[Gmsh] Question on generating geometries and meshes from JPEG files

[David Colignon]

Save the text of the script as, for example, script.geo on your desktop. Put also your image file (image.jpg) on your 
desktop. Use notepad.exe to edit script.geo and replace the third line

Merge "cg.jpg";

by

Merge "image.jpg";


Save the edited script, launch gmsh.exe, and open the script.

Dave
