POINT_TYPE

enum POINT_TYPE

Meanings that can be assigned to a point in pure geometric terms.

For example, a circle has a center point and four quadrant points.

These can be combined using bitwise OR if a point has multiple meanings.

Enumerator
PT_NONE	No specific point type.
PT_CENTER	The point is the center of something.
PT_END	The point is at the end of a segment, arc, etc.
PT_MID	The point is at the middle of a segment, arc, etc.
PT_QUADRANT	The point is on a quadrant of a circle (N, E, S, W points).
PT_CORNER	The point is a corner of a polygon, rectangle, etc (you may want to infer PT_END from this)
PT_INTERSECTION	The point is an intersection of two (or more) items.
PT_ON_ELEMENT	The point is somewhere on another element, but not some specific point. (you can infer this from some other point types)
