RecognizeSingleDataMatrix_Deprecated


Header:FIL.h
Namespace:fil

Extracts information from the first correct Data Matrix code from among the specified positions.

Syntax

C++
 
void fil::RecognizeSingleDataMatrix_Deprecated
(
	const fil::Image& inImage,
	const ftl::Array<fil::Rectangle2D>& inDataMatrixPositions,
	fil::DataMatrixCodeType::Type inCodeType,
	ftl::Optional<int> inCodeColumnCount,
	ftl::Optional<int> inCodeRowCount,
	ftl::Conditional<fil::DataMatrix>& outDataMatrix,
	ftl::Conditional<fil::Image>& diagValues
)

Parameters

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

Description

The operation reads 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

RecognizeSingleDataMatrix_Deprecated results drawn onto an input image.
