// NOTE(inso): how to use:
|
|
//
|
|
// load up the icon in gimp and choose export, select "c source code (*.c)" as the format
|
|
// call the file gimp_icon.c, then include it by uncommenting line below.
|
|
//
|
|
// make sure the struct in the .c file is called gimp_image (the default).
|
|
//
|
|
// then just compile and run this program and it'll create linux_icon.h
