AVL.ReadSinglePDF417Code

Detects and recognizes one PDF417 code.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax

C++
C#
 
public static void ReadSinglePDF417Code
(
	AvlNet.Image inImage,
	AvlNet.Rectangle2D? inRoi,
	AvlNet.CoordinateSystem2D? inRoiAlignment,
	AvlNet.PDF417CodeParams inCodeParams,
	AvlNet.PDF417DetectionParams inDetectionParams,
	INullable<AvlNet.PDF417Code> outPDF417Code,
	NullableValue<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 code is being detected.
outPDF417CodeAvlNet.INullable<AvlNet.PDF417Code>Found PDF417 code. This parameter cannot be null.
outAlignedRoiAvlNet.NullableValue<AvlNet.Rectangle2D>Input ROI after transformation (in the image coordinates). Can be null to skip this parameter calculation.

Remarks

In inCodeParams the parameter MinModuleSize should be more or equal to 3. For values less than 3 it is not guaranteed, that ReadSinglePDF417Code will process code properly.
