typedef enum WICJpegYCrCbSubsamplingOption {
WICJpegYCrCbSubsamplingDefault = 0,
WICJpegYCrCbSubsampling420 = 0x1,
WICJpegYCrCbSubsampling422 = 0x2,
WICJpegYCrCbSubsampling444 = 0x3,
WICJpegYCrCbSubsampling440 = 0x4,
WICJPEGYCRCBSUBSAMPLING_FORCE_DWORD = 0x7fffffff
} ;
Constants
WICJpegYCrCbSubsamplingDefault Value: 0 The default subsampling option. |
WICJpegYCrCbSubsampling420 Value: 0x1 Subsampling option that uses both horizontal and vertical decimation. |
WICJpegYCrCbSubsampling422 Value: 0x2 Subsampling option that uses horizontal decimation . |
WICJpegYCrCbSubsampling444 Value: 0x3 Subsampling option that uses no decimation. |
WICJpegYCrCbSubsampling440 Value: 0x4 Subsampling option that uses 2x vertical downsampling only. This option is only available in Windows 8.1 and later. |
WICJPEGYCRCBSUBSAMPLING_FORCE_DWORD Value: 0x7fffffff |
