Thanks for the links. BeRoPNG seems to load a PNG and the author states it’s fast and has no external dependancies. Fantastic.

According to Reimar’s code the raw image data is sufficient for glTexImage2D so I wonder if the data pointer returned from BeRoPNG would work also?

In my Apple CoreGraphics code I was drawing the image into a bitmap context and getting pixel data from the bitmap but that seems to be an extra step now.
