Class ReadingSpeed
Specify the reading speed of IronBarcode. Setting a more detailed option will use more CPU and take longer.
Please understand that pre-processing is CPU-heavy and we recommend experimenting with different settings starting with the lowest settings first and gradually working up from there.
Inheritance
Namespace: IronBarCode
Assembly: IronBarCode.dll
Syntax
public sealed class ReadingSpeed : EnumReadingSpeed sets how much image pre-processing IronBarcode applies before reading, trading raw speed against accuracy on awkward inputs, assigned to BarcodeReaderOptions.Speed. Faster, the default, does no pre-processing and reads clean images quickly. Balanced adds light processing to clarify the barcode area, Detailed applies medium processing, and ExtremeDetail applies heavy processing for faint, skewed, or low-quality scans. The reading speed options how-to compares the levels.
var options = new BarcodeReaderOptions { Speed = ReadingSpeed.Balanced };Fields
Balanced
Light Processing is performed to attempt to clarify the barcode area and make it stand out more for the reader.
Declaration
public const ReadingSpeed BalancedField Value
| Type | Description |
|---|---|
| ReadingSpeed |
Detailed
Medium Processing is performed to attempt to clarify the barcode area and make it stand out more for the reader.
This is a CPU-intensive operation. We recommend experimenting with all levels of processing to ensure you are using the weakest one required to improve performance.

ExtremeDetail
Heavy Processing is performed to attempt to clarify the barcode area and make it stand out more for the reader.
Please use this ReadingSpeed if you are trying to read multiple barcodes with the same values in one input file.
This is a very CPU-intensive operation and may still not improve blurry barcodes or noisy images.
