MaximumThreadCount Property

Summary

Gets or sets the maximum number of threads used during processing.

Syntax

C++/CLI

Python

public static int MaximumThreadCount { get; set; }

public: 
static property int MaximumThreadCount { 
   int get(); 
   void set (    int ); 
}

MaximumThreadCount # get and set (RasterDefaults)

Property Value

An Int32 value that represents the maximum number of threads used during processing. Must be a value greater than or equals to 0. Default value is the number of CPUs/Cores in the current machine (System.Environment.ProcessorCount).

Remarks

Currently only the LEADTOOLS JPEG2000 Encoder and Decoder are using this property. More LEADTOOLS encoders/decoders may use this property in the future.

Using two threads with a dual core machine or two CPUs will increase the processing speed significantly if the processing supports parallel processing.

Possible values are:

Value	Description
0	The toolkit will pick the proper number of running threads based on the number of CPUs/Cores of the current machines. Note: the toolkit will calculate this value internally and set it. Getting the value of this property will never return 0.
1	Use one thread only. In this case, the toolkit will not create extra threads for the processing, instead, all operations will be performed in the main thread.
2	Use two threads. The toolkit will create a maximum of two threads for processing if needed.
N	Use N threads. The toolkit will create a maximum of N threads for processing if needed.

Values less than zero will be rejected. Large values, more than the number of CPU/Cores, will not increase performance and might cause resource usage overload which could lead to processing failure.

The MaximumThreadCount property is a global resource used by all LEADTOOLS and is not thread-safe. Make sure to use property thread synchronization if required.
