It would appear that the Alpha channel of a PNG image is reversed in the vertical direction.
When using ilOverlayImage(overImage, 0,0,0), the alpha mask is upside down in the resulting image. Scaling the image before applying works as expected: the alpha is still upside down.
This is using the WIn32 1.6.5
My PNG images are 720x480, RGB with Alpha.
Anyone else experiencing this?
I'm just starting to get involved with the source here but don't have a much time to work on this but if you want to send me some test code and a test image i'll try and have a look this weekend.
