Syntax

C++/CLI

Java

Python

public bool IsPresent { get; }

public boolean isPresent()

public: 
property bool IsPresent { 
   bool get(); 
}

IsPresent # get  (CodecsCodecInformation)

Property Value

true if the codec is present on the system; false, otherwise. The default value is false.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg;
