Parameters

dstStep   Destination buffer step size (width of the buffer in bytes).
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   Pointer to a location in a source buffer.
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   Source buffer step size (width of the buffer in bytes).

Description

These functions step through an ROI in a source buffer, convert the source data from the YUV color space to the RGB color model, and write the converted data to a destination buffer.

A YUV image (pSrc) declared in the ROI (roiSize) 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
