Member name	Value	Description
mcsfmmDefault	0	Default ordering. Currentlythis is the only acceptable value for McRegions (for McRegions, the source mask foreground bits are just used as foreground bits to be labeled for connected region features based on the state of the mcofConnect8 McFeatures.OptionFlags)
mcsfmmPointsLeftTop	1	For McPoints only, a pointfeature is set to left, top bit of each source mask blob.
mcsfmmPointsCentroid	2	For McPoints only, a pointfeature is set to the centroid bit of each source mask blob. The centroid is the mean X,Y coordinate of all foreground bits in the blob. Should the centroid fall between pixel centers, the point coordinates will be fractional values (see mcsfmmIntegralCentroidPoint for a way to ensure points placed on pixel centers).
mcsfmmPointsIntegralCentroid	3	For McPoints only, a pointfeature is set to the centroid bit of each source mask blob, rounded to the closest pixel center. The centroid is the mean X,Y coordinate of all foreground bits in the blob. Should the centroid fall between pixel centers, the point coordinates will be rounded to the nearest pixel center (see mcsfmmCentroidPoint for a way to place points on the fractional centroid). This is the default method for McPoints.Threshold and McPoints.SetFromMask.
mcsfmmLinesLongestStraight	10	For McLines only, a linefeature is created as the straight line connecting the extreme points of each source mask blob. The extreme points are the two points on the boundary that are farthest apart from each other. This is the default method.
mcsfmmLinesExtremeBoundaryAvg	11	For McLines only, a linefeature is created as a polyline traversing the extreme points of each source blob (the boundary points most distal from each other). Each point in this traversal is the average of coordinates perpendicular to the straight line connecting the extreme points (see mcsfmmLinesLongestStraight for a way to get this line). This method works well for blobs that define approximately straight lines but are asymetrical about the line (see mcsfmmMajorAxisAlignedLines for a similar method that works best for symetrical blobs). It will not work for lines that curve back on themselves (e.g. the letter "C", any spiral shape, etcetera). Also, note that for rectangular input blobs, the line will be a diagonal one rather than a horizontal one; use the mcsfmmMajorAxisAlignedLines method to get a horizontal line.
mcsfmmLinesMajorAxisAlignedAvg	12	For McLines only, a linefeature is created as a polyline traversing the longest bounds of a rectangle aligned along the major axis of an equivalent ellipse fit to each source blob. Each point in this traversal is the average of coordinates perpendicular to the long side of the rectangle. This method works well for blobs that define approximately straight lines through symetrical blobs (see the mcsfmmLinesExtremeBoundaryAvg for a method that may work better for asymetrical blobs). It will not work for lines that curve back on themselves (e.g. the letter "C", any spiral shape, etcetera). Also, note that for rhombus shaped blobs, this method's lines will generally not align with the longest axis of the rhombus; use the mcsfmmLinesExtremeBoundaryAvg to get that behavior.
mcsfmmGetOrSetNoDisplayLimit	256	On assignment, doesnot actually change the SetFromMaskMethod property value, but instead primes the next access or assignment to the SourceFlags property, a scalar long value, to get or set the current value of features count beyond which no linked display is done. The default for this value is in a Settings: "Features" module, "Limits" section, "NoDisplayFeaturesCount" keyname, as a "long" value.

Remarks

The method determines how features are created from source bit mask blobs.
