MimZoneOfInfluence

Specifies the identifier of the source of the operation. This parameter must be given an image buffer identifier.

This image buffer must not have a region of interest (ROI) associated with it. Using an image buffer with an ROI will cause an error.

Specifies the identifier of the destination of the resulting image. This parameter must be given an image buffer identifier.

This image buffer must not have a region of interest (ROI) associated with it. Using an image buffer with an ROI will cause an error.

The destination buffer should be deep enough to hold the maximum number of zones (blobs). The maximum label value is 2 ⁿ - 5, where n is the depth of the destination buffer in bits. For example, an 8-bit buffer can be used for a maximum of 251 blobs and a 16-bit buffer can be used for a maximum of 65531 blobs. Note that if the destination buffer depth is too small, several zones might be given the same value.

Specifies the type of 3x3 distance matrix used for the operation. The following table shows each value's respective 3x3 distance matrix for calculating the distance to a neighboring pixel, which is then used for the zone of influence computation.

This parameter must be set to one of the values below.

For controlling the type of 3x3 distance matrix
Value	Description
M_DEFAULT	Same as M_CHESSBOARD.
M_CHAMFER_3_4	Uses a distance algorithm that makes a better approximation to actual Euclidean distance, and is therefore more accurate than M_CHESSBOARD. This is the 3x3 distance matrix: (summarize) Uses a distance algorithm that makes a better approximation to actual Euclidean distance, and is therefore more accurate than M_CHESSBOARD. (more details...)
M_CHESSBOARD	Specifies a chessboard matrix. This operation is faster than M_CHAMFER_3_4. This is the 3x3 distance matrix: (summarize) Specifies a chessboard matrix. (more details...)
