DeblurLevel

DeblurLevel determines the efforts used to process the blurriness of the barcode. It is defined as below:

Value Type Value Range Default Value Template Structure Type
int [0, 9] 9 ImageParameter/FormatSpecification

Remarks
If you have a blurry image, you can set this property to a larger value. The higher the value set, the more effort the library will spend to decode images, but it may also slow down the recognition process.
DeblurLevel is now deprecated. It still works in the current version but could be removed in the near future. We recommend using DeblurModes instead. Migration mapping:

Setting Methods

DeblurLevel is supported to be set through RuntimeSetting or JSON template.

As PublicRuntimeSettings Member

DeblurLevel can be set dynamically during runtime as a member of PublicRuntimeSettings struct.

Code Snippet in C++

//...other codes
PublicRuntimeSettings* pSettings = new PublicRuntimeSettings;
int errorCode = reader->GetRuntimeSettings(pSettings);
pSettings->deblurLevel = 1;
reader->UpdateRuntimeSettings(pSettings);
delete pSettings;
//...other codes
