ReadSingleBarcode_Deprecated

Basic

Module: Barcodes

Detects and recognizes a single barcode in the input image.

Applications

To be used for basic linear barcode reading applications.
Name Type Range Description
Input value inImage Image Input image
Input value inRoi Rectangle2D* Region of interest
Input value inRoiAlignment CoordinateSystem2D* Adjusts the region of interest to the position of the inspected object
Input value inBarcodeFormat BarcodeFormat* Format of the barcode
Input value inMinGradientLength Real 0.0 - Minimal gradient length of edge pixels used for detecting barcodes
Input value inBaseBarWidth Integer 1 - Estimated width of the thinnest bar
Input value inDetectionScanCount Integer 1 - Number of scan lines used in detecting barcode
Input value inReadingScanCount Integer 1 - Number of parallel scans run until first successful read
Input value inScanWidth Integer 1 - Width of the single scan
Input value inMinStrength Real 0.0 - Minimal strength of an extracted edge
Input value inSmoothingStdDev Real 0.0 - Standard deviation of the gaussian smoothing applied to the profile extracted in each scan
Input value inPolarity Polarity Specifies whether code is darker or brighter than the background
Output value outBarcodePosition Rectangle2D? Position of the found barcode
Output value outDecodedText String? Decoded barcode content or nothing if all of the scans failed
