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 problem? Thanks --Simon McClusky convert figure2.ps figure2.gif Unknown device: pnmraw Unrecoverable error: undefined in get Operand stack: --nostringval-- --nostringval-- ARGUMENTS --nostringval-- defaultdevice Unexpected interpreter error -21.

this looks like the pnmraw device has to be enabled in ghostscript. Cristian, you agree with this one?
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... --Simon McClusky
the imagemagick/ghostscript combination that is now in rawhide does not have problems converting Postscript files to GIF.
