You maybe can use media-gfx/graphicsmagick or media-gfx/imagemagick for that purpose (I prefer graphicsmagick because it's faster). With the composite command and it's repage parameter it should be possible to do what you want. But I'm not sure about this, I never done this by myself. -- Regards wabe
