Simplify a Polygon by transforming its vertices?


This attribute controls the behaviour of the AST_SIMPLIFY method when applied to a Polygon. The simplified Polygon is created by transforming the vertices from the Frame in which the Polygon was originally defined into the Frame currently represented by the Polygon. If SimpVertices is non-zero (the default) then this simplified Polygon is returned without further checks. If SimpVertices is zero, a check is made that the edges of the new Polygon do not depart significantly from the edges of the original Polygon (as determined by the uncertainty associated with the Polygon). This could occur, for instance, if the Mapping frrm the original to the current Frame is highly non-linear. If this check fails, the original unsimplified Polygon is returned without change.
Integer (boolean).


All Polygons have this attribute.
