RecognizeBarcode_Deprecated
Header: | AVL.h |
---|---|
Namespace: | avl |
Module: | Barcodes |
Extracts information from a barcode located on the input image at a given position.
Applications: Most often used after a barcode detection filter.
Syntax
void avl::RecognizeBarcode_Deprecated ( const avl::Image& inImage, const avl::Rectangle2D& inBarcodePosition, atl::Optional<const avl::CoordinateSystem2D&> inBarcodePositionAlignment, atl::Optional<avl::BarcodeFormat::Type> inBarcodeFormat, const int inScanCount, const int inScanWidth, const float inMinStrength, const float inSmoothingStdDev, avl::Polarity::Type inPolarity, atl::Conditional<atl::String>& outDecodedText, atl::Conditional<avl::BarcodeFormat::Type>& outBarcodeFormat, atl::Optional<atl::Conditional<avl::Polarity::Type>&> outBarcodePolarity = atl::NIL, atl::Optional<avl::Rectangle2D&> outAlignedBarcodePosition = atl::NIL, atl::Array<avl::Segment2D>& diagScheduledScanSegments )

diagScheduledScanSegments | Array<Segment2D>& | Scheduled scan segments |
Optional Outputs
The computation of following outputs can be switched off by passing value atl::NIL
to these parameters: outBarcodePolarity, outAlignedBarcodePosition.
