How Can I Crop an Image Using C#?

Crop image using C#

Image cropping refers to removing the unwanted parts of the edges of the image. In C#, you can use the Bitmap class to implement image cropping. Here's a simple way to crop an image:

using System.Drawing;

private static Image CropImage(Image img, Rectangle cropArea)
{
   Bitmap bmpImage = new Bitmap(img);
   return bmpImage.Clone(cropArea, bmpImage.PixelFormat);
}

Usage:

To crop an image, provide the original image and a Rectangle object that defines the cropping area. A Rectangle object specifies the left, top, width, and height of the area to be preserved. The CropImage method will return a new Image object containing the cropped part.

Example:

Consider the following usage:

Image originalImage = Image.FromFile("image.png");

Rectangle cropArea = new Rectangle(100, 100, 200, 300);
Image croppedImage = CropImage(originalImage, cropArea);

In this example, a region of the original image starting at coordinates (100, 100) with a width of 200 pixels and a height of 300 pixels will be cropped, and the result will be stored in the croppedImage variable.
