ApplyLinearModalityLookupTableCommand Class

Example 





Members 
Remaps the image pixels by applying a linear transformation described by a rescale slope and an intercept. This class is available in the Document/Medical toolkits only. .NET support WinRT support Silverlight support
Object Model
ApplyLinearModalityLookupTableCommand Class
Syntax
public class ApplyLinearModalityLookupTableCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand  
'Declaration
 
Public Class ApplyLinearModalityLookupTableCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As ApplyLinearModalityLookupTableCommand
public sealed class ApplyLinearModalityLookupTableCommand : Leadtools.ImageProcessing.IRasterCommand  
function Leadtools.ImageProcessing.Core.ApplyLinearModalityLookupTableCommand()
public ref class ApplyLinearModalityLookupTableCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand  
Remarks
For more information, refer to Changing Brightness and Contrast.

In Silverlight and Windows Phone versions of LEADTOOLS, this image processing command will fail if the image data for the RasterImage object is stored internally using a Silverlight WriteableBitmap object. For more information, refer to Image Processing Command Limitations in Silverlight.
