I have been looking at what you have suggested but I don't see how it can help me. If we are drawing directly to Paint(Upp::Draw& w) which is where we get the speed boost, but then we switch back to ImageBuffer which does not have any function its self to draw lines and rectangle and other things. Then I looked at the Image utility functions and I also don't see any functions that allow drawing lines I only see rectangles, so I am not seeing anyway to do this with out some sort of Painter.
I have tried PaintingPainter, BufferPainter, ImagePainter, DrawingDraw and then used PaintImageBuffer to get that into the ImageBuffer and it is all slow, like 5 FPS.
So I am not sure how to do everything I need. The main Application Has Rectangles, Rectangles with Dashes, Lines, Lines with Dashes, Images, an overlay with transparency and scaling when zoomed in and out with ctrl + scroll wheel.
I figured out the dashes and rectangles and lines but the scaling and overlay with Draw is not possible and the only option after that is to render everything into a ImageBuffer and all the methods I have seen are really slow.

Best regards,
