Summary

Enables or disables multithreaded load.

Syntax

C++/CLI

Python

public bool Multithreaded { get; set; }

public:  
   property bool Multithreaded 
   { 
      bool get() 
      void set(bool value) 
   }

Multithreaded # get and set (CodecsHeicLoadOptions)

Property Value

Value	Description
true	To enable multithreaded load
false	To disable multithreaded load

The default value is true.

Remarks

Set this property to true to use multiple threads for loading HEIC files.
