| 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. | |
| pSrcDst | Pointer to a location in a buffer that contains both the source and destination. | |
| roiSize | Specifies the height and width of an ROI. | |
| scaleFactor | Specifies the integer scaling factor for the Sfs operation. The returned result is multiplied by 2^(-scaleFactor). | |
| srcDstStep | Source and destination buffer step size in bytes (width of both buffers in bytes). | |
| srcStep | Source buffer step size (width of the buffer in bytes). |
These functions step through an ROI in a source buffer and calculate the natural logarithms of the source data.
Results can be written back to the source location or to a destination buffer.
The 8-bit unsigned and 16-bit signed versions of the functions perform an integer scaling operation before writing the results.
