| dstStep | Destination buffer step size (width of the buffer in bytes). | |
| imgSize | Specifies the dimensions of an entire image. | |
| pDst | Pointer to a location in a destination buffer. | |
| pDst[3] | Pointer to a location in a three-channel planar destination buffer (array values point to a location in each plane). | |
| pSrc[3] | Pointer to a location in a three-channel planar source buffer (array values point to a location in each plane). | |
| roiSize | Specifies the height and width of an ROI. | |
| srcStep[3] | Source three-channel planar buffer step size (array values define width of each plane in bytes). |
These functions convert data in an ROI in a source buffer from the YUV color space with 4:2:0 chroma subsampling to the RGB model, and write the converted data to a destination buffer.
The repeating versions of the functions step through an ROI in a source buffer and write the converted data to a destination buffer.
A YUV image with 4:2:0 chroma subsampling (pSrc) is converted to a gamma-corrected RGB image (pDst).
The following conversion formulas are used:
R = Y + 1.140*V G = Y - 0.394*U - 0.581*V B = Y + 2.032*U
Versions of the functions that don't specify an ROI apply the conversion to the whole image buffer.
