AVL.RecognizeMultipleDataMatrices_Deprecated(AvlNet.Image, AvlNet.Rectangle2D[], AvlNet.DataMatrixCodeType, int?, int?, AvlNet.DataMatrix[], AvlNet.Image[])

Extracts information from multiple Data Matrix codes located at the specified positions.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void RecognizeMultipleDataMatrices_Deprecated(
	AvlNet.Image inImage,
	AvlNet.Rectangle2D[] inDataMatrixPositions,

	int? inCodeColumnCount,
	int? inCodeRowCount,
	out AvlNet.DataMatrix[] outDataMatrices,
	out AvlNet.Image[] diagValues
)

Parameters

inImage
Type: AvlNet.Image
Input image
inDataMatrixPositions
Type: AvlNet.Rectangle2D
Candidates for Data Matrices
inCodeType
Type: AvlNet.DataMatrixCodeType
inCodeColumnCount
Type: System.Nullable<System.Int32>
Optional width of Data Matrix, or null.
inCodeRowCount
Type: System.Nullable<System.Int32>
Optional height of Data Matrix, or null.
outDataMatrices
Type: AvlNet.DataMatrix
diagValues
Type: AvlNet.Image

Description

The operation recognizes a DataMatrix code on the inImage.

The operation is capable of reading codes from images subject to perspective distortion.

Supported code types: ECC 200 and ECC 000-140.

Around datamatrix must be quiet zone. The minimum quiet zone is equal to the width of a module on all four sides. For applications with moderate to excessive reflected noise in close proximity to the symbol, a quiet zone of 2 to 4 module widths is recommended.

Examples

RecognizeMultipleDataMatrices_Deprecated results drawn onto an input image.
