Image::setPixelData and Alpha Channel!


#1

Hi Jucers

I am experiencing trouble with the Image::setPixelData function:

  • I have a Graphics obj initialized with an Image to draw on. The Image is initialized with transparentwhite Colour so only the regions where I draw on, are really written.
  • Drawing the Image on Screen is completely - the transparent pixels are also shown transparent
  • Problem: when I try to “mix” the pixels of the upper Image with another Image by setting

the result is filled with white colour whereit should be transparent so i don’t see the second image at all.

Is there some trick?

Thx a lot!

Nina
