FIL.ReadMultipleBarcodes

Detects and recognizes multiple barcodes on the input image.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void ReadMultipleBarcodes
(
	FilNet.Image inImage,
	FilNet.BarcodeParams inBarcodeParams,
	FilNet.BarcodeDetectionParams inDetectionParams,
	int inMaxBarcodeCount,
	IList<FilNet.Barcode> outBarcodes
)

Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image.
inBarcodeParamsFilNet.BarcodeParamsSpecification of barcodes that can be detected.
inDetectionParamsFilNet.BarcodeDetectionParamsParameters of the barcode detection algorithm.
inMaxBarcodeCountint<1, INF>2Maximum number of barcodes in one image. Default value: 2.
outBarcodesSystem.Collections.Generic.IList<FilNet.Barcode>List of barcodes that have been correctly detected and decoded.

Description

This filter detects barcodes present in the input image and reads their content.

Examples

Two barcodes in a good quality image.

Two barcodes in a blurry image.

Remarks

Minimal bar width requirement

To provide precise detection of the barcode width of the thinnest bar should be at least 1.5 pixels.

Depending on the barcode format guard or start/end code patterns must be readable.

Pharmacode usage

The pharmacode barcode type can be read correctly in both directions. To get results from both directions use a Pharmacode and PharmacodeInversed barcode types.

Before decoding a Pharmacode the code orientation angle is normalized to a range from -45° to 135° what makes the code decoding more stable

Results of reading using a different Pharmacode directions: Pharmacode = 23 and PharmacodeInversed = 16.
