GDI+

[Simon Morris]

I am writing a mapping program in VB.NET 2003. I have drawn
the coast line using Graphics.DrawLines. I now have about 3,500 small
islands around the coast line. Some of the islands are only 4 or 5 plots
and some of the larger islands are 400 to 500 plots. I was going to use
Graphics.DrawPolygon Method but it takes a while to draw 3,500
islands. That is the best way to draw 3,500 polygons?

Hi Simon,

This might be a good time to start learning about DirectX.

There won't be a faster way using GDI+. Maybe you can increase
performance by not drawing some of the islands and only showing a part
of the map at one time.
