- This newsgroup is for discussion of pixmap utilities. A pixmap is
- any image composed of pixels, whether it's a one-bit-deep bitmap, a
- grayscale image, colormapped, or full color. There are dozens of
- different file formats for storing pixmaps, and there are a number of
- software packages for converting between formats and displaying
- formats. Some of these packages are listed in the Frequently Asked
- Questions posting in comp.graphics - the relevant excerpts are appended
- below.
-
- Discussion of these packages and other similar ones will probably be
- the main topic here. Posting uuencoded sample pixmaps for some weird
- format you're trying to decipher is fine, especially if they are small,
- but mass posting of pixmaps is not welcome.

- 7) Free image manipulation software. There are a number of toolkits
- for converting from one image format to another, doing simple image
- manipulations such as size scaling, plus the above-mentioned 24 -> 8,
- color -> gray, gray -> b&w conversions. Here are pointers to some of
- them:
-
- PBMPLUS, by Jef Poskanzer. Comprehensive format conversion and image
- manipulation package. The latest version is always available via
- anonymous FTP as ftp.ee.lbl.gov:pbmplus*.tar.Z,
- wuarchive.wustl.edu:graphics/graphics/packages/pbmplus/pbmplus*.tar.Z,
- and export.lcs.mit.edu:contrib/pbmplus*.tar.Z.
-
- IM Raster Toolkit, by Alan Paeth (awpaeth@watcgl.uwaterloo.ca).
- Provides a portable and efficient format and related toolkit. The
- format is versatile in supporting pixels of arbitrary channels,
- components, and bit precisions while allowing compression and machine
- byte-order independence. The kit contains more than 50 tools with
- extensive support of image manipulation, digital halftoning and format
- conversion. Previously distributed on tape c/o the University of
- Waterloo, an FTP version will appear someday.
-
- Utah RLE Toolkit. Conversion and manipulation package, similar to
- PBMPLUS. Available via FTP as cs.utah.edu:pub/urt-*,
- weedeater.math.yale.edu:pub/urt-*, and freebie.engin.umich.edu:pub/urt-*.
-
- Fuzzy Pixmap Manipulation, by Michael Mauldin <mlm@nl.cs.cmu.edu>.
- Conversion and manipulation package, similar to PBMPLUS. Version 1.0
- available via FTP as nl.cs.cmu.edu:/usr/mlm/ftp/fbm.tar.Z,
- ftp.uu.net:pub/fbm.tar.Z, and ucsd.edu:graphics/fbm.tar.Z.
-
- Img Software Set, by Paul Raveling <raveling@venera.isi.edu>. Reads and
- writes its own image format, displays on an X11 screen, and does some
- image manipulations. Version 1.3 is available via FTP as
- export.lcs.mit.edu:contrib/img_1.3.tar.Z, and
- venera.isi.edu:pub/img_1.3.tar.Z along with a large collection of color
- images.
-
- Xim, The X Image Manipulator, by Philip Thompson, does essential
- interactive displaying, editing, filtering, converting images.
- Available in the X11R4 source tree. A more recent version is available
- via ftp from gis.mit.edu. Requires X11R4 and the OSF/Motif1.1 toolkit
- for the interface. This is not a paint package. Xim reads/writes gif,
- xwd, xbm, tiff, rle, xim, (writes level 2 eps) and other formats. Also
- has a library and command line utilities for building your owm
- applications.
-
- xloadimage, by Jim Frost <madd@std.com>. Reads in images in various
- formats and displays them on an X11 screen. Available via FTP as
- export.lcs.mit.edu:contrib/xloadimage*, and in your nearest comp.sources.x
- archive.
-
- TIFF Software, by Sam Leffler <sam@okeeffe.berkeley.edu>. Nice
- portable library for reading and writing TIFF files, plus a few tools
- for manipulating them and reading other formats. Available via FTP as
- ucbvax.berkeley.edu:pub/tiff/*.tar.Z or ftp.uu.net:graphics/tiff.tar.Z
-
- xtiff, an X11 tool for viewing a TIFF file. It was written to handle
- as many different kinds of TIFF files as possible while remaining
- simple, portable and efficient. xtiff illustrates some common problems
- with building pixmaps and using different visual classes. It is
- distributed as part of Sam Leffler's libtiff package and it is also
- available on export.lcs.mit.edu, ftp.uu.net and comp.sources.x.
- xtiff 2.0 was announced in 4/91; it includes Xlib and Xt versions.
-
- ALV, a Sun-specific image toolkit. Version 2.0.6 posted to
- comp.sources.sun on 11dec89. Also available via email to
- alv-users-request@cs.bris.ac.uk.
-
- popi, an image manipulation language. Version 2.1 posted to
- comp.sources.misc on 12dec89.
-
- ImageMagick, an X11 package for display and interactive manipulation
- of images. Includes tools for image conversion, annotation, compositing,
- animation, and creating montages. ImageMagick can read and write many of
- the more popular image formats. Available via FTP as
- export.lcs.mit.edu:contrib/ImageMagick.tar.Z.
-
- Khoros, a huge (~100 meg) graphical development environment based on
- X11R4. Khoros components include a visual programming language, code
- generators for extending the visual language and adding new application
- packages to the system, an interactive user interface editor, an
- interactive image display package, an extensive library of image and
- signal processing routines, and 2D/3D plotting packages. Available via
- FTP as ftp.eece.unm.edu:pub/khoros/*.
-
- LaboImage, a SunView-based image processing and analysis package. It
- includes more than 200 image manipulation, processing and measurement
- routines, on-line help, plus tools such as an image editor, a color
- table editor and several biomedical utilities. Available via anonymous
- FTP as ftp.ads.com:pub/VISION-LIST-ARCHIVE/SHAREWARE/LaboImage_4.0.tar.Z
-
- The San Diego Supercomputer Center Image Tools, software tools for
- reading, writing, and manipulating raster images. Binaries for some
- machines available via anonymous FTP in sdsc.edu:sdscpub.
-
- The Independent JPEG Group has written a package for reading and
- writing JPEG files. FTP to ftp.uu.net:graphics/jpeg/jpegsrc.v?.tar.Z
-
- Don't forget to set binary mode when you FTP tar files. For you MILNET
- folks who still don't have name servers, the IP addresses are:
-
- ftp.ads.com 128.229.36.25
- cs.utah.edu 128.110.4.21
- export.lcs.mit.edu 18.24.0.12

- Please do *not* post or mail messages saying "I can't FTP, could
- someone mail this to me?" There are a number of automated mail servers
- that will send you things like this in response to a message. See
- item 13 below for details on some.
-
-
- 8) Format documents for GIF, TIFF, IFF, BIFF, WHIFF, etc.
-
- You almost certainly don't need these. Read the above item 7 on free
- image manipulation software. Get one or more of these packages and
- look through them. Chances are excellent that the image converter you
- were going to write is already there. But if you still want one of the
- format documents, many such files are available by anonymous ftp from
- zamenhof.cs.rice.edu (128.42.1.75) in directory pub/graphics.formats.
- These files were collected off the net and are believed to be correct.
- This archive includes pixel formats, and two- and three-dimensional
- object formats. Other file format descriptions are welcome, send to
- Mark Hall <foo@cs.rice.edu>.
-
-
- 13) How to FTP by email.
-
- There are a number of sites that archive the Usenet sources newsgroups
- and make them available via an email query system. You send a message
- to an automated server saying something like "send comp.sources.unix/fbm",
- and a few hours or days later you get the file in the mail.
-
- In addition, there used to be some FTP-by-mail servers, which would accept
- FTP commands by mail and then mail back the results. Unfortunately, the
- services were abused, and have been shut down.
