[fpc-pascal] Does FCL Image support transparency?

Hi, I want to put watermarks on images in a command line application. This doesn't do the trick: ScaledImage:=TFPCompactImgRGBA8Bit.Create(Width, Height); Canvas:=TFPImageCanvas.Create(ScaledImage); // TFPImageCanvas Canvas.StretchDraw(0,0,Width,Height,Image); // Image is TFPCompactImgRGB8Bit Ca
