len   Specifies the number of elements in a buffer.
level   Specifies a threshold level.
pDst   Pointer to a destination buffer.
pSrc   Pointer to a source buffer.
pSrcDst   Pointer to a buffer that is both the source and destination.
value   Specified value.


These functions step through vector elements in a source buffer and compare source data to a specified threshold value.

When the source data is less than the threshold value, the function writes a specified value.

When the source data is greater than or equal to the threshold value, the function writes the value of the source data.

Output data can be written to a destination buffer or back to the source buffer for in-place operation.

The following evaluation formulas are used.

        |value,  pSrc[n] < level|
For fwThreshold_LTVal  pDst[n] = |pSrc[n], pSrc[n] >= level |   |
        |   |

        | value,  abs(pSrc[n]) < level|
For complex variant  pDst[n] = |pSrc[n], pSrc[n] >= level |         |
        |         |
