Summary

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

Syntax

Objective-C

C++/CLI

Java

Python

public class LineProfileCommand : RasterCommand

@interface LTLineProfileCommand : LTRasterCommand

public class LineProfileCommand 
    extends RasterCommand

public ref class LineProfileCommand : public RasterCommand

class LineProfileCommand(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.

Example

Run the LineProfileCommand on an image.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color; 
 
 
public void LineProfileCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg")); 
 
   // Prepare the command 
   LineProfileCommand command = new LineProfileCommand(); 
   int[] redData; 
   int[] greenData; 
   int[] blueData; 
   command.FirstPoint = new LeadPoint(0, 0); 
   command.SecondPoint = new LeadPoint(50, 50); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
   redData = command.RedBuffer; 
   greenData = command.GreenBuffer; 
   blueData = command.BlueBuffer; 
 
}
