Hello again,

Did anyone observe the same behavior on Linux Red Hat 5.3 with the export to GIF files (see email below)? I tested on other operating systems :

-        GMSH 2.5.0 on RedHat 5.3 : does not work, GIF file is actually a PNG file

-        GMSH 2.6.0 on RedHat 5.3 : gmsh did not start because of a missing dynamic library libgfortran.so.3 (I tried with a library found on a Ubuntu 64bit machine but apparently, this version requires a 32bits library, which I don't have)

-        GMSH 2.4.2 on Ubuntu 10.4 64 bits : ok, works fine, GIF file is correct

-        GMSH 2.5.0 on Windows 7 64 bits : ok, works fine, GIF file is correct
Thank you in advance for your help,
Christophe Henrard

Subject: Print to GIF


I'm using GMSH version 2.5.0 on Linux. I'm developing scripts to post-process computation results. If I manually save a figure as a GIF file, everything is correct. However, if I do it in my script using the following syntax :
               Print Sprintf(FigName);
               FigName = "/my/path/myfig.gif";
The figure name of the file written on disk is correct but the file format is PNG. Does the "Print" function only exports as PNG or am I missing an optional argument or something?
Using version 2.5.0 on Windows does not show this behavior, only Linux.
Thank you for your help.
Kind regards,
Christophe Henrard
