If you are working on an image editing application and you need an easy-to-implement yet precise cropping mechanism, this article is going to help you a lot. Because in this article, you will learn how to crop an image in C# in a few simple steps.
Image editing is quite common these days and in various cases, we need to manipulate the images to get the desired results. Recently, we have covered how to resize, rotate and flip images programmatically. Today, we are going to show you how to crop images using C# in your .NET applications. We will discuss how to perform image cropping using shift values or with a rectangle.

How to Crop an Image in C#
Aspose.Imaging for .NET provides two ways to crop an image. In the first method, we need to provide left, right, top, and bottom shift values. Whereas, in the second method, we define a rectangle to crop a certain area of an image.
In the following sections, we will demonstrate how to use both of the above-mentioned methods to crop images in C#.
Crop Images with Shift Values in C#
The following are the steps for cropping an image using shift values in C#.
- First, load the image into a RasterImage object using Image.Load() method.
- Cache the image for better performance.
- Define left, right, top and bottom shift values.
- Pass the shift values to RasterImage.Crop() method to crop the image.
- Save the cropped image using RasterImage.Save() method.
The following code sample shows how to crop an image in C#.
The following is the input image that we used for cropping.
Below is the resultant cropped image.
C# Image Cropping using Rectangle
You can also define a rectangle to crop the desired area of an image. The following steps demonstrate image cropping with a rectangle in C#.
- First, load the image into a RasterImage object using Image.Load() method.
- Then, cache the image.
- Create a Rectangle object and initialize it with the desired size.
- Pass the Rectangle object to RasterImage.Crop() method to crop the image.
- Save the cropped image using RasterImage.Save() method.
The following code sample shows how to perform image cropping with a rectangle in C#.
