RecognizeMultipleDataMatrices_Deprecated
| Header: | AVL.h |
|---|---|
| Namespace: | avl |
Extracts information from multiple Data Matrix codes located at the specified positions.
Syntax
C++
void avl::RecognizeMultipleDataMatrices_Deprecated ( const avl::Image& inImage, const atl::Array<avl::Rectangle2D>& inDataMatrixPositions, avl::DataMatrixCodeType::Type inCodeType, atl::Optional<int> inCodeColumnCount, atl::Optional<int> inCodeRowCount, atl::Array<avl::DataMatrix>& outDataMatrices, atl::Array<atl::Conditional<avl::Image> >& diagValues )
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.
