Input Transformations

An input transformation maps the coordinate space of the magnified screen content to the actual (unmagnified) screen coordinate space. This mapping ensures that pen and touch input in magnified screen content is mapped to the appropriate coordinates of the unmagnified screen. The following functions were added to support input transformations.

Topic Description
MagGetInputTransform

The following function was added to enable showing or hiding the system cursor.
