Syntax

C++

[SerializableAttribute()] 
public class AnnLinearGradientBrush : AnnBrush

  
<SerializableAttribute()> 
Public Class AnnLinearGradientBrush  
   Inherits Leadtools.Annotations.AnnBrush 
   Implements System.ICloneable

[SerializableAttribute()] 
public ref class AnnLinearGradientBrush : public Leadtools.Annotations.AnnBrush, System.ICloneable

Remarks

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

Example

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); 
   } 
}

Imports Leadtools 
Imports Leadtools.Annotations 
Imports Leadtools.Codecs 
Imports Leadtools.WinForms 
 
Private Sub AnnLinearGradientBrush_AnnLinearGradientBrush(ByVal graphics As Graphics, ByVal converter As AnnUnitConverter, ByVal rc As AnnRectangle) 
   Dim annBrush As AnnLinearGradientBrush = New AnnLinearGradientBrush(Color.Red, Color.Blue, LinearGradientMode.Horizontal) 
   Dim gdiBrush As Brush = annBrush.Create(converter, rc) 
   Try 
      Dim rect As RectangleF = rc.ConvertTo(converter, AnnUnit.Pixel).ToRectangleF() 
      graphics.FillRectangle(gdiBrush, rect) 
   Finally 
      CType(gdiBrush, IDisposable).Dispose() 
   End Try 
End Sub
