This topic summarizes the changes that were made to the Magnification API for Windows 8. The following sections describe the changes:

Full-Screen Magnifiers

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.

TopicDescription

MagGetInputTransform

Retrieves the current input transformation.

MagSetInputTransform

Updated Magnifier Sample Application

The magnifier sample application was updated to demonstrate the full-screen and cursor hiding capabilities of the new API functions. For more information, see Magnification API Sample.
