crop-images-with-rectangle.cs

// Load the image.
using (RasterImage rasterImage = (RasterImage)Image.Load("image.png"))
{
    // Before cropping, the image should be cached for better performance.
    if (!rasterImage.IsCached)
    {
        rasterImage.CacheData();
    }

    // Create an instance of Rectangle class with desired size and crop the image.
    Rectangle rectangle = new Rectangle(20, 20, 20, 20);             
    rasterImage.Crop(rectangle);

    // Save cropped image.
    rasterImage.Save("cropped.png");
}

crop-images.cs

// Load the image to be cropped.
using (RasterImage rasterImage = (RasterImage)Image.Load("image.png"))
{
    // Before cropping, the image should be cached for better performance.
    if (!rasterImage.IsCached)
    {
        rasterImage.CacheData();
    }

    // Define shift values for all four sides.
    int leftShift = 10;
    int rightShift = 10;
    int topShift = 50;
    int bottomShift = 50;

    // Based on the shift values, apply the cropping on image. Crop method will shift the image bounds toward the center of image.
    rasterImage.Crop(leftShift, rightShift, topShift, bottomShift);

    // Save cropped image.
    rasterImage.Save("cropped.png");
