How to select a rectangle and zoom to those coordinates

[TomPreuss]

I would like to give the user the ability of selecting a 'hard to read' area on the image by holding down left mouse button and then zooming into that rectangle when the user releases the mouse button.

In 2 lines (the second is optional).

Code: Select all

GdViewer1.MouseMode = ViewerMouseMode.MouseModeAreaZooming
GdViewer1.MouseButtonForMouseMode = MouseButton.MouseButtonLeft
