Hi
I have two sprites that are overlayed, both saved as png images. The top one has transparencies which I have set using the alpha channel in the image file. The transparency should be 0% or 100%, there are no semi-transparent parts of the image. However, I am getting a greyish border around my upper image. I have turned off antialiasing in my image software, and I've also tried using the black parts as the transparent bits, and the image is only black and white. However the grey border remains. Am I doing something wrong?
Thanks.
