Level shift from unsigned 8u to signed 16s
| FwStatus | fwiSub128_JPEG_8u16s_C1R | ( | const Fw8u * pSrc, int srcStep, Fw16s * 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 unsigned 8-bit data in a source buffer, converts the source data to signed values in the range [-128, 127], and writes the converted data to a destination buffer.
