Level shift from signed 16s to unsigned 8u
SSE2
| FwStatus | fwiAdd128_JPEG_16s8u_C1R | ( | const Fw16s * pSrc, int srcStep, Fw8u * pDst, int dstStep, FwiSize roiSize ); |
| dstStep | Destination buffer step size (width of the buffer in bytes). | |
| pDst | Pointer to a location in a destination buffer. | |
| pSrc | Pointer to a location in a source buffer. | |
| roiSize | Specifies the height and width of an ROI. | |
| srcStep | Source buffer step size (width of the buffer in bytes). |
This function steps through a block of signed 16-bit data with values in the range [-128, 127] in a source buffer, converts the source data to 8-bit unsigned values in the range [0, 255], and writes the converted data to a destination buffer.
