Public Enumeration mcGetFeaturePointsExFlags
Members| Member name | Value | Description | |
|---|---|---|---|
| gfpxNone | 0 | no flags | |
| gfpxDefault | 2 | default behavior is gfpxConstantArea | |
| gfpxClosedBoundary | 1 | This flag is forced on forMcRegions and is otherwise off. | |
| gfpxConstantArea | 2 | if set for the mcotFilter or ormcotConvex mcOutlineType operation for a McRegions, conserve the original area within the closed outline. When clear, the outline that is returned is likely to have a different area than the original outline (usually smaller). This flag affects any filtering pass for the mcotConvex operation (non-zero OperationValue), but does not modify the convex hull itself (the area of the convex hull will be the same or larger than the original area). This flag implies that the gfpxClosedBoundary flag is set. | |
| gfpxAdjacentPixels | 4 | If set the feature coordinates aremapped to the closest pixel and then interpolated into one-pixel steps before doing any mcotFilter or mcotConvex mcOutlineType operation. This is equivalent to the mcotNoGaps mcOutlineType operation. For McLines, if the mcofConnect8 bit of the McFeatures.OptionFlags property is clear, then the points are marked such that each pixel along the line is 4-connected to one of its neighbors. By default the mcofConnect8 is set for McLines (though it is clear by default for McRegions), so points will be adjacent but may be only 8-connected. This flag is ignored for the mcotSetNumbers and mcotSetSpacing operations. This flag is illegal for McPoints objects. |
