Does the Overlay Bitmap allow pixels to be colorized on a per pixel basis?

Hello,

the method OverlayBitmap.GetGraphics returns an object representing the overlay bitmap as a GDI+ drawing surface. This allows pixels to be manipulated.

Does the returned GDI+ object use the Windows Coordinate system of Top/Lef or does it use the ImageControl Coordinate system of Bottom/Left?

Hello,

it uses the top left system. You may have a look in the "Creating an Overlay" sample that comes with IC Imaging Control .
