Input type

A 32-bit integer that specifies the type of data that is to be received from the secondary data source.

Overview

Valid values for this field are as follows.

Input identifier	Value	Description
`kTrackModifierTypeMatrix`	1	A 3 × 3 transformation matrix to transform the track’s location, scaling, and so on.
`kTrackModifierTypeClip`	2	A QuickDraw clipping region to change the track’s shape.
`kTrackModifierTypeVolume`	3	An 8.8 fixed-point value indicating the relative sound volume. This is used for fading the volume.
`kTrackModifierTypeBalance`	4	A 16-bit integer indicating the sound balance level. This is used for panning the sound location.
`kTrackModifierTypeGraphicsMode`	5	A graphics mode record (32-bit integer indicating graphics mode, followed by an RGB color) to modify the track’s graphics mode for visual fades.
`kTrackModifierObjectMatrix`	6	A 3 × 3 transformation matrix to transform an object within the track’s location, scaling, and so on.
`kTrackModifierObjectGraphicsMode`	7	A graphics mode record (32-bit integer indicating graphics mode, followed by an RGB color) to modify an object within the track’s graphics mode for visual fades.
`kTrackModifierTypeImage`	`'vide’`	Compressed image data for an object within the track. Note that this was `kTrackModifierTypeSpriteImage`.
