CPJ.ClipPLY Method

CPJClipPLY Method

Create a clip polygon from a projected area.

Namespace: GeoEngine.Core.GXNetX
Assembly: geoengine.core.gxnetx (in geoengine.core.gxnetx.dll)

Notes

A rectangular area from (MinX, MinY) to (MaxX, MaxY) is projected throught the PJ. The resulting (non-rectangular) area is then digitized along its edges, then thinned to remove near-collinear points. The thinning is done to any point whose neighbors subtend an angle greater than (180 degrees - maximum deviation). (i.e. if max. dev = 0, only co-linear points would be removed).
