|

*
|
|
* @GST_JPEG2000_SAMPLING_NONE: no sampling
|

|
|
* @GST_JPEG2000_SAMPLING_RGBA: standard Red, Green, Blue, Alpha color space.
|
|
* @GST_JPEG2000_SAMPLING_BGRA: standard Blue, Green, Red, Alpha color space.
|
|
* @GST_JPEG2000_SAMPLING_YCbCr-4:4:4: standard YCbCr color space; no subsampling.
|
|
* @GST_JPEG2000_SAMPLING_YCbCr-4:2:2: standard YCbCr color space; Cb and Cr are subsampled horizontally by 1/2.
|
|
* @GST_JPEG2000_SAMPLING_YCbCr-4:2:0: standard YCbCr color space; Cb and Cr are subsampled horizontally and vertically by 1/2.

* @GST_JPEG2000_SAMPLING_GRAYSCALE: basically, a single component image of just multilevels of grey.
|
|
* @GST_JPEG2000_SAMPLING_YBRA4444_EXT: standard YCbCr color space, alpha channel, no subsampling,
