DetectGlareCommand Class

Summary

Detects the glare zone in an image.

Syntax

Objective-C

C++

Java

public class DetectGlareCommand : RasterCommand, IInformationCommand

Public Class DetectGlareCommand  
   Inherits RasterCommand

@interface LTKernelDetectGlareCommand : LTRasterCommand

public class DetectGlareCommand extends RasterCommand

public ref class DetectGlareCommand : public RasterCommand

Remarks

Detects the glare zone in an image.
Can be used as a pre-processing step to check image before recognition.
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 supports unsigned data images, but not signed ones.
This command does not support 32-bit grayscale images.
This function can only process entire images. It does not support regions.

Note: All RasterCommands in this assembly modify the underlying properties of the input RasterImage, including but not limited to:

BitsPerPixel
Data
IsMirrored

If you wish to avoid RasterImage property fidelity loss, pass a clone of your RasterImage to all RasterCommands in this assembly.
