wait a minute. I forgot to say that I don't even need the transparency feature of the Image class. I only use Image - as I said - because of Image[x, y] pixel access. For the meantime - or as a final solution? there may be a lot of those accesses and I thought using Image[x, y] will be the most efficient way to go - I switch to using an 8*8px Picture and Draw.Pixel() instead but I would really appreciate anyone clarify this topic to me. ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
