Draw in DrawingCanvas which is not at 0,0?

Hey there!

I have a hard time finding a tutorial or an explanation on how I can draw in the DrawingCanvas object if I moved it, say, in the middle of the screen. Or basically anywhere other than x and y 0.

Expected behaviour: I can just draw in the DrawingCanvas and the pixels will appear exactly where the mouse was.

What actually happens: If the DrawingCanvas is 100x100 big I need to draw in the area inside x<100 and y<100 even though the DrawingCanvas is at 800, 600 or somewhere else. The lines will appear inside the DrawingCanvas though.

How do I convert mouse coordinates to relative DrawingCanvas coordinates?

Thanks in advance!

Set Origin at Top-Left and simply subtract canvas position from mouse coordinates. For example, if canvas is at 200:300, and mouse cursor is at 250:330, draw at 50:30
