How to Draw .NET Graphics in C# Program
Before applying the function of image .NET graphics drawing, you need to create a proper Visual C# Windows project first. And this part tells users how to create such a C# application. For VB.NET developers, please go to draw .NET graphics within .NET Imaging SDK in VB.NET. Want to view image and document in WinForms or web applications, please go to draw .NET graphics in WinForms and web document image .NET graphics drawing.
  1. Open and run Microsoft Visual Studio 2005/2008/2010 at first;
  2. Then, you are supposed to create a C#.NET project;
  3. Later, please copy your.NET imaging license text file to the new C# Windows project folder;
  4. Add following image drawing and basic references to your C# project;
    • RasterEdge.Imaging.Drawing.dll
    • RasterEdge.Imaging.Basic.dll
  5. Add following using requirements in C# project:
using System.IO;
using System.Drawing.Printing;
using RasterEdge.Imaging;
using RasterEdge.Imaging.Processing;
using RasterEdge.Imaging.Drawing.Image.Text;
C# .NET Graphics Drawing Methods
Following .NET graphics drawing methods allow programmers and end users to draw rectangle, line, and ellipse images in your C# applications.
public void RectangleDrawing(Pen mypen, Rectangle myRectangle);
public void RectangleDrawing(Pen mypen, Point pt1, Point pt2);
public void EllipseDrawing(Pen maypen, Point pt1, Point pt2, Point pt3, Point pt4);
Entire C# Code to Draw Rectangle, Line & Ellipse on .NET Graphics
From following three parts, users can have a better guidance on how to add rectangle, ellipse and line images on .NET graphics by using given C# sample codes.

C# Code to Draw Rectangle Image on .NET Graphics

Following C# demo code demonstrates how to draw a rectangle image on C#.NET Windows graphics. .NET graphics pre-editing applications includes adjusting .NET graphics background color, four edge data and choosing the image shape that will be drawn.
RasterEdgeImaging Rectangle = new RasterEdgeImaging();

{
Bitmap LoadImage = new Bitmap("C:\\1.jpg");
Graphic Rectangle = Graphics.FromImage(LoadImage);
Pen myPen = new Pen(System.Drawing.Color.Red, 5);
Rectangle myRectangle = new Rectangle(20, 20, 250, 200);
}
Rectangle.RectangleDrawing = (mypen, myrectangle);
Rectangle.Save();

C# Code to Draw Line Image to .NET Graphics

Like drawing rectangle image on .NET graphics, adding a line object to graphics is also easy to be achieved. Please follow the complete C# sample code below to finish this work easily.
RasterEdgeImaging Rectangle = new RasterEdgeImaging();

{
Bitmap LoadImage = new Bitmap("C:\\Sample.png");
Graphic Linear = Graphics.FromImage(LoadImage);
Pen myPen = new Pen(System.Drawing.Color.Red, 5);
Point pt1 = new Point (10.0F, 30.0F);
Point pt2 = new Point (50.0F, 30.0F);
}
Linear.LinearDrawing = (mypen, pt1, pt2);
Linear.Save();

C# Code to Draw Ellipse Image to .NET Graphics

Following Visual C# demo code demonstrates how to draw an ellipse object to .NET graphics. If you are interested image drawing functions in VB.NET project, please have a look at: how to draw and write image text and .NET graphics in VB.NET class.
RasterEdgeImaging Rectangle = new RasterEdgeImaging();

{
Bitmap LoadImage = new Bitmap("C:\\Sample.png");
Graphic Rectangle = Graphics.FromImage(LoadImage);
Pen myPen = new Pen (Color.Black, 3);
Rectangle myRectangle = new Rectangle(20, 20, 250, 200);
}
Ellipse. EllipseDrawing = (mypen, pt1, pt2, pt3, pt4);
Ellipse.Save();
