Annotation brushes are used to fill the interiors of annotation objects like rectangles, ellipses, polygons, etc.

This example uses an AnnLinearGradientBrush to draw a rectangle.
using Leadtools;
using Leadtools.Annotations;
using Leadtools.Codecs;
using Leadtools.WinForms;
private void AnnLinearGradientBrush_AnnLinearGradientBrush(Graphics graphics, AnnUnitConverter converter, AnnRectangle rc)
{
AnnLinearGradientBrush annBrush = new AnnLinearGradientBrush(Color.Red, Color.Blue, LinearGradientMode.Horizontal);
using (Brush gdiBrush = annBrush.Create(converter, rc))
{
RectangleF rect = rc.ConvertTo(converter, AnnUnit.Pixel).ToRectangleF();
graphics.FillRectangle(gdiBrush, rect);
}
}
