AVL.ReadMultiplePDF417Codes

Detects and recognizes several PDF417 codes.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax

C++
C#
 
public static void ReadMultiplePDF417Codes
(
	AvlNet.Image inImage,
	AvlNet.Rectangle2D? inRoi,
	AvlNet.CoordinateSystem2D? inRoiAlignment,
	AvlNet.PDF417CodeParams inCodeParams,
	AvlNet.PDF417DetectionParams inDetectionParams,
	bool inAllowMultipleScales,
	IList<AvlNet.PDF417Code> outPDF417Codes,
	out AvlNet.Rectangle2D outAlignedRoi
)

Parameters

Name Type Range Default Description
inImageAvlNet.ImageInput image.
inRoiAvlNet.Rectangle2D?Region of interest. Default value: atl::NIL.
inRoiAlignmentAvlNet.CoordinateSystem2D?Coordinate system for the region of interest. Default value: atl::NIL.
inCodeParamsAvlNet.PDF417CodeParamsSpecification of codes that can be detected.
inDetectionParamsAvlNet.PDF417DetectionParamsSpecification of the way the codes are being detected.
inAllowMultipleScalesboolFalseSpecifies whether codes of different module sizes are expected. Default value: False.
outPDF417CodesSystem.Collections.Generic.IList<AvlNet.PDF417Code>Found PDF417 codes.
outAlignedRoiAvlNet.Rectangle2DInput ROI after transformation (in the image coordinates).

Remarks

In inCodeParams the parameter MinModuleSize should be more or equal to 3. For values less than 3 it is not guaranteed, that ReadMultiplePDF417Codes will process codes properly.
