ObjectInformationCommand Class

Summary
Determines the position, orientation and roundness of the object in the image.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public class ObjectInformationCommand : RasterCommand 
@interface LTObjectInformationCommand : LTRasterCommand 
public class ObjectInformationCommand 
    extends RasterCommand 
public ref class ObjectInformationCommand : public RasterCommand   
class ObjectInformationCommand(RasterCommand): 
Remarks
  • All the objects in the image are considered to be a single object. This command determines various attributes of the object in the image to identify the objects and to determine their position and orientation. If you do not need certain values pass null instead.
  • The results point and angle information obtained by this command are multiplied by 100 in order to obtain more precision. To get the actual results, divide by 100.
  • This command 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 does not support signed data images.
  • This command does not support 32-bit grayscale images.
Example

Run the ObjectInformationCommand on an image.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void ObjectInformationCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg")); 
 
   // Prepare the command 
   //Get the objects center of mass and it's roundness. I am not interested in the axis' orientation, so I pass NULL_ 
   ObjectInformationCommand command = new ObjectInformationCommand(false); 
   command.Run(image); 
 
   MessageBox.Show("Angle = " + command.Angle + "\n" + 
      "Roundness = " + command.Roundness + "\n" + 
      "X = " + command.CenterOfMass.X + "\n" + 
      "Y = " + command.CenterOfMass.Y); 
 
}

{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
