IsSlowInformation Property

Summary

Identifies whether a particular file codec has been marked as taking a relatively long time to load a file.

Syntax

C++/CLI

Java

Python

public bool IsSlowInformation { get; }

public boolean isSlowInformation()

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

IsSlowInformation # get  (CodecsCodecInformation)

Property Value

true if the codec takes a long time to load a file; false, otherwise. The default value is false.

Remarks

Value that indicates whether the codec takes a long time to load. There are three phases used in identifying a file format. The first phase checks the first few bytes. The second phase checks the file extension. The third phase tries all available codec filters. When this value is 'true', it means that the file format can not be identified by looking at the first few bytes of the file.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg; 
 
 
public void GetCodecInformationExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   CodecsCodecInformation codecInfo = codecs.GetCodecInformation("Tif"); 
   Debug.WriteLine("CheckedByInformation : {0}", codecInfo.CheckedByInformation); 
   Debug.WriteLine("ExtensionList : {0}", codecInfo.ExtensionList); 
   Debug.WriteLine("IsIgnored : {0}", codecInfo.IsIgnored.ToString()); 
   Debug.WriteLine("IsPresent : {0}", codecInfo.IsPresent.ToString()); 
   Debug.WriteLine("IsSlowInformation : {0}", codecInfo.IsSlowInformation.ToString()); 
   Debug.WriteLine("LoadMode : {0}", codecInfo.LoadMode.ToString()); 
   Debug.WriteLine("Name : {0}", codecInfo.Name); 
 
   // Parse the load modes 
   CodecsCodecLoadMode[] loadModes = (CodecsCodecLoadMode[])Enum.GetValues(typeof(CodecsCodecLoadMode)); 
   foreach(var loadMode in loadModes) 
   { 
      codecs.SetCodecsInformation(codecs.GetCodecsInformation()); 
      Debug.WriteLine($"Load mode: {loadMode}"); 
   } 
 
   // change the extensions that the ptk filter tries to handle 
   codecInfo.ExtensionList = "ptk;ptoka;ptoca;ptca;ptka"; 
   codecs.SetCodecInformation(codecInfo); 
 
   // re-display the new settings 
   codecInfo = codecs.GetCodecInformation("tif"); 
   Debug.WriteLine("ExtensionList : {0}", codecInfo.ExtensionList); 
 
   // Clean up 
   codecs.Dispose(); 
}
