KernelType Property

Summary

Gets the type of the LEADTOOLS kernel.

Syntax

Objective-C

C++/CLI

Java

Python

public static RasterKernelType KernelType { get; }

+ (LTRasterKernelType)kernelType

public static RasterKernelType getKernelType();

public: 
static property RasterKernelType KernelType { 
   RasterKernelType get(); 
}

KernelType # get  (RasterSupport)

Property Value

Aa RasterKernelType enumeration member indicating the LEADTOOLS kernel type.

Remarks

The following table describes the types of LEADTOOLS kernels:

Kernel	Description
Release	This is the Release kernel.
Evaluation	This is the Evaluation kernel, which has all features unlocked, but displays an "eval" message during execution. This kernel will also expire.

Example

This example will check the LEADTOOLS kernel type and whether it has expired

Java

using Leadtools; 
 
 
public void LeadtoolsKernelExample() 
{ 
	// show current kernel 
	switch (RasterSupport.KernelType) 
	{ 
		case RasterKernelType.Release: 
			Console.WriteLine("Release kernel"); 
			break; 
 
		case RasterKernelType.Evaluation: 
			Console.WriteLine("Evaluation kernel"); 
			// show if the kernel has expired 
			if (RasterSupport.KernelExpired) 
				Console.WriteLine("Evaluation kernel has expired"); 
			else 
				Console.WriteLine("Evaluation kernel has not expired yet"); 
			break; 
	}
