In a few days I'll post an update to ImageLibEx than can handle pixel level alpha. At the moment it supports constant alpha blend by the BitmapEx method.
AlphaBlend(src, srcrectangle, percent, destleft, desttop, transparent, transcolor)
where percent is the alpha for the source bitmap. I'll be adding
AlphaPixelBlend(src, srcrectangle, alphadata, destleft, desttop, transparent, transcolor)
where alphadata is a bitmap containing the alpha for source each pixel. It will need to be read from a file created on the desktop from a png file by a new Alpha object in the library. Full details will be in the help.
