public class ObjectInformationCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration

Public Class ObjectInformationCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As ObjectInformationCommand

public sealed class ObjectInformationCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTObjectInformationCommand : LTRasterCommand

public class ObjectInformationCommand extends RasterCommand

function Leadtools.ImageProcessing.Effects.ObjectInformationCommand()

public ref class ObjectInformationCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

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.

Run the ObjectInformationCommand on an image.
