How to Crop an Image in C#

Aspose.Imaging for .NET provides two effective methods for cropping images: crop image with shift values and crop image using a defined rectangle.

Crop Images with Shift Values in C#

To crop an image using shift values in C#, follow these steps:

  1. Load the image into a RasterImage object using the Image.Load() method.
  2. Cache the image for improved performance.
  3. Define the left, right, top, and bottom shift values.
  4. Pass the shift values to the RasterImage.Crop() method to crop the image.
  5. Save the cropped image using the RasterImage.Save() method.

Here’s a code sample demonstrating how to crop an image in C#:

C# Image Cropping Using a Rectangle

Another effective method to crop an image is by specifying a rectangle. Here’s how to do it in C#:

  1. Load the image into a RasterImage object using the Image.Load() method.
  2. Cache the image.
  3. Create a Rectangle object and initialize it with the desired dimensions.
  4. Pass the Rectangle object to the RasterImage.Crop() method to crop the image.
  5. Save the cropped image using the RasterImage.Save() method.

Here’s a code sample illustrating how to perform image cropping using a rectangle in C#:
