Code: Select all
gdViewer1.AddFreeHandAnnotInteractive(this.useColor, (float)(0.02), System.Drawing.Drawing2D.LineCap.Flat, System.Drawing.Drawing2D.LineCap.Flat, 1,true);
1. My undo button looks like this:
Code: Select all
gdViewer1.DeleteAnnotation(gdViewer1.GetAnnotationCount() - 1);
2. Is there a method to call that would end their mode with the freehand tool, perhaps a selection mode method??
