GD Transparency


The Little Guy

Recommended Posts

I am working with the GD Library, and I was wondering if anyone knew of a function or a way to set the transparency of a GD image (Not the final image)

 

What I am doing is taking an jpg image as the bottom image, then I would like to place a jpg image on top of it with 50 transparency, then flatten the image as a jpg.

 

I can not find anything on this, only information on setting png alpha values.
