Aspose::BarCode::Common::ProcessorSettings class

ProcessorSettings class

ProcessorSettings allow to recognize barcodes with multi-threaded increasing of performance.

class ProcessorSettings : public System::Object

Methods

MethodDescription
get_MaxAdditionalAllowedThreads() constSpecify the maximal number of additional threads to run code in parallel.
get_UseAllCores() constIs needed to use all cores.
get_UseOnlyThisCoresCount() constSpecify the number of cores to use. You need to change the property “UseAllCores” to “false”.
set_MaxAdditionalAllowedThreads(int32_t)Specify the maximal number of additional threads to run code in parallel.
set_UseAllCores(bool)Is needed to use all cores.
set_UseOnlyThisCoresCount(int32_t)Specify the number of cores to use. You need to change the property “UseAllCores” to “false”.

Remarks

This sample shows how to use ProcessorSettings to add maximum multi-threaded performnce

[C#]
int workerThreads = Environment.ProcessorCount * 2;
int portThreads = Environment.ProcessorCount * 2;
System.Threading.ThreadPool.GetMinThreads(out workerThreads, out portThreads);
System.Threading.ThreadPool.SetMinThreads(Math.Max(workerThreads, Environment.ProcessorCount* 2), portThreads);
System.Threading.ThreadPool.GetMaxThreads(out workerThreads, out portThreads);
System.Threading.ThreadPool.SetMaxThreads(Math.Max(workerThreads, Environment.ProcessorCount* 4), portThreads);
BarCodeReader.ProcessorSettings.MaxAdditionalAllowedThreads = Environment.ProcessorCount* 2;

//this allows to use all cores for single BarCodeReader call
BarCodeReader.ProcessorSettings.UseAllCores = true;
//this allows to use current count of cores
BarCodeReader.ProcessorSettings.UseAllCores = false;
BarCodeReader.ProcessorSettings.UseOnlyThisCoresCount = Math.Max(1, Environment.ProcessorCount / 2);
[VB.NET]
Dim workerThreads As Integer = Environment.ProcessorCount * 2
Dim portThreads As Integer = Environment.ProcessorCount * 2
System.Threading.ThreadPool.GetMinThreads(workerThreads, portThreads)
System.Threading.ThreadPool.SetMinThreads(Math.Max(workerThreads, Environment.ProcessorCount* 2), portThreads)
System.Threading.ThreadPool.GetMaxThreads(workerThreads, portThreads)
System.Threading.ThreadPool.SetMaxThreads(Math.Max(workerThreads, Environment.ProcessorCount* 4), portThreads)
BarCodeReader.ProcessorSettings.MaxAdditionalAllowedThreads = Environment.ProcessorCount* 2

'this allows to use all cores for single BarCodeReader call
BarCodeReader.ProcessorSettings.UseAllCores = True
'this allows to use current count of cores
BarCodeReader.ProcessorSettings.UseAllCores = False
BarCodeReader.ProcessorSettings.UseOnlyThisCoresCount = Math.Max(1, Environment.ProcessorCount / 2)
