PNGs with a height > 2048 crash TGB

When I try to load PNG with a height larger than 2048 I can an error message but TGB crashes afterwards. JPGs > 2048 work.

I believe the deal is that most video cards have a limit on the size of textures allowed. TGB can handle more than that, it's just that your video card can't. I would strongly suggest against using any textures greater than 2048.

I think that all (semi) modern video cards support at least 4096 Textures but this was not my point. My point is that the reader seems to not support PNG sizes > 2048. The JPG loader does and an image that is bigger than 2048 is displayed properly when loaded as JPG.

I seem to recall a hard coded limit/check for max 2048 in the png code.

The Frame Allocator is used in bitmapPng.cc for temporary memory. Try increasing the size of the frame allocator (I think it's 3mb, by default) to allow larger PNGs to be loaded and processed.
