SYMPTOMS
On a Microsoft Windows XP-based computer, you cannot draw an exact polygon that has gradient fill effects when you use the FillPolygon method and the PathGradientBrush class in the Microsoft .NET Framework 1.1. Additionally, rounding errors may distort the adjoining edges of the polygon.

This problem also occurs when you use the GDI+ API to draw a polygon in Windows XP.

Note This problem does not occur when you draw a polygon in a single color.



CAUSE
This problem occurs because the calculation method for polygons that have gradient fill effects differs from the calculation method for polygons that have solid fill effects.
