A new version of my image conversion / manipulation package is now
ready.
The beta-test version released on 13sep89 brought in a fair number of
bug reports, so this version should be pretty solid. Also, I've made
some improvements in the area of handling extremely large files:
ppmscale, pnmcat, and pnmflip all operate line-by-line now, instead of
reading in the whole image. This is mostly the result of one night
spent playing with a 4100x4100 grayscale image of the moon.
Aside from that, the big changes are:
tifftopbm became tifftopgm, because it now handles grayscale. It
also handles both byte orders now.
The PostScript and X bitmap converters go three times as fast.
Added picttopbm.
g3topbm now works, thanks to Paul Haeberli, plus he added pbmtog3.
The Sun rasterfile converters will now compile on non-Suns, and
no longer have byte-order problems.
See the CHANGES file for a more complete list.
I've sent shar files off to the comp.sources.misc moderator. They will
probably show up pretty soon, he tends to give quick turnaround.
For those on the Internet, the package is available via FTP as:
expo.lcs.mit.edu:contrib/pbmplus.tar.Z
ftp.ee.lbl.gov:pbmplus.tar.Z
For the MILNET folks who still don't have name servers, the IP addresses
are:
expo.lcs.mit.edu 18.30.0.212
ftp.ee.lbl.gov 128.3.254.68
Don't forget to set binary mode when you retrieve it, and please don't
FTP during working hours (9 am to 6 pm). This version will probably
also show up in the X.V11R4 release -- I'm pretty sure I met all their
requirements.
I have appended a list of all the formats currently supported. Enjoy.
