I want to copy the frame of a movie that has alpha channel to an ofImage keeping the alpha transparency. My code looks something like this:
img.draw(0,0); // has no alpha -- debugger says it's RGB, not RGBA
movie.draw(0,0); // has alpha alright and it is transparent
In the log I found these errors:
[ error ] ofImage: getBmpFromPixels(): unable to get FIBITMAP from ofPixels
[ error ] ofImage: putBmpIntoPixels(): unable to set ofPixels from FIBITMAP
Any hints on how to make it work?
