Hi all I'm planning to write an export plugin for gimp for my 3d engine in order to make a 2d interface: It have to keep the layer and add some info (for example: "this is a text-layer, ref xxxx" and my engine will put the string that it want on this layer. My first idea is too export each layer in a separate png file (I would like to have lightweight files) and to write a text file which would contain the name of the png file, the size of the pic and the coordinates of this pic. What do you think of this idea? how would you proceed? Where can I find some source code which do similar things? Thx Mandor
