I’m attempting to use a TexturePeeker to sample a texture, and specifically am using the “filterRect” method in order to cover a range of pixels. As far as I’m aware, the texture being sampled should be valid, as it’s being used elsewhere without trouble.
However, I keep bumping into the following assertion error:
AssertionError: min_y >= 0 && min_y <= _y_size && max_y >= 0 && max_y <= _y_size at line 572 of panda/src/gobj/texturePeeker.cxx
The documentation for “filterRect” indicates that it should wrap the UVs provided to it, so I’m surprised to be hitting what appears to be an issue with the operation overflowing the texture-bounds.
Nevertheless, I’ve tried limiting the extents of the UV-parameters via calls to “min” and “max”–to no avail. Even when limited to values between 0.2 and 0.8 (presuming that I did so correctly), I still encounter that same assertion error.
So, what might be going wrong here…?
