Syntax

short PolygonSize

Overview

Refer to Creating and Using a Bitmap Region.

Remarks

Specifies the size of the array used to store the vertices when creating a polygonal region.

To create a polygonal region, you must first build an ordered array of points for the vertices of the polygon; then create the region based on the array. The PolygonSize property specifies the size of the array. You can either specify a large array to start with, or you can increase the size of the array when necessary (without losing the existing points). For each vertex, you update the array by setting the following indexed properties:

image\sqrblit.gif PolygonX property

image\sqrblit.gif PolygonY property

You can then call the SetRgnPolygon method to add the region to the bitmap.
