Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | const Image& | Input image | |||
inDataMatrixPositions | const Array<Rectangle2D>& | Candidates for Data Matrices | |||
inCodeType | DataMatrixCodeType::Type | ||||
inCodeColumnCount | Optional<int> | 1 - 160 | NIL | Optional width of Data Matrix | |
inCodeRowCount | Optional<int> | 1 - 160 | NIL | Optional height of Data Matrix | |
outDataMatrices | Array<DataMatrix>& | ||||
diagValues | Array<Conditional<Image> >& | Images of decoded Data Matrices used by the reading algorithm |
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.
