magnify screen

To help a person with visual impairments, I need to zoom in (approx 200-500%) on an area of the desktop, or another application (e.g. Word). I also need to pan up, down, left or right at this magnification.

Any examples or API function would be much appreciated.

Do you need to program it yourself? If not, there is a tool called ZoomIn (which is shipped with Visual Studio) that does exactly what you specified.

In terms of API, the StretchBlt function can be used to redraw an image with different dimensions.

That's the basis of a ZoomIn program.
