[Gmsh] Print a Correct GIF Picture

[Uwe Blechard]

Hi Gmsh group,

I have a problem with the correct figure of a GIF file. Sometimes the 
picture has a wrong skaling or it shows only a part of the whole model
(if you want, I can attache an example).

The situation is:

- I have a skript file to display the results of a FEM calculation
  in Gmsh
- after that, I scale the size of the Gmsh window by
    General.GraphicsHeight
    General.GraphicsWidth
- after that two last command, I started a print command to write a GIF 
  picture
- afterwards I scale the picture again with an other scale value and
  print it to an other GIF file

Often I get a wrong GIF picture, which shows a part of the model or
strips and pixel and so on. Unfortunately this problem is not
reproducible. Sometimes all is right and sometimes not.

I used some option in my batch file (f.e. Draw; BoundingBox;
Sleep; General.FastRedraw = 0; General.DoubleBuffer = 0;) 
to solve this problem. Nothing solves the problem really.

Question: Have you got some ideas, some proposal, some
command parameter, which I can tested and solve the problem.

I tested this behavior on a UNIX HP and also on LINUX with
1.60.

Thanx for your help.

Best regards,
Uwe Blechard
