Parameters
graphicContext
Graphic context on which to draw.
zoomX
Horizontal zooming factor. By default, true scale is used.
zoomY
Vertical zooming factor. If set to
panX
Horizontal panning value expressed in pixels. By default, no panning occurs.
panY
Vertical panning value expressed in pixels. By default, no panning occurs.
drawDiagonals
Specifies whether or not lines are to be drawn between the 1st and 3rd corners, as well as between the 2nd and 4th corners.
color
The color in which to draw the overlay.
Remarks
Drawing is done in the device context associated to the desired window.
Deprecation notice: All methods taking HDC as parameter are deprecated. It is recommended to use their alternative taking a EDrawAdapter by using a instance of EWindowsDrawAdapter.EQuadrangle.Draw
