- Display 39.11 (c) Copyright 1990-1993 Commodore-Amiga, Inc.
-
-
- Display is a program for displaying IFF ILBM format image files.
- V39.x Display supports V39 and 8-bit-per-gun AA graphic modes, but still
- runs under 1.3 and 2.0 as long as iffparse.library is present.
- (2.04 Workbench's iffparse.library will run under 1.3.)
-
- The Display program can display single pictures, or can present a keyboard,
- mouse, or automatically advanced slide show. Display can also be used
- to print ILBM graphics.
-
- Under 2.0 and higher, Display supports overscan screens centered based
- on the user's Preferences, autoscroll screens, and explicit modeid for
- display if desired.
-
-

-
- Displaying a single ILBM file
- =============================
-
- From CLI:
-
- Display filename [opt [mlbpaenvf][t=n][d=x]] (options explained later)
-
- From Workbench:
-
- either Use the left mouse button to click on (select) the Display
- icon, then shift/double-click the ILBM picture file icon.
-
- or single click the ILBM picture file icon then select the
- Workbench Icon menu "Information" item. Enter Display as the
- Default Tool in the Information requester and Save.
- Now double-clicking that ILBM picture icon will automatically
- load the Display program and display the picture.
-
- Closing the display:
-
- By default, clicking in the upper left corner or using CTRL-C
- will close the display. Other options described later allow mouse
- advance, looping, and automatically timed displays.
-
-
-
-
- Displaying multiple ILBM picture files as a "slide show"
- ========================================================
-
- Display has the ability to do a slide show. There are several methods
- for doing a slide show. Some are more useful for on-the-fly situations,
- and others are more suitable for planned presentations.
-
-
- From CLI: (options explained later)
-
- either Display filename filename [filename [filename...]] [opt options]
-
- or Display from filelist [opt options]
- where filelist is a file which contains an ASCII text list
- of the ILBM filenames you want to display. A filelist file
- can be created with any plain ASCII text editor such as
- Ed or Memacs. The contents of an example filelist follows
- (assuming you have a directory called Pictures containing
- some ILBM graphic files):
-
- Work:Pictures/MonaLisa
- Work:Pictures/Max
- Work:Pictures/NewYork
-
- Certain per-picture options may also be specified on each
- line of a filelist (see Options section later).
-
- From Workbench:
-
- either Single-click on Display, then shift-click the pictures you
- wish to display, shift-double-clicking on the last picture.
-
- or Set up a slideshow file as follows:
- Create a text filelist as described above and place
- the file in a directory accessible from Workbench.
- Create a "Project" type icon for the file and save the Project
- icon in the same directory as your filelist file, giving
- it the same name as your filelist but with ".info" added
- to the name. Then select your Project icon (you may have
- to Update the window first) then select Information from
- the Workbench Icon menu. Enter Display as the Default Tool,
- and add the following tooltype: FILELIST=TRUE
- Also read about the additional Tooltype options below.
- You may wish to add some like MOUSE=TRUE (for a mouse-advanced
- show) or LOOP=TRUE and TIMER=seconds for an automatic show.
-
-
- Advancing the display:
-
- By default, you must click in the upper left corner or CTRL-C to
- advance from one displayed picture to the next. However, with simple
- options suchas MOUSE (m), LOOP (l), and TIMER (t), described in #3 below,
- you can advance and back up using the mouse, and create automatic looping
- timed displays. CTRL-D will terminate an entire slide show and exit
- Display.
-
-
-
- Options
- =======
-
- From CLI, Display options are specified after the filename(s) by using
- the "opt" keyword followed by your options.
-
- Example: Display mypicture opt m
-
- In addition, certain options may be specified on a per-picture basis in
- a text filelist for Display.
-
- From Workbench, options are specified as ToolTypes in the icons of the
- Display program, or the ILBM file icons, or in the icon of a filelist.
- ToolTypes are entered using the "Information" selection in Workbench's
- "Icon" menu. (Single click an icon, then select the Workbench menu item).
-
-
- CLI Workbench Description
- === ========= ===========
-
- FROM filelist FILELIST=TRUE Display the pictures LISTED
- in the text filelist file
- attached to this icon
- (one picture and optional
- options listed per line)
-
- m MOUSE=TRUE Left mouse button advances
- slideshow, right goes backwards
-
- mm MMOUSE=TRUE Left mouse button advances
- slideshow, even if one one
- picture is being shown
- (i.e. click on picture and
- it goes away)
-
- l LOOP=TRUE Rather than exiting after the
- last picture, loop back to
- the first picture.
-
- b BACK=TRUE Causes pictures to remain as
- the back screen, unactivated.
- Useful when printing pictures
- while working.
-
- a AUTOSCROLL=TRUE If picture is bigger than
- visible display clip, enable
- autoscrolling - i.e. automatic
- scrolling when mouse reaches
- edge of visible display
-
- p PRINT=TRUE Cause Display to automatically
- print each picture that is
- displayed. Note that you can
- also print manually by pressing
- CTRL-P.
-
- e EHB=TRUE Treat unspecified (no CAMG)
- 6-bitplane pictures as Extra
- Halfbrite rather than HAM.
-
- n NOTRANSB=TRUE A 2.0 and ECS option. Causes
- borders to NOT be transparent
- when genlocked.
-
- v VIDEO=TRUE A 2.0 and ECS option. Causes
- picture to be displayed with
- full-video display clip.
-
- f BESTFIT=TRUE Ignore CAMG modeid if any
- and instead let OS decide
- best modeid to display in.
-
- s NOMONITOR Crudely strips monitor ID
- if any from CAMG
-
- r NOCENTER If picture is larger than Max
- Overscan for mode, will place
- upper left corner of screen
- at upper left corner of display
- clip (rather than centering
- screen around display clip.
-
- d=hhhhhhhh DISPLAYMODE=hhhhhhhh Ignore CAMG mode id if any
- and instead display using
- this mode id (where hhhhhhhh
- is hex mode id with no 0x or $)
-
- t=seconds TIMER=seconds For automatic advance when
- time elapses.
-
-
- The following options may be specified on a per-picture basis in
- a picture icon or in a line of a filelist:
-
- CLI opt Tooltype
- ======= ========
- e EHB=TRUE
- n NOTRANSB=TRUE
- v VIDEO=TRUE
- a AUTOSCROLL=TRUE
- f BESTFIT=TRUE
- s NOMONITOR=TRUE
- r NOCENTER=TRUE
- d=hhhhhhhh DISPLAYMODE=hhhhhhhh
-
- Most other options are global and may only be specified on a CLI
- command line, or in the Display icon, or in a filelist Project icon.
-
-
-
- Examples
- ========
-
- - Print three files as a background task:
-
- run Display file1 file2 file3 opt bp t=1
-
-
- - Display a list of files as a looping (l) slide show, showing each picture
- for 5 seconds:
-
- Display from myshow opt l t=5
-
- where the text file "myshow" contains:
-
- path/mypicture1
- path/mypicture2 opt a d=00008004 (extra options for this picture)
- path/mypicture3
-
- - Start a mouse-advance slideshow for a presentation
-
- Display from myshow opt ml
-
-
- Note - if you put a project icon on the file "myshow", set its
- Default Tool to Display, and enter the tooltypes MOUSE=TRUE and
- LOOP=TRUE, you could start the same slide show by double-clicking
- the Project icon.
