Summary

Allocates three arrays and updates them with the R, G and B profile for each pixel in a specific line.

Syntax
C#
VB
Java
Objective-C
C++
public class LineProfileCommand : RasterCommand 
Public Class LineProfileCommand  
   Inherits RasterCommand 
@interface LTLineProfileCommand : LTRasterCommand 
public class LineProfileCommand extends RasterCommand 
public ref class LineProfileCommand : public RasterCommand   

Remarks
  • This class supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command support signed images.
  • This command does not support 32-bit grayscale images.
