Create Ellipse Annotation Program in C#
This part will show users how to create the ellipse annotation application in Visual C# class. Please follow the detailed tips below to achieve a proper C# project. Want to get help on ellipse annotation in VB.NET, please go to how to add ellipse annotation to single or multi-page images in VB.NET class.
  1. Open Microsoft Visual Studio (2005 or any later version);
  2. Create a Windows project in Visual C# class;
  3. Copy the license file to "Debug" folder under the "bin" file of your created C# Windows project;
  4. Integrate following image annotation DLLs to your Visual C# applications;
    • RasterEdge .Imaging.Basic.dll
    • RasterEdge .Imaging.Annotation.dll
  5. Use following using statements in C# image application:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using RasterEdge.Imaging.Annotation;
using System.Diagnostics;
using RasterEdge.Imaging.Annotation.Basic;
C# Method to Create Image Ellipse Annotation
With following completely developed APIs in C# code, users can easily create customized ellipse annotation on image. Specific customizable annotation properties include: annotation edge data, location, font style and annotation brush shadow.
public static EllipseAnnotation CreateEllipseAnnotation(float x, float y, float w, float h);
public static EllipseAnnotation CreateEllipseAnnotation(float x, float y, float w, float h, AnnotationPen outline, AnnotationBrush fill,
AnnotationBrush shadow, float shadowX, float shadowY);
Create Image Ellipse Annotation Example in C#
As displayed in following C# sample code, when programming image ellipse annotation, users can change the parameter of annotation width & height and filled shape properties. Nay more, users are supposed to save the annotated image to variable image formats.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using RasterEdge.Imaging.Annotation;
using System.Diagnostics;
using RasterEdge.Imaging.Annotation.Basic;

namespace RasterEdge.Imaging.Demo.Annotation
public class EllipseAnnotationDemo
* SDK Dependency:
* RasterEdge.Imaging.Annotation.dll

public static void Test()

EllipseAnnotation obj = new EllipseAnnotation();
// set annotation size
obj.X = 60.0F;
obj.Y = 45.0F;
obj.Width = 156.0F;
obj.Height = 228.0F;

//set annotation edge property
obj.OutLine = new LinePen();
obj.OutLine.Width = 5.0F;//set annotation edge width
obj.OutLine.Brush = new AnnotationBrush();
obj.OutLine.Brush.FillType = RasterEdge.Imaging.Annotation.FillType.Solid;//set annotation edge style
obj.OutLine.Brush.Solid_Color = Color.Blue;//set annotation edge color

//set filled shape property
obj.Fill = new AnnotationBrush();
obj.Fill.FillType = RasterEdge.Imaging.Annotation.FillType.Solid;//set filled shape style
obj.Fill.Solid_Color = Color.Gray;//set filled shape color

//set shadow property
obj.ShadowFill = new AnnotationBrush();
obj.ShadowFill.FillType = RasterEdge.Imaging.Annotation.FillType.Solid;//set shadow style
obj.ShadowFill.Solid_Color = Color.DarkGreen;//set shadow color
obj.ShadowX = 20.0F;//set shadow position
obj.ShadowY = 20.0F;
obj.ShowShadow = true;//show shadow or not

string folderName = "C:/";
Bitmap img = obj.CreateAnnotation();
img.Save(folderName + "EllipseAnnotation.png");
catch (Exception ex)
