Hi all,
does anyone have an idea how to determine the transparent (indexed) color of an gif image usin gd? It's necessary since gd does not support gif manipulation, only readin. Therefore in one of my projects i wanna allow the upload of gifs whiche are automatically converted to pngs - however, it would be nice if i could keep existing transparencies. Sure, i can set them via ImageColorTransparent, but first I gotta determine which color is actually the transparent one. So does anyone have any ideas/experiences with that problem?
Thx in advance
