Leadtools Namespace : RasterRegion Class |
The RasterImage object contains a region of interest value that can be used to limit the portion available for updating when using the image processing command. The region can be set using a geometric shape such as RasterImage.AddRectangleToRegion and RasterImage.AddEllipseToRegion or with image data attributes such as RasterImage.AddColorToRegion and RasterImage.AddMaskToRegion.
At any point, you can get a copy of the region inside a RasterImage object using the RasterImage.GetRegion method and update the region inside an image using the RasterImage.SetRegion method.
The RasterRegion class provides a platform independent representation of a region of interest in an image that can be used in any platform supported by LEADTOOLS such as GDI, GDI+, WPF and Silverlight.
To convert a LEADTOOLS RasterRegion object to/from a device dependent region, you can use the following helper classes:
The RasterRegion class implements the System.IDisposable interface, so you must call System.IDisposable.Dispose on any region objects you create after using it.
