RasterEdge C#.NET image resizer library control SDK is a 100% clean .NET solution, which is designed to help C# developers resize target image file to desired settings. Using this Visual C# .NET image resizing control, developers can adjust, enlarge or shrink the size of source image file either vertically or horizontally by a few lines of simple C# code.
Apart from this C# image resizing control, RasterEdge DocImage SDK for .NET (a professional third-party imaging SDK from RasterEdge) also contains other image processing and manipulating controls, like C#.NET image cropping control
, C#.NET image rotating control
and image flipping library control
This online tutorial contains both theoretical guidance and sample C# code for developers to resize source image in .NET applications. And this is the article layout of this RasterEdge C#.NET image resize control guide page.

- Embed following dlls of RasterEdge image resizing SDK to your C#.NET class application as references;
Activate the evaluation license key of RasterEdge DocImage SDK for .NET by running the application file "RasterEdge.Imaging License Manager.exe" and copy created "RasterEdgeLicense.txt" to the C# project bin folder where above integrated RasterEdge image resizing dlls are located;Define the Namespace of RasterEdge C#.NET image resizing SDK;Copy the sample C# code (which you can find in following section) and you are able to resize the target image to meet your requirement.
Image Resizing Method in Visual C#
RasterEdge C#.NET image resizer library control offers an easy to use API for developers to resize target image file. The following is the method that this image resizing control has used to enlarge or reduce the target image size.
public static int ApplyResize(REImage img, int width, int height);
Sample C# Code to Resize Image
Using the sample C# code below, you can easily tailor the size of source image file to your desired requirement and save resized image as a new image object in .NET Windows Forms application.
From the given C# code demo, you will find it extremely easy to resize your source image file using RasterEdge C#.NET image resizing control. To put it in another way, if you want to adjust the target image size at your desired values, you just need to enter the required sizing value data by the C# code, that is, ImageProcessing.ApplyResize (reImage, image width value, image height value).
public partial class Form1 : Form
private void button1_Click(object sender, EventArgs e)
string fileName = "c:/Sample.png";
REImage reImage = REFile.OpenImageFile(fileName);
ImageProcessing.ApplyResize(reImage, 500, 500);
REFile.SaveImageFile(reImage, "c:/reimage.png", new PNGEncoder());
