public final class ImageSequenceDataSourceextends QTObjectimplements QuickTimeLib
QuickTime 2.1 introduced support for an arbitrary number of sources of data
for an image sequence. This functionality forms the basis for dynamically
modifying parameters to a decompressor. It also allows for codecs to act as
special effects components, providing filtering and transition type effects. A
client can attach an arbitrary number of additional inputs to the codec. It is up
to the particular codec to determine whether to use each input and how to
interpret the input. For example, an 8-bit gray image could be interpreted as a
blend mask or as a replacement for one of the RGB data planes.

Creates a new data source for an ImageSequence.
Method Summary
void
changedSourceData()
Notifies the compressor that the image source data has changed.
