dstStep   Destination buffer step size (width of the buffer in bytes).
fwCmpOp   Specifies a comparison operation to be performed (fwCmpLess, fwCmpGreater, fwCmpLessEq, fwCmpEq, or fwCmpGreaterEq).
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.
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).
threshold   Threshold for each pixel.
threshold[3]   Three-channel threshold for each pixel.


These functions step through an ROI in a source buffer and compare the source data to a specified threshold value using a specified compare operation.

The compare operation can be "less than", "less than or equal", "equal", "greater than or equal" or "greater than".

When the comparison evaluates as true, the output data is set to the threshold value.

When the comparison evaluates as false, the output data is set to the same value as the source data.

Output data is written back to the same buffer for in-place operation or to a destination buffer.
