BufferPainter::Fill(Image,...) optimization question [message #53749]

Hi Mirek,

After getting inspired by the recent improvements in DrawImage(), I tested the BufferPainter::Fill(Image,...) using images with both kind=IMAGE_OPAQUE and kind=IMAGE_ALPHA. It seems they apparently render at the same speed. Is there any room for "easy" optimization when rendering opaque images?

(I really tried to look for the code where the rendering is actually done, but BufferPainter is way too complex for me to navigate... Confused

Confused

Maybe you could point out the file and line where the decision between opaque rendering and alpha blending is actually done.)

Best regards,

Tom
