Parameters

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.
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.
threshold[4]   Four-channel threshold for each pixel.
value   Specified value.
value[3]   An array of three specified values.
value[4]   An array of four specified values.

Description

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

When the source data is less than the threshold value, the output data is set to a specified value.

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