Description simon 1998-11-24 17:51:55 UTC
Below I have appended the errors generated by the
ImageMagick module convert. The same errors are generated by
display. I have just installed RH5.2 which uses
ImageMagick-4.1.0. RH5.1 did not generate these errors. Only
Unknown device: pnmraw. I have tested many postscript files
generated from many different softwares, and the result is
the same. What is the cause, and what is the fix for this

Comment 1 Preston Brown 1998-11-24 21:30:59 UTC
this looks like the pnmraw device has to be enabled in ghostscript.
Cristian, you agree with this one?

Comment 2 simon 1998-11-24 22:12:59 UTC
It is not clear to me that pnmraw is the problem, as both RH5.0 and
5.1 versions of gs did not have pnmraw devices. Also the ImageMagick
documentations says it only requires either a pnmraw or ppmraw device.
gs -h shows that ppmraw is available. Also, the first error message
Unknown device: pnmraw was common to both the RH5.0 and 5.1
ImageMagick packages too. Additionally gs used by itself doen't
generate any error messages, which indicates to me that this problem
is probably related to how gs and the ImageMagick modules interact
with each other...

the imagemagick/ghostscript combination that is now in rawhide does
not have problems converting Postscript files to GIF.
