Crops the specified rectangle.

public virtual void Crop(Rectangle rectangle)

Parameter	Type	Description
rectangle	Rectangle	The rectangle.

Examples

The following example crops a raster image. The cropping area is be specified via Aspose.Imaging.Rectangle.

[C#]

string dir = @"c:\temp\";

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

    // Crop the image. The cropping area is the rectangular central area of the image.
    Aspose.Imaging.Rectangle area = new Aspose.Imaging.Rectangle(rasterImage.Width / 4, rasterImage.Height / 4, rasterImage.Width / 2, rasterImage.Height / 2);
    rasterImage.Crop(area);

    // Save the cropped image to PNG
    rasterImage.Save(dir + "sample.Crop.png");
