PolygonY property (Main Control)

Visual Basic example
Visual C++ 4.0 example
Visual J++ example

Syntax float PolygonY (short iIndex);

Overview: Refer to Creating and Using a Bitmap Region.

Remarks

Specifies the Y coordinate of a vertex a polygonal region.

The position is relative to the LEAD bitmap in memory. The unit of measure is determined by the ScaleMode property.

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:

PolygonX property
PolygonY property

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