C# GDI+

[codebala]

All, I would like to know how to increase the speed of the GDI object for drawing purpose. I need to draw lines connecting 100000 points. I am using graphics.drawline. But it takes approx 5 seconds to finish the task. How can I reduce the drawing time. CodeBala

You should see some improvement if you call DrawLines instead of DrawLine. Josh

You could try setting the Graphics.SmoothingMode property to HighSpeed before you draw the lines, like this...

e.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighSpeed;

Hope that helps :)

Will, thanks for your reply. But for some reason the HighSpeed was increasing the time to draw. CodeBala

Josh, thanks for your reply. But as per my logic I need to test for the validity of the point before drawing. So I have to use drawline only. Is their any other way??
