Parameters

len   Specifies the number of elements in a buffer.
levelGT   Specifies a threshold level for greater-than comparison.
levelLT   Specifies a threshold level for less-than comparison.
pDst   Pointer to a destination buffer.
pSrc   Pointer to a source buffer.
pSrcDst   Pointer to a buffer that is both the source and destination.
valueGT   Specifies a value to set when a greater-than comparison evaluates as true.
valueLT   Specifies a value to set when a less-than comparison evaluates as true.

Description

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

The levelLT parameter must be less than the levelGT parameter.

When the source data is less than levelLT, the function writes the value specified by valueLT.

When the source data is greater than the value specified by levelGT, the function writes the value specified by valueGT.

When the source data is within the range defined by levelLT and levelGT, 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.

           |valueLT, pSrc[n] < levelLT|
For fwThreshold_LTValGTVal:  pDst[n] = |pSrc[n], levelLT <= pSrc[n] <= levelGT  |      |
           |valueGT, pSrc[n] > levelGT|
