Dynamically drawing a transparent bitmap

1) use TBitmap do draw on the canvas, this makes it really easy 2) set it to transparent 3) define the transparent color (if you forget this, the color of the pixel in the bottom left corner will be used): var myBitmap : TBitmap; //.. begin // somehow create myBitmap myBitmap.Transparent := true; myBitmap.TransparentColor := clBlack; end;
