By scrolling the mouse wheel, you can change the size of the picture. To do this, press the right mouse button and select a marker. If you compile my code, you can display two kinds of markers - "shield" and "dot". I use layers to render small "markers" to the screen. Tried RBLayer.Scaled: = False It doesn't work for me. In Graphics32, I need to completely disable the RubberbandLayer of the eraser.
