Remarks
The LEADTOOLS RasterImage class provides platform independent representation of an image. It serves as a working area for image manipulation and conversion. LEADTOOLS functions use this class for accessing the image in memory and for maintaining the characteristics of the image. This class contains the functionality needed to convert a LEADTOOLS Leadtools.RasterImage to and from a Windows Presentation Foundation (WPF) or Silverlight image objects.



The RasterImageConverter class contains the following functionality:
