This brief article covers how to draw lines in C#. It contains the IDE settings, step-by-step program flow, and a runnable code sample for easy line drawing in C#. Moreover, it discusses modifying different properties such as position, length, and color to meet your requirements.
Steps to Draw Lines in C#
- Prepare the system to use Aspose.Drawing to draw lines
- Initiate an instance of the Bitmap class and set the pixel format and image dimensions
- Call the DrawLine method along with the parameters of the color and coordinates
- Export the generated image
The list above enumerates the steps to draw line in C#. The process begins by creating a bitmap of any required width and height and then setting the (x, y) position using coordinates. Furthermore, you may modify the number of lines and the length to meet your requirements.
Code for Easy Line Drawing in C#
| // Initialize a Bitmap class object | |
| Aspose.Drawing.Bitmap bitmap = new Aspose.Drawing.Bitmap(1000, 800, Aspose.Drawing.Imaging.PixelFormat.Format32bppPArgb); | |
| Aspose.Drawing.Graphics graphics = Aspose.Drawing.Graphics.FromImage(bitmap); | |
| // Draw the lines | |
| graphics.DrawLine(new Aspose.Drawing.Pen(Aspose.Drawing.Color.Blue, 2), 10, 10, 900, 10); graphics.DrawLine(new Aspose.Drawing.Pen(Aspose.Drawing.Color.Red, 2), new Aspose.Drawing.PointF(10, 50), new Aspose.Drawing.PointF(900, 50)); | |
| graphics.DrawLine(new Aspose.Drawing.Pen(Aspose.Drawing.Color.Green, 2), 10, 100, 900, 100); graphics.DrawLine(new Aspose.Drawing.Pen(Aspose.Drawing.Color.Yellow, 2), new Aspose.Drawing.Point(10, 150), new Aspose.Drawing.Point(900, 150)); | |
| // Save output drawing image bitmap.Save("DrawLines.jpg"); |
The code snippet demonstrates how to draw a horizontal line in C#. It is a basic version that draws four lines in different colors, however, you can customize it to modify the drawing process. Furthermore, you can manipulate line styles such as continuous and dashed, as well as the color and width of the lines.
This topic discusses the process to draw a straight line in C#. If you need to add text to photos, read the article on Write Text on JPG in C#.
