merge offset when reading pre 3.0 files
o bug in drawing large (6 inches diameter or larger) circles or ellipses with
    dashed or dotted lines and angle of 0 degrees.
o extra line was drawn to center of ellipse or circle when dashed or dotted
    lines used and angle of 0 degrees.
o bug in f_read.c which caused FPE errors when reading incomplete/incorrect
    Fig file
o declaration of count_lines_correctly() inconsistent in f_read.c
o incorrect cast using malloc in f_readxpm.c()
o setcenter, setcenter_x and setcenter_y should be extern in e_flip.c
o setanchor, setanchor_x and setanchor_y should be extern in e_rotate.c
o text following #endif non-ANSI in main.c
o error in source file names in Imakefile - had f_wrgif.o instead of f_wrgif.c
o error in freeing NULL font struct when quitting xfig (in u_free.c)
o renamed basename() to basname() to avoid conflict with Linux libc function
o error in LaTeX font numbering in Doc/FORMATx.x files
o major errors in reading version 1.3 files
o overriding translations in turn_on left black outlines around buttons in
    mode panel when new mode button pressed
o some servers drew black background in indicator panel buttons - caused by
    fill mode being "tiled" for buttons other than the fill style button
o images (GIF, XPM etc) weren't always recolored correctly when using popup
    edit panel on picture object
o DPS fixes for Solaris 2.3
    from Pete A. Zaitcev ([e-mail])

=============================================================================
Version 3.0
=============================================================================

Patchlevel 0 (Dec 22, 1994)
Changes to Version 2.1.8:

NEW FEATURES:

o changes to the file format (protocol).  See Doc/FORMAT3.0 for details.  This
    means you must also get transfig 3.0.  Xfig will still read older Fig
    format files but will always write the new format.

 These are the new features related to the new file format:
-----------------------------------------------------------------------------
   o resolution is increased from 80 ppi to 1200 ppi.  This decreases jaggies.
    A side effect is that xfig can now read fig files of any resolution,
    although it converts the file to 1200ppi internally, and saves it in
    that resolution.
    from Ross Martin ([e-mail])
   o Portrait/Landscape, Print Justification (center or flush left) and Metric/
    Inches indicators saved with figure file now - xfig automatically
    switches to correct mode when reading file
   o separate pen and fill colors for all objects except text.
   o there are now 32 "standard" colors - new ones are: gold, three shades each
    of blue, green, cyan, red, magenta, brown and pink.
   o in addition, there are now user-definable colors which may be defined by
    using RGB (Red, Green, Blue) or HSV (Hue, Saturation, Value) slider bars
    or by hexadecimal values. These are stored in the figure file as pseudo-
    objects of type 0 which define the rgb values in hexadecimal.  The color
    numbers range from 32 to 543.
   o more fill options - colors transition from black to full saturation
    (shades) and on to full white (tints, i.e. pastels).
    Or you can use one of 16 fill patterns - diagonal lines, bricks,
    shingles, crosshatch etc.
   o two arc styles: open (original) and pie-wedge (closed)
   o three line-join styles: miter (default style), round and bevel (see
    PostScript or Xlib reference for description)
   o three line-cap styles: butt (default style), round and projecting (see
    PostScript or Xlib reference for description)
   o three new arrowhead types (both hollow and solid)
    and the tips of the arrowheads are now pointed, as they should be
-----------------------------------------------------------------------------
Features which are independent of the new file format:

o EPS objects have been changed to "picture objects" to include GIF images,
    X11 bitmap images and the XPM3 (color pixmaps) besides Encapsulated
    PostScript.  Compressed (.Z) and gzipped (.z or .gz) files are also
    handled.  Future versions of xfig may include TIFF, etc.  X11 bitmap
    picture objects use the pen color component.  The popup edit panel
    shows the image type, size and number of colors used, if applicable.
    See the Examples/pictures.fig for examples of XPM, XBM and GIF.
    You must have version 3.4c or newer of the XPM library.  This is
    available from ftp.x.org in /contrib/libraries.

    GIF input code from David Koblas' giftoppm code from the pbmplus
    package.

    A Floyd-Steinberg dithering is applied to color images for monochrome
    displays.

    For EPS files, if Ghostscript is used to generate the preview, an 8-bit
    color preview is generated if xfig is running on an color display.
    The command-line option -dSAFER is used when calling ghostscript which
    prevents any files being written by the postscript code.

    The color quantization algorithm to minimize the number of colors
    needed for the color images uses a neural network scheme written by
    Anthony Dekker ([e-mail]).
    [NEUQUANT Neural-Net quantization algorithm by Anthony Dekker, 1994.
    See "Kohonen neural networks for optimal colour quantization"
    in "Network: Computation in Neural Systems" Vol. 5 (1994) pp 351-367.
    for a discussion of the algorithm.]

o when moving an object on the canvas the straight-line (sqrt(x^2 + y^2))
    distance from the original position is reported in the message panel
    along with the X and Y distances.
    from Uwe Bonnes ([e-mail])
o rotate or flip objects around a chosen anchor point - see FLIP and ROTATE
    sections in the man pages.
    from Uwe Bonnes ([e-mail])
o make multiple copies of object as you rotate or copy it - see COPY section in
    the man pages
    from Uwe Bonnes ([e-mail])
o new command panel button to switch canvas between Portrait and Landscape mode
o new option in file load/merge panel to load/merge figure with offset on canvas
o new option to export file with offset on page in inches or cm
o OE and oe characters possible now; though not visible on the canvas because
    they don't exist in the X11 fonts they will print in PostScript
    from Serge Lacourte ([e-mail])
o starting textstep, fillstyle, linewidth and gridmode can all be specified
    with command-line args or resources now (see man pages)
    from Serge Lacourte ([e-mail])
o larger grid (1 inch or 20 mm)
o when zooming very small, number of grid lines are reduced to avoid clutter
o more keys available for multi-key sequence: Alt_L, Alt_R and Escape besided
    the usual Meta key
    from Serge Lacourte ([e-mail])
o in update mode, the control panel doesn't scroll with the indicator buttons
    but stays on the left side all the time
o rulers are a little smarter - fewer labels and ticks when zoom scale is small,
    0.5 inch marks for inches scale when large enough
o minor changes to names of some widgets - "xfig_" prefix removed from those
    having it
o can use "box-scale" on ellipses and circles now besides "scale about center"
o new alignment options - Distribute objects evenly horizontally, vertically
    or both, spacing either their edges or centers evenly, or abutting
    their edges
    from Matthew Leditschke ([e-mail])
o keyboard icon appears in mousefun window when text entry is required
    works during canvas text entry and in ASCII widgets in popups
o carriage return in any ASCII widget in edit popup applies changes
o zoom in and zoom out accelerators (Z (zoomin) and z (zoomout) defaults)
o popup font menu is now two entries wide to reduce overall height
o panning is proportional to zoom factor, i.e. pan step is 1/2 inch in canvas
    units, not drawing units
    from Anthony Smith
o holding down the Shift key while panning pans 5x as far
o fill style indicator shows current color now
o two new Example files: illusion.fig and recycle.fig
    from Vivek Khera ([e-mail])
o four new clip-art files (Examples directory): clp_bldgs.fig, clp_network.fig,
    clp_computer.fig and clipart.fig
    from William J. Chimiak ([e-mail])
o new export languages - GIF and X11 Pixmap (XPM, color X pixmaps) output
    - must have the XPM3 package for XPM output.
    XPM3 code from Karel van Houten ([e-mail])
    GIF code from E. Chernyaev ([e-mail])
o can handle eps files with %%BoundingBox: (atend)
    from Paul Hodgkinson ([e-mail])
o no need for the -DNOSTRTOL flag anymore if your system doesn't have strtol()
o export magnification factor added for X11 bitmap/pixmap output
o MAXNUMPTS (the maximum number of points displayed for large objects) may be
    specified in the Imakefile with -DMAXNUMPTS=xxxx, if desired

BUG FIXES:

o first/opposite corner designation for box objects was reversed in popup edit
o line count correct when reporting any errors reading figure file
    from Andreas Bagge ([e-mail])
o when scaling box object, size of box now shown with first click when using
    middle button
o more sanity checks on starting values (e.g. -startfillstyle < 0 etc)
o changes in dot/dash spacing were sometimes delayed in effect.  Fixed.
o if printer name came from env variable, it didn't show up in print panel until
    first figure was printed
o smarter redraw of underlying objects when updating or rotating objects or
    moving, adding or deleting points of an object
o metric scale is now correct size when printing
    from Hans Werner Strube ([e-mail])
o temporary file for importing EPS objects wasn't honoring XFIGTMPDIR
o text angle was written with only 5 decimal places - causes rounding errors
o after adding/deleting a point from a poly object, copying a compound object
    would cause xfig to hang (loop in linked list)
o grid wasn't reset when changing to/from Imperial/Metric scale
o "Ruler units" message was incorrect when changing to/from Imperial/Metric
o file_msg() routine now uses varargs
    old method was causing crashes to occur on a 64 bit machine
o toggle of update masks wasn't using correct variable
o when drawing a dotted line with only two points which are coincident, some
    servers die and others give BadLength error.  A call to draw a point
    is substituted in this case.
o bug in changing directory using ".." in text panel for "Curent Directory" in
    file and export popups
o in monochrome mode, popup color choice panel black/white reversed from
    indicator button for blue-yellow
o first section of man pages didn't mention IBM-GL language in reference to
    fig2dev
o filled objects didn't show the fill pattern in monochrome mode
o seg fault when xfig used default font when desired font could not be found
o fixed some memory hog problems with accelerators
o some typos in the class names of bold/normal/button fonts in man pages
o double clicking on a filename to load it sometimes resulted in garbage or
    blank filename in file name panel.
o remnants of #ifndef NO_SIBGUS (note typo) fixed.  NOW there is no need for
    #define NO_SIGBUS if your system doesn't have SIGBUS.  Automatic now.
o typo in fig.h check for #ifdef(SYS) instead #ifdef(SYSV).
o added check for SCO3.2r4 which needs stdlib.h for atof() and getenv()
o switching between LaTeX and PostScript fonts while entering text object
    caused illegal font to be created in text object
o GC's tr_gc, tr_xor_gc, tr_erase_gc, sr_gc, sr_xor_gc and tr_erase_gc declared
    in resources.c and in w_rulers.c
o cur_cursor set to arrow_cursor before arrow_cursor was created
o experimental color definitions in resources in main.c clobbered variables
    because array wasn't large enough.
o false query about overwriting existing fig file fixed
o shifted keyboard accelerators work with caps lock besides shift key
o text bounds fixed
o smarter text locator when moving rotated text
o missing "return 1" in bitmapDPS procedure (Display PostScript machines)

    XRotPaintAlignedString()
o bug in memory allocation for font name when desired font doesn't exist
o increased memory allocation for large, rotated ellipses

=============================================================================
Version 2.1
=============================================================================

Patchlevel 8 (Oct 1, 1993)
Changes to Patchlevel 7:

NEW FEATURES:

o minimum movement for mountain/manhatten mode reduced from 7 pixels to 2
o lengths/radii of objects now displayed on first click in move point mode, not
    just when actually moving the points
o -DOPENWIN no longer necessary - xfig automatically first uses OpenWindows
    scalable fonts (e.g. times-roman-33) if they are available, X11R5
    scalable fonts next if they are available or non-scaling fonts if
    neither of the above is available.
o maximum radius of arc-boxes increased from 30 to 100 pixels
o icon now shows current filename (without full path)
o Control-L does Redraw when not in text input mode (same as Meta-R)
o popup query to shift whole figure when reading in figure file if any objects
    have negative coordinates
o mouse function window shows pan/zoom operations when control key is pressed
o popup query when exporting figure if figure has not been saved (note: this
    is not necessary for exporting current figure but is a warning to
    the user that the figure hasn't been saved yet)
o BSD-style printing on SYSV machines (like SGI) allowed by setting -DBSDLPR
    in Imakefile/Makefile
    from Dave Goldberg ([e-mail])
o on-screen rotation of text at any angle
    xfig now uses xvertext 5.0 from Alan Richardson which allows rotation
    at any angle. The whole font is not loaded anymore, and strings are
    cached, which speeds up the interactive input of text.
o man pages no longer use .TS (table) commands for those systems whose roff
    doesn't support tables.  Also formatting cleaned up and typos fixed.
    From David W. Sanderson ([e-mail])
o double click on filename in File menu will automatically load figure
o double click on filename in Export menu will automatically export figure
o some more information about text objects has been added to the Doc/FORMAT2.1
    file - specificly about the font and font_flags fields
o keyboard accelerators for drawing/editing mode panel.  See Fig.ad for details
    From Tim MacKenzie ([e-mail])
o Example figure which contains building blocks for making flowcharts - called
    flowchart.fig in the Examples directory (replaces old flowchart.fig)
    from Tim P. Starrin ([e-mail])
o The default is now for xfig to use X11R5 scalable fonts unless the server
    doesn't support them.  The user may still disable them with -noscalable
    or the resource "Fig*scalablefonts: false".
o new button panel in the indicator panel to set/clear or toggle update flags to
    make it easier to control which object attributes are affected by update
o new command-line paramter: -but_per_row (resource But_per_row) specifies the
    number of buttons wide the mode panel should be.  This is useful in
    conjunction with -pheight for small screens to reduce the canvas area.
o no need to add -DNO_SIGBUS to Imakefile for systems without SIGBUS anymore.
    This this is automatic now.

BUG FIXES:

o changing a filled object to unfilled now draws background correctly
o cleaned up inconsistencies with fill colors in monochrome mode
o GC's were being freed twice if window quit was executed (window manager)
o exporting figure to X11 bitmap only exported visible part of canvas
o current directory wasn't set in export popup unless file menu had been popped
    up previously
o units box didn't change from "in" to "cm" or vice versa when changing from
    Imperial to/from Metric
o editing text with popup edit at zoomscale != 1 shows correct text size now
o undo of text delete at another zoomscale shows correct text size now
o colons (:) removed from widget names (difficult to set resources with colons)
o conditional definition of index = strchr (or strchr = index) for those systems
    which already have them defined
o workaround for linux bug where certain 8-bit characters are not read properly
    by sscanf()
    from Alain Lucien Knaff ([e-mail])
o height of cursor for text input closer to actual text height (was "descent+
    ascent" tall, now is "ascent" tall)
o <Meta>L (LoadFile function) didn't query if current figure was modified before
    re-loading file
o if normalFont can't be loaded, "fixed" font is tried - if that fails xfig
    quits with error message
o 8-bit character did not appear on canvas
o semicolon missing from "for" statement in main.c
o caused core dump if the environment variable PRINTER was not set and the
    Fig*printer*string was not set
o -startfontsize parameter wasn't being honored
o quit() function was being called with too few parameters.  This kills xfig
    on OpenWindows servers.
    From David Partain ([e-mail])
o fixed bug with freeing two identical GC's (caused coredump when quitting on
    certain machines)
o fixed bug inadvertently introduced in 2.1.7 which caused some arcs to be drawn
    as circles
o scaling of arc inside compound no longer produces co-linear points
o messages didn't appear in the message panel when filename panel wasn't
    large enough
o parameter missing from call to curve() which made strange half-ellipse for box
    curve radius indicator. Caused massive problems for OpenWindows servers.
o moved two accelerators (SaveFile and LoadFile) from top-level to the File
    widget heirarchy (this was causing OpenWindows servers to eat memory)
o work around for bug in OpenWindows 2.0 with bitmaps in widgets (caused
    BadMatch error when popping up the print panel)
o duplicate .TP in xfig.man caused nroff to throw away the text following the
    "Dismiss" description in the print section
o emptyname() dereferenced null pointer if printer name was NULL
o malloc didn't alloc enough space for fontname + null in w_drawprim.c
o text outline box was sometimes drawn incorrectly
o Renamed ICONFIGFILES (already used by X11 config) to ICONXFIGFILES and defined
    it in Imakefile (it was referenced but undefined)

------------------------------------------------------------------------------
Patchlevel 7 (May 3, 1993)
Changes to Patchlevel 6:

NEW FEATURES:

o Vertical and upside-down text - text with angles of 90, 180 and 270 degrees
    supported. Text between those angles will be drawn with the next
    higher angle (e.g. 130 degree text will be drawn at 180 degrees).
    from Alan Richardson ([e-mail])
o message panel uses asciiTextWidget so one may select text from it
o does not ask if it is OK to write an existing file during save if it is the
    current figure file that is being saved.  Same for export.
o accelerators to Save or Load file without popping up file menu
    (default: Meta-S to Save and Meta-L to Load)
o PRINTER environment variable is used if no resource is set for
    Fig*printer*string
o if an ellipse is scaled such that the radii become equal it is "converted"
    to a circle

    mouse button 3 in the units box (where rulers meet)
    from Paul King ([e-mail])
o new command-line parameters -userscale (resource userscale) and -userunit
    (resource userunit) which are used in the on-screen messages which
    show the current length/diameter etc.  This provides a simple way of
    doing scale drawings, e.g. 0.25 inch = 1 ft (userscale=0.25,
    userunit="ft") or 1 cm = 1 m (userscale=1, userunit="m").  These may
    be changed via the popup menu by hitting mouse button 3 in the units
    box (where rulers meet)
o new indicator button allows text flags to be viewed/set
o compiles/runs on DEC Alpha with OSF/1 now
o text widget in the print popup to pass extra parameters to print program
    (lp or lpr as the case may be)
o indicator shows the number of figures in the batch print file in print popup
o automatic on-screen generation of preview bitmap for EPS objects if you have
    gs (ghostscript) - compile with -DGSBIT flag
    from Michael C. Grant ([e-mail])
    adapted from
    Marc Goldburg's ([e-mail]) original idea and code.
o indicator in upper-left corner (under Quit button) shows current filename
o print button changes message from "print FIGURE to printer" to "print BATCH to
    printer" if there are figures in batch file
o when drawing objects or moving/adding points the length/radius/diameter is
    displayed in the message window
o feature to shift figure on page if it is off the page has been disabled until
    it can be done with option or explicit command
o added -noscalablefonts command-line option to force scalable fonts OFF
    (usually for debugging)

BUG FIXES:

o condition for OSF/1 added to use dirent
    from Dave Hill ([e-mail])
o Floating point values allowed for BoundingBox in EPS files
o if user asks for scalable fonts but server doesn't support them, xfig auto-
    matically switches to non-scalable fonts
o when printing to batch file, incorrect filename appeared in message panel
o undo of a text move didn't redraw the text
o <unistd.h> included unnecessarily in f_util.c (X11/Xos.h includes it if
    necessary). Also, various cleanups with multiply defined cursors etc.
    From Casey Leedom ([e-mail])
o internalborderwidth resource should be integer not float
o cancel when drawing latex line left unwanted garbage on screen
o put_fmsg removed and put_msg uses varargs now so MIPS machines and others
    should all work fine now
o writing X11 bitmap still had bugs
o text wasn't being rotated around mouse point with rotate mode
o when moving end points of a (sp)line or when adding points to the end
  of a (sp)line, the angle geometry button was not available
o export directory now follows file directory when load/save figure is done
o entering centered text with odd number of characters caused double image
o fixed bug with incorrectly placing text with point positioning on when the
    text was originally created with point positioning off
o when moving centered or right-justified zoomed text grab point was shifted
o rotated ellipses panned incorrectly
o centering/flush-left options in Export menu were reversed
o flipped EPS objects weren't being flipped properly when reading in figure
o GC's weren't being freed when xfig finished
o added Titan OS (Stardent) to list of machines needing getenv() and atof()
    explicitely defined (not in /usr/include/... file )
    from Joachim Wiesel ([e-mail])
o underscores weren't showing in text line in popup edit
    from Daniel Faigin ([e-mail])
o old text outline wasn't being erased
    from Daniel Faigin ([e-mail])
o number[] array wasn't large enough for new 3-character numbers in the rulers
    from Andrew Haylett ([e-mail])
o check for X_NOT_STDC_ENV reversed in fig.h for inclusion of stdlib.h and
    defs of getenv() and atof()
    from Jonathan Kamens ([e-mail])
o SetDir() parameters added (but not used) to placate certain compilers
o point positioning resolution wasn't available with add-point-in-object
o angle geometry indicator appeared when moving/adding points but isn't used
o problem fixed with file popup and grab
    from David Brooke ([e-mail])

------------------------------------------------------------------------------

NEW FEATURES:

o support for two button mouse - use META + Button 3 to simulate button 2
    from Lars Berntzon ([e-mail])
o new resource "textoutline" (class "TextOutline") and command-line argument
    "-textoutline" which will outline text in red to show the bounding box
    that the text will occupy when printed (useful for rotated text)
o print popup stays up until dismissed - can still pop up file/export menues,
    draw etc. while print popup is up.  HOWEVER, while file or export
    popups are up, the print panel is not active.
o can align all objects to canvas, not just to compound - use mouse button 2
    idea from Jon Forrest
o ellipses may now be rotated by an arbitrary angle and show their rotation
    from Janes Tough ([e-mail])
o new -iconGeometry command-line argument
o new command-line argument and resource -exportLanguage to specify default
    Export language.  See man pages.

    popup panels and top command panel accelerators; <Meta>f will popup file
    panel, <Meta>q will quit, etc. See resource file and man pages for
    details.
o one may now batch together several xfig files for printing with one print job.
    See popup print panel and man pages.
o new label in the mouse function window & more obvious default color (yellow)

o more cleanup with respect to procedure/variable types/casts
    from Don Sharp ([e-mail])
o fixed text bounds calculation to take into account any rotation when reading
    in figure from a file to decide whether to shift figure to keep on
    canvas
    (fig2dev 2.1.5 is also fixed so figures with rotated text near edges
    should center properly now)
o fixed bug where segments disappeared while drawing interpolated spline in any
    LaTeX drawing mode
o rearranged a-z and A-Z keys in the CompKeyDB file because some HP computers
    were apparently doing random things with capitalization
    from Anthony Shipman ([e-mail])
o fixed export of color figure to X11 bitmap format.  White -> white, all other
    colors -> black.
o removed apparently unnecessary translation from w_export, w_file and w_print
    which causes coredump on some HP machines.
    From Alfred van der Hoeven ([e-mail])
o fixed initialization bug in u_undo.c and object.c which caused HP 9000/700
    compilers to segfault
    From Alfred van der Hoeven ([e-mail])
o new environvemt variable "XFIGTMPDIR" used for xfig temporary files directory
o when reading a figure file, if any object coordinates are negative, the figure
    is shifted to keep it on the canvas so that the upper-left corner of the
    figure is placed on the current point positioning grid
    (in 2.1.4, the upper-left corner was placed at 10,10)
o changed "char" to "unsigned char" for initialization of bitmaps by compilers
    from Teus Hagen ([e-mail])
o was passing floats to put_fmsg() instead of doubles.
o includes copy of X11/Xfuncs.h now to use correct routines for zeroing/copying
    memory.

    CompKeyDB (multi-key) database file in the standard X11 library
o fixed bug introduced in 2.1.1 which incorrectly placed radius marker of
    circles created by radius
o circle is now changed to ellipse type when scaled assymetrically
o fixed various typos in xfig.man
o changed references to mouse buttons left/middle/right to say buttons 1/2/3
    respectively
o radius of ellipses-specified-by-radius was one pixel too large
o changed interpretation of 1/0 bits in EPS preview bitmaps back to original
    0=white, 1=black according to EPSF guide version 2.0.
    Brought to my attention by Vivek Khera ([e-mail])

Changes to Patchlevel 3:

o keyFile resource allows ANY path for compose key data base, not just relative
    to $XFIGLIBDIR
    from Pete Kaiser ([e-mail])
o simple edit arrowhead feature in the popup edit for lines - can add/delete
    arrow heads.  No adjustment of arrow size yet - uses current linewidth
    from indicator panel
o Example figure files have all been converted to 2.1 file format
o if any object coordinates are negative, the whole figure is shifted to keep it
    on the canvas
o fixed major bug where the preview bitmap of EPS objects was in reverse video
    (1 is white not black, according to the PostScript Language Ref. Manual)
    *** SEE COMMENT IN PATCHLEVEL 5 ABOUT EPSI PREVIEW BITMAPS ***
o general cleanup of param types in Xt callback/action etc. procedures and other
    lint cleanup

    up respective menus used incorrect options
o changes to the file popup:
    o new "Home" button changes directory to $HOME
    o ~ (username) operator allowed in the current directory ascii widget
    o new label widget shows the current figure filename
    o presssing "Load", "Save" or "Merge Read" will operate on the
      filename in the "Filename" window.  If that name is empty the
      operation is done on the file specified in the "Current Filename"
      window.
    o additionally, the "Load" operation will copy the name (if any)
      from the "Filename" window to the "Current Filename" window
    o pressing return in the "list of files" window in the popup File panel
      will "Load" the file
o changes to the export popup:
    o new "Home" button changes directory to $HOME
    o ~ (username) operator allowed in the current directory ascii widget
    o pressing return in the "list of files" window in the popup Export
      panel will "Export" the file

    the screen)
o If you have Display Postscript in your server, compile xfig with -DDPS
    and you will see the full Postscript object instead of preview bitmap
    when you include EPS objects.
    !!! WARNING: this has only been tested on IBM's AIX 3.2 (X11R4) on
    an RS/6000 !!!
    from Dave Hale ([e-mail])
o fixed bug in error return from system() - now popups error message when
    can't export/print figure
o unused function clear_char_string() deleted from w_canvas.c
o current depth is now in an indicator window and may be set like line
    thickness, color etc.
o added update tags to control which object components are modified/copied
    when using the update button.  Button appears in upper-right corner
    of indicator button (e.g linewidth) when in update mode.  Clicking
    on the update tag enables/disables components (e.g. linewidth) from
    being copied to/from objects when using update.
o fixed exporting of pstex_t and pstex (used to give Postscript for both)
o FIG 1.4-TFX file area_fill values now correctly translated to 2.1 format

    from Dave Hale ([e-mail])

------------------------------------------------------------------------------
Patchlevel 3 (Jan 1992)
Changes to Patchlevel 2:

o pressing carriage return in value part of popup indicator buttons that take
    integer or float (e.g. line width) now sets the value and pops down
o added foreground colors to Text*, Menu* and List* widgets in default Fig-color.ad
    this fixes problem of white-on-white text when using inverse video

    "xfig_export_menu.export_panel.just_label.justify"
    and
    "xfig_print_menu.print_panel.just_label.flush left" to

    From Herve Soulard ([e-mail])
o popup message window to inform user when illegal values in figure file
    are fixed or when converting from older file versions to newest
o limit on depth of objects to 1000 when reading figure file. Fixes problems
    of infinite looping for files which were converted from Fig 2.0.
    Also sets depth to zero (0) when reading files older than 2.1.
o xfig.man now tells man to run tbl so that regular tables can be used
    from James B. Davis ([e-mail])
o fixed Meta-Y (insert current selection), ^Y (unkill) and ^G (multiply reset)
    in CompKeyDB
o added capability to delete whole text line from text widgets with ^X
    from Brian Boyter (pyrdc!bimbo![e-mail])

    from David Elliot ([e-mail])

------------------------------------------------------------------------------
Patchlevel 2 (Dec 1991)
Changes to Patchlevel 1:

o the font flag (LaTeX, PostScript) wasn't being changed correctly in the
    UPDATE text object operation when switching from LaTeX to PostScript
    or vice versa.
o the textstep value may now be entered in floating point in the popup menu
o the eps-bitmap icon was renamed to eps-object because it can be any
    eps object that is imported.  If it has a preview bitmap
    that will be displayed.  Several filenames/program variables
    were also changed to reflect this.
o there is now a more general glue mechanism for compounding objects
o text pasting into canvas now possible with F18 function key or any translation
    desired by user.  F18 is hardwired default in program; F20 also
    programmed in Fig.ad to paste text.
    Brian Boyter (pyrdc!bimbo![e-mail])
o DEFAULT fill_style caused core dump
    from Jeffry R. Abramson ([e-mail])
o made the mouse-tracking markers hollow so as not to be visually obtrusive
    as suggested by Stephen Gildea ([e-mail])
o removed extraneous call to free() in add_point() (u_draw.c)
    from Per Fogelstr|m ([e-mail])
o cleaned up gcc compiler warnings about type mismatches etc.
o compound objects may be rotated by arbitrary angles if there are no boxes,
    arc-boxes, ellipses or circles contained within.
o text rotation support is improved - markers are now shown rotated and
    the angle attribute is set by the relevant rotate operations.
o both ps and eps modes now supported in export menu.
o new directory browsing facilities integrated with File and Export popups.
    Allows selection of file by clicking on the filename.  Has mask to list
    only those files of interest.  See the man pages for further details.
o Default font for Postscript fonts may now be selected and objects that
    have default font may be edited
o FASTSERVER flag removed; now always uses smart redrawing when available
    Additionally, smart redrawing is available more often
o fixed bug in regular polygon where some vertices were off by one pixel
o added "Use orig. size" button for eps objects to set object to original
    size in popup edit
    from Peter Scott ([e-mail])
o international characters supported (umlauts, accents, cedilla etc) using
    compose (meta) key
    from Herve Soulard ([e-mail])
o much improved color support
    from Henning Spruth ([e-mail])
o additional pan and zoom mode with <Ctrl>Key and left/middle/right button
    from Henning Spruth ([e-mail])
o removed reference to FONTLIBDIR in Imakefile (no longer required)
o added a smart-links feature for the MOVE and COPY commands.
    With smart links turned on, when a BOX-like object is moved
    so are the lines which join up to it (its links).
    Two modes are supported: one which moves just the endpoint,
    the other slides the endlink so that it's angle doesn't change.
    In the second mode horizontal/vertical lines remain that way.
o added the ability to save figure during quit if it is modified
o added support for scalable fonts under R5
o additional command line flags supported
    -latexfonts flag (resource .latexfonts) to start xfig with the LaTeX
    fonts as the default instead of PostScript fonts
    -specialtext flag (resource .specialtext) to start xfig with special
    text as the default
o bug fixed where number of objects count in file popup was sometimes clipped
------------------------------------------------------------------------------

Patchlevel 1 (Oct 1991)
Changes to Patchlevel 0:

o xfig now reads text size, height and length as floats and rounds to ints
    this is done because certain programs generate floats for these
o compound object was rounded to next larger grid even if objects inside were
    already on the grid
o Examples/logo.fig included Logo.eps instead of logo.eps
o cancellation of line drawing left single dot on screen
o filename in File popup menu didn't get set until first popup - file save
    shortcut would save to unnamed.fig even if xfig was started with file name
o bug fixed in not being able to delete points from certain objects
o typo in FORMAT2.1 file (and all previous) stating that text angle is int when
    it is really float
o can now change corners of compound object with edit popup
    also shows number of objects inside compound
o file menu now shows number of objects in figure
o some bugs fixed in calculating bounding boxes after scaling ellipses and

o "#ifdefined SYSV" now reads "#if defined(SYSV) || defined(SVR4)" because X11R5
    doesn't define SYSV if SVR4 is defined

o object depths < 0 are converted to depth = 0
o typo in Adobe font name (was "-abode-new century schoolbook-medium-r-*--*")
    Jan Lindheim ([e-mail])
o radius field for non-arcbox line objects now set to -1
    Jan Nusteling ([e-mail])
o bug fixed in not trying to load an eps bitmap file called <empty>
    and not trying to reload an eps bitmap during a copy.
o bug fixed which caused crash after editing 0-width or 0-height ellipses
o bug fixed which caused incorrect mode after cancelling draw (int)spline
o bug fixed which caused incorrect minimum number of points for (int)spline
o bug fixed which caused erroneous large values to occur after box scale of
    0-width or 0-height objects.  You can no longer box scale such objects

Patchlevel 0 (Sep 1991)
Changes to Version 2.0 Patchlevel 10:

Implemented by Paul King ([e-mail]) and
Brian Smith ([e-mail]) with help from
Micah Beck ([e-mail]) and
Brian Boyter (pyrdc!bimbo![e-mail]) (EPS code).

USER INTERFACE
--------------

o The buttons are now grouped into three panels:

    COMMAND panel:
        Quit, Delete all, Undo, Redraw, Paste, File popup, Export popup and
        Print popup buttons.  See man pages for details.
        (see "Drawing Modes", below for description of Cut)
    MODE panel:
    Allow the user to select the current drawing or editing mode.
    INDICATOR panel:
    By default shows indicator buttons relevant to the current mode.
    Each indicator button displays current setting of some quantity
    (e.g. line width, area-fill) and allows it to be changed:
        left button gives popup menu to select setting,
        middle/right buttons provide a shortcut to inc/decrement settings.

o Pan figure by using left/middle/right button in the rulers in addition to
    the previously supported arrow keys.  Also a pan to origin operation
    is available by clicking in the units window (or using HOME key).
o May now print figure that hasn't been saved (i.e. print what is on the
    canvas, not the file)
o Zoom up or down with zoom button.
o Mouse function window shows function of active buttons
o New resources/command-line switches which affect the user interface:
    -showallbuttons        (show all indicator buttons all the time)
    -internalBW n        (use lines of width n between buttons/panels)

DRAWING MODES
-------------

o Regular polygon drawing button - select number of sized from bottom panel.
        Object created is normal xfig polygon.
o Inclusion of Encapsulated Postscript files (bitmap image in EPS file is
    displayed).
o Rubberbanding of ellipses/circles.
o Filled splines show areafill on screen now
        also dashed/dotted line type shows on screen
o Dot-gap and dash-length can be changed in the line-style indicator popup.

EDITING MODES
-------------

o Cut to buffer operation is now part of Copy object mode & Delete object mode.
o Update button to either update objects to current settings, or update
        indicator settings from an object.
o Rotation of certain objects by any angle (30, 45, 60, 90, 120 degrees can
    be selected using the mouse middle/right shortcut buttons).
o Alignment horizontally and/or vertically of objects to compound object edge(s)
o Objects can be scaled (not just compounds).
o Point move or object copy/move constrainable to horizontal or vertical
    movement (middle mouse button)
o Compound bounding corners shrink to fit enclosed objects and have markers
    that appear the same as other objects.
o Shift-click selection should work on all editing operations.
o Only the objects relevant to a particular editing operation will
    have their markers shown.

OVERALL OPERATION
-----------------

o Smarter redrawing (if compiled with -DFASTSERVER).
    Only the relevant objects are redrawn after an expose or after
    an edit operation (not all operations support this yet).
o Undo should work for all commands.
o Operations can now be cancelled (using the right button when appropriate).
o Point positioning to three resolutions:
    magnet (1/16inch), small grid or large grid
o TransFig 2.1 features: LaTex fonts, hidden text, scalable text, "special" text
        see TransFig man pages for description
        scalable text sizes with resizing of figure
o Attempts to save figure if signal detected (segmentation violation, etc)
o Resizing the xfig window should now be a bit smarter.
o The philosophy behind button usage has changed. This was necessary to
    provide a consistent (as possible) philosophy which supports the
    use of several buttons per mode.  Now the same button used to start
    an edit/draw operation is used to continue to the normal next step
    in the operation.  The right button can be used to cancel an operation.
    Watch the mouse function window until you get the hang of it.
