[Lazarus] Layered TFPImage

[Leonardo M. Ramé]

Hi, I need to create two or three TFPMemoryImages as a kind of "layers",
then flatten all layers into another TFPImage.

I can copy one image onto another, by copying its pixels, but this way
the background image is covered by the upper image, because its
background is not transparent.

What I need is a way to copy one image WITH TRANSPARENT BACKGROUND onto
another.

Regards,
