VDXPixmapFormat enumeration
The VDXPixmapFormat enumeration is used to indicate bitfield and color
space encoding for pixels.
| Null | Invalid, unspecified, or default format. |
| XRGB1555 | 16-bit RGB, 5 bits per sample, RGB bitfield ordering |
| RGB565 | 16-bit RGB, 5 bits per red/blue sample, 6 bits per green sample, RGB bitfield ordering |
| RGB888 | 24-bit RGB, 8 bits per sample, BGR byte ordering |
| XRGB8888 | 32-bit RGB, 8 bits per sample, BGR byte ordering followed by unused byte |
| Y8 | Luma-only (grayscale) encoding, with luma range according to BT.601 |
| YUV422_UYVY | 4:2:2 YCbCr interleaved encoding (half horizontal chroma resolution), Cb/Y1/Cr/Y2 byte order |
| YUV422_YUYV | 4:2:2 YCbCr interleaved encoding (half horizontal chroma resolution), Y1/Cb/Y2/Cr byte order |
| YUV444_Planar | 4:4:4 YCbCr planar encoding (full chroma resolution) |
| YUV422_Planar | 4:2:2 YCbCr planar encoding (half horizontal chroma resolution); chroma samples are coaligned with left luma sample |
| YUV420_Planar | 4:2:0 YCbCr planar encoding (half horizontal/vertical chroma resolution); chroma samples are midway between left luma samples |
| YUV411_Planar | 4:1:1 YCbCr planar encoding (quarter horizontal chroma resolution); chroma samples are coaligned with leftmost luma sample |
| YUV410_Planar | 4:1:0 YCbCr planar encoding (quarter horizontal/vertical chroma resolution) |
| YUV420i_Planar | 4:2:0 YCbCr interlaced planar encoding (quarter horizontal/vertical chroma resolution). Chroma samples are coaligned with the left luma sample in each 2x2 block and centered vertically. However, for each plane, the even scanlines correspond to one field while the odd scanlines correspond to another. This means that the vertical relationship between chroma samples is different between even and odd fields. |
| YUV420it_Planar | Same as the even (top) scanlines of the YUV420i_Planar format. In this format, the chroma samples are coaligned with the left luma samples of each 2x2 block, but positioned one-quarter of the way down from the top samples to the bottom ones. |
| YUV420ib_Planar | Same as the odd (bottom) scanlines of the YUV420i_Planar format. In this format, the chroma samples are coaligned with the left luma samples of each 2x2 block, but positioned three-quarters of the way down from the top samples to the bottom ones. |
| *_FR | Same as the base format, but using full range encoding (0-255 for luma and chroma). |
| *_709 | Same as the base format, but using the Rec. 709 color space instead of Rec. 601. |
| VDXA_RGB | Video filters only: 3D accelerated RGB image format. |
| VDXA_YUV | Video filters only: 3D accelerated YCbCr image format (Rec. 601 / limited-range). |
All undecorated YCbCr encodings use the Rec. 601 color space, with
luminance having a range of 16-235 for black to white and chrominance
using 16-240. Formats with the _709 tag use the Rec. 709 color space
instead, which is usually used for high-definition (HD) video. _FR tag
are full-range and use the full 0-255 range for both luma and chroma.
