mH

Contains a reference to a media handler. You obtain this reference from the GetMediaHandler function, which is described on page 2-265.

graphicsMode

Contains a pointer to a long integer. The media handler returns the graphics mode currently in use by the media handler. This is a QuickDraw transfer mode value.

opColor

Contains a pointer to an RGB color structure. The Movie Toolbox returns the color currently in use by the media handler. This is the blend value for blends and the transparent color for transparent operations. The Movie Toolbox supplies this value to QuickDraw when you draw in addPin, subPin, blend, or transparent mode.
