I notice there has been some talk of manipulating Sun icons in sun-spots recently. Here are some programs which can be used to help with this. "editicon" uses "showicon" to convert a Sun icon into a text file containing "#" for black pixels and " " for white pixels. This is then edited using a standard text editor (default "vi"). The text image can be saved using ":w file" or shifted using "s/^/ /", etc., in "vi". On exit from the editor, if the file has been updated, "makeicon" is used to overwrite the Sun icon file. Saved text images can be overlayed together using "over", X-Y axes can be swapped using "swap", etc. Existing Unix tools such as "rev" and "colrm" can also be used to modify text images. As supplied, "editicon", etc assumes 64x64 bit images, but any competent Unix hacker could change this if desired. "ras2icon" is a slightly cleaned up version of "pic2icon", as issued previously on sun-spots (by Jim Meritt?), together with a newly written manual page. I changed the name since "pic" files mean something different at our site. "sun2xicon" and "x2sunicon" convert between SunView and X formats as best they can. I am happy for all these files to be included in the sun-spots archive (assuming the original author of "pic2icon" does not object about "ras2icon"). The files are also available by sending a message such as: send prog editicon.shar to <archive-server@uk.ac.oxford.prg> on JANET or <archive-server@ox-prg.uucp> (...!mcvax!uck!ox-prg!archive-server). However, I would rather US sites obtained copies from the sun-spots archive server to reduce transatlantic traffic. A message of "help" to the archive server will give more information on its use. Here is a list of the relevant files: Name Contents editicon.shar Edit a SunView icon using a text editor (also includes makeicon and showicon) fill.shar Fill text lines to a given column position * over.shar Overlay text files * pos.shar Position lines on given column * ras2icon.shar Convert Sun raster to icon format sun2xicon.shar Convert SunView icon to X bitmap swap.shar Swap rows and columns in a text file * x2sunicon.shar Convert X bitmap to SunView icon All programs are designed for UNIX systems and are shell scripts or C programs (if marked with a *). Some shell scripts may depend on other programs which are not available on all UNIX systems. In particular, these programs have only been tested on BSD4.2 based systems (on Sun-3 hardware). There is no warranty that they will work on your system, but bug reports and updates are welcome. Each ``shar'' file contains at least the following: README Brief description Makefile To make and install files x or x.c Shell script or C program source x.1 Manual page where ``x'' is the name of the program.

It is 86068 bytes in length (if this length poses a problem for you, drop me a line and I will split it into two shar files). It can be retrieved via anonymous FTP from the host "titan.rice.edu" or via the archive server. For more information about the archive server, send a mail message containing the word "help" to the address "archive-server@rice.edu". --wnl ]]

While we're on the subject, some Sun-Spots readers might not be aware of
my "Portable Bitmap" package. This package started the same way as
Jonathan Bowen's, as just a bunch of hacks for converting between bitmap
formats, but I and others have been adding to it for a couple of years
now.
The package was recently posted to the comp.sources.misc newsgroup, so it
should be available from various archive servers. It is also available
via anonymous FTP from expo.lcs.mit.edu (18.72.0.126) as
contrib/pbm.tar.Z.
I have appended the README, but it's pretty long...

Portable Bitmap Toolkit
Version of 12dec88
Previous distribution 31oct88
Included are a number of programs for converting various bitmap formats
to and from a portable format; plus some tools for manipulating the
portable bitmaps.
Changes since the comp.sources.misc distribution of 31oct88:
Added pbmreduce.
Added imgtopbm, tifftopbm, pcxtopbm, and pbmtogo.
Minor bugfix to pbmtolj.
Changes since the X.V11R3 distribution of 31aug88:
The cbm format has been revised to support run-length encoding.
Pbmtops now does run-length encoding.
Major changes since the X.V11R2 distribution of 28mar88:
The pbm format now has a "magic number".
New conversion filters: brushtopbm, giftopbm, pbmtolj, pbmtomacp,
pbmtoxwd, and pbmtox10wd.
Icontopbm converter has a better parser -- it knows to skip over
any extraneous comments at the beginning of the icon file.
Pbmtops generates a different PostScript wrapper program -- it should
handle huge bitmaps better.
Xwdtopbm now handles byte-swapping correctly.
Pbmmake takes a flag to specify the color of the new bitmap.
Pbmpaste now implements 'or', 'and', and 'xor' operations as well
as the default 'replace'.
