Actually I am porting a Windows .NET software to GTK. So some procedure I use (as false color convertion) is written. I will use it as is because it's not depending on GTK or else... Anyway... First I create a color structure wich define 256 different color from cold to hot. Then I convert my 16 bits image to a 8 bit and for each pixels value I replace with the corresponding color. It's help a lot for understanding a picture. I also add a conversion scale (for example to convert only values between from 100 to 256) I can post the code used, but _for the moment_ it still use .NET and FreeImage library, but algorythm remains the same _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
