Thank you for the demo.
When this AV should occurs?

There is no AV. The picture looses its bottom scanline. That is a (small) problem.

I see and understand now, thanks.
I have researched it, the reason of this situation is in the stretching procedure. Size of the image is greatly reduced and some pixels are lost. Were tested standard GDI stretch procedure, GDI+ procedure and own stretching procedures. Last line was cropped in all cases. I haven’t idea how to improve it now, maybe make source image smaller…

Thanks.
I think I have to make the source image a bit LARGER with transparent pixels at the bottom.

@AlphaSkin, have you tried to play with InterpolationMode in Gdi+ ?

I made the original pictures 260×260, although the max is 256×256. It solved the problem.
Please, close this topic.
