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 for converting a LEADTOOLS Leadtools.RasterImage to and from a Windows GDI or GDI+ image objects.

The RasterImageConverter class contains the following functionality:

Method	Description
ConvertToImage	Converts a LEADTOOLS Leadtools.RasterImage to GDI+ System.Drawing.Image
ConvertFromImage	Converts a GDI+ System.Drawing.Image to LEADTOOLS Leadtools.RasterImage
ChangeToImage	Converts a LEADTOOLS Leadtools.RasterImage to GDI+ System.Drawing.Image sharing the same memory.
MakeCompatible	Makes a Leadtools.RasterImage pixel and color format compatible with GDI+
TestCompatible, GetNearestBitsPerPixel, IsValidBitsPerPixel and GetNearestPixelFormat	Utility methods for testing and making a LEADTOOLS Leadtools.RasterImage GDI+ compatible
FromHBitmap and ToHBitmap	Converts a Leadtools.RasterImage to and from a GDI DDB (Device Dependant Bitmap)
ChangeFromHBitmap and ChangeToHBitmap	Converts a Leadtools.RasterImage to and from a GDI DDB (Device Dependant Bitmap) while sharing the same memory
ToWmf, FromWmf, ToEmf and FromEmf	Converts a Leadtools.RasterImage to and from a Windows Metafile or Enhanced Metafile
ChangeToWmf, ChangeFromWmf, ChangeToEmf and ChangeFromEmf	Converts a Leadtools.RasterImage to and from a Windows Metafile or Enhanced Metafile while sharing the same memory
