Magnifier

Magnifier is a frame at the right-bottom corner of in LiteCAD graphics window (see the picture below). It displays enlarged area of a drawing which is currently under cursor. As user moves a cursor over a drawing, image in the magnifier is being changed accordingly, in real-time.

In the LiteCAD.exe program you can on/off magnifier by menu "View / Magnifier", in your application - by setting LC_PROP_WND_MAGNIFIER property.
When magnifier is active, you can position cursor over the magnifier frame and click right mouse button to call popup menu where you can change some properties.
