Allows the application and Source to identify which color data formats are available. There are two options,
"planar" and "chunky".
Remarks:
For example, planar RGB data is transferred with the entire red plane of data first, followed by the entire green plane, followed by the entire blue plane (typical for three-pass scanners).
"Chunky" mode repetitively interlaces a pixel from each plane until all the data is transferred (R-G-B-R-G-B…) (typical for one-pass scanners).
