WebSpecifies the polygon simplification algorithm. POINT_REMOVE —Critical points that preserve the essential shape of a polygon outline are retained, and all other points are removed (Douglas-Peucker). This is the default. BEND_SIMPLIFY —Critical bends are retained, and extraneous bends are removed from a line (Wang-Müller).

If the input geometry is a polygon and a negative distance is specified, then the buffer polygon could be inside the input geometry. The specified distance is in the units of the associated spatial reference.

WebBoundary Fill Algorithm. Introduction: Boundary Fill Algorithm starts at a pixel inside the polygon to be filled and paints the interior proceeding outwards towards the boundary. This algorithm works only if the color with which the region has to be filled and the color of the boundary of the region are different. If the boundary is of one single color, this approach … Web4. Clip the polygon to the window 5. Transform all vertices of all projected and clipped polygons to PDC. Note: Up to this point the same steps must be performed for the regualr z buffer algorithm 6.
