[comp.graphics] color GIF to TIFF converter wanted

kusumoto@chsun1.uchicago.edu (Bob Kusumoto) (07/02/90)

Are there any PD or Shareware (or even commercial for that matter) programs
out there that will convert color GIFs to TIFF or some other format.  pbm
doesn't seem to handle color GIFs so is there an update to the GIF->pbm
program or is there another route to take here?

Please email/post if such a program is available, I'm also looking for one.

Hello,

 I posted a similar question and found what appears to be the right package
for doing the conversion on a PC.  Get the file grafwk31.zip from the simtel20
or wuarchive msdos graphics sub-directory and take a look.

FBM 1.0 handles color GIF <-> TIFF.

    TIFF formats handled
	Input/	1,2,4,8, or 24 bit files, with or without colormap.
	Output	Colormaps are truncated from 3x16bits per color to
		3x8bits per color.

	Does not handle PLANAR_CONFIG_SEPARATE format RGB files, though.

    GIF formats handled
	all GIFs from 2 to 256 colors.

Machines

    Runs on most 32bit Unix boxes.  Vax, Sun, NeXT, IBM RT.

    Is known to have problems with the color quantization code
    (routine fbquant) on Cray XMP under UNICOS.
