Hello,

I have the OpenDX Cygwin 4.1.1 version working well with Win98 and I
have some troubles with the ReadImage and WriteImage modules when trying
other image formats than "rgb". Imposible to read "tiff" format and to
write "gif" format.

I made a search on the mailing list with "Readimage" and "tiff" but this
could not help me. May I have missed a library when installing OpenDX ?
( I have not downloaded the ImageMagick libraries ). Here is a
description of my tests :

1. ReadImage test :

I tried the very simple example ReadImage.net with the "colorado.tiff"
image and I got this error :

ERROR : ReadImage : Invalid Data :
C standard library call, read(), returns error

I ckecked the "colorado.tiff" image with Corel Photo-Paint and it is OK.
No problem with Readimage.net when trying to read "rgb" images from the
samples/data directory or written from my own net.

2. WriteImage test (or Save Image from the File menu of the Image
window) :

I can save images, in "rgb", "tiff" or "miff" format, but the DX server
crashes when I try to write "gif" format. The saved "tiff" image cannot
be read by Photo-Paint (error message : "Missing directory entry").

Thank you in advance for your help.
