I’ve a problem with Image transparency. I have several components superposed, every one with a background with a dynamic opacity and a foreground completely opaque. In order to optimize paint function, I would like to use for every component an offscreen image updated only when needed. I’ve tried with a juce Image, but if I draw an image with a transparent or semi-transparent background in top of the others (using drawImageAt), the result is a black background.
How do that?
Many thanks for any suggestion
