On my proper unix/linux systems I do a lot of imaging work with .ppm.gz or .ppm.bz2 files (binary 'P6' PPM, not the 'P3' ASCII version). The ImageMagick utilities (e.g display, convert) understand this format and it works well. However, with Cygwin, having created an image.ppm.bz2 or image.ppm.gz2 file display image.ppm.bz2 exhibits some corruption of the image, but bunzip2 image.ppm.bz2 ; display image.ppm works fine (as does display image.ppm.bz2 of the file on a linux box). It looks suspiciously like the sort of corruption you'd get from binary/text filemode confusion, but setting CYGWIN=binmode or accessing the files by a binary mount makes no difference. The problem isn't limited to display e.g convert image.ppm.bz2 image.jpg ; display image.jpg or convert image.ppm.bz2 image.xbm ; xsetroot -bitmap image.xbm both show corruption. I've attached the result of a cygcheck -s -v -r > cygcheck.txt and one of the problem image.ppm.bz2 files. If this is a bug, hope this is useful info. If not, what am I doing wrong ??
