To get the RasterRegion object that describes the current image region, use GetRegion.
To update an existing region, you specify how the new region is to be combined with the existing one using the combineMode parameter. For more information, refer to RasterRegionCombineMode.
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. The RasterRegion class contains extensive methods and properties to manipulate the region data and save/load it to a byte array.
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.
For more information, refer to Creating a Region.
For more information, refer to Saving A Region.
