)

Parameters

inImage: Type: AvlNet.Image
Input image
inRoi: Type: System.Nullable<AvlNet.Rectangle2D>
Range of pixels to be processed, or null.
inRoiAlignment: Type: System.Nullable<AvlNet.CoordinateSystem2D>
Adjusts the region of interest to the position of the inspected object, or null.
inAllowRectangular: Type: System.Boolean
Enables detecting rectangular Data Matrices
inCodeType: Type: AvlNet.DataMatrixCodeType
inCodeColumnCount: Type: System.Nullable<System.Int32>
Optional width of a Data Matrix, or null.
inCodeRowCount: Type: System.Nullable<System.Int32>
Optional height of a Data Matrix, or null.
outDataMatrix: Type: System.Nullable<AvlNet.DataMatrix>
outAlignedRoi: Type: AvlNet.Rectangle2D
diagValues: Type: AvlNet.Image
Image of decoded Data Matrix used by the reading algorithm

Description

This filter is a composition of DetectDataMatrices_Deprecated and RecognizeSingleDataMatrix_Deprecated filters.

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

DataMatrix on blurry image.

Low quality DataMatrix code.

DataMatrix on chip.

Rectangular DataMatrix code.
