I have a picture in compressed TIFF format and also in Macintosh PICT format. And I want to transfer it into sun raster format. Does anyone know of any program that can transfer one of the two format into raster format? Editor's Note: There are quite a few rasterfile manipulation routines in the sun-source archives at Rice (titan.rice.edu) which you might want to look at, notably one (paintraster.c) changes from a Macpaint file into a Sun rasterfile. I don't see anything that does a TIFF to Rasterfile conversion, though I am fairly certain that such a thing exists.

The current version supports many more formats, including color formats, has many bug fixes, runs much faster, etc. b) The place to get up-to-date information about this package, other graphics interchange packages, plus lots of other interesting things, is the Usenet newsgroup comp.graphics. If you don't get Usenet, you should. But at the very least, if the sun-spots moderator is going to pass along graphics queries, then he should read comp.graphics so that he can answer the easy ones (like this one) himself. {Ed's Note: Moderator already reads too many newsgroups as it is, remember, I'm working with 24 hour days here :) } c) I already get far too much mail, most of it stupid, about this software. I do not appreciate people posting very partial info and then saying "mail jef for more". In an attempt to fend off some of the mail that will surely result from Neil's message, I have appended an excerpt from the "Frequently Asked Questions" message in comp.graphics.

There are a number of free toolkits for doing image format conversions, simple image manipulations such as size scaling, plus the above-mentioned 24 -> 8, color -> gray, gray -> b&w conversions. Here are pointers to three of them: Utah RLE Toolkit. Available via FTP on cs.utah.edu. Fuzzy Pixmap Manipulation, by Michael Mauldin. Version 0.9 was posted to comp.sources.unix, and is available from c.s.u archives. The latest version is always available via FTP in nl.cs.cmu.edu:/usr/mlm/ftp. PBMPLUS, by Jef Poskanzer. Version of 13sep89 was posted to alt.sources. The latest version is always available via FTP as expo.lcs.mit.edu:contrib/pbmplus.tar.Z. Don't forget to set binary mode when you FTP tar files.
