LineProfileCommand Class








Members 
Allocates three arrays and updates them with the R, G and B profile for each pixel in a specific line.
Object Model
Syntax
'Declaration
 

Public Class LineProfileCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 

Dim instance As LineProfileCommand
public sealed class LineProfileCommand : Leadtools.ImageProcessing.IRasterCommand  
@interface LTLineProfileCommand : LTRasterCommand
public class LineProfileCommand extends RasterCommand
function Leadtools.ImageProcessing.Color.LineProfileCommand()
Remarks
For more information, refer to Introduction to Image Processing With LEADTOOLS.
In Silverlight 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.
Example

Run the LineProfileCommand on an image.
