GXLoadTransform

You can use the GXLoadTransform function to load a transform into memory.

void GXLoadTransform(gxTransform target);

target

A reference to the transform object to be loaded into memory.

DESCRIPTION

The GXLoadTransform function moves a transform object from disk storage to the active graphics client heap of your application. When you or QuickDraw GX unload a transform object from memory to disk storage using the GXUnloadTransform function, QuickDraw GX creates a 4-byte stub that remains in the graphics client heap. When you use the GXLoadTransform function to retrieve the stored object, QuickDraw GX obtains the location of the stored transform object from the stub.
