ReadMultiplePDF417Codes


Module: Datacodes

Detects and recognizes several PDF417 codes.

Name Type Description
Input value inImage Image Input image
Input value inRoi Rectangle2D* Region of interest
Input value inRoiAlignment CoordinateSystem2D* Coordinate system for the region of interest
Input value inCodeParams PDF417CodeParams Specification of codes that can be detected
Input value inDetectionParams PDF417DetectionParams Specification of the way the codes are being detected
Input value inAllowMultipleScales Bool Specifies whether codes of different module sizes are expected
Output value outPDF417Codes PDF417CodeArray Found PDF417 codes
Output value outAlignedRoi Rectangle2D Input ROI after transformation (in the image coordinates)

Hints

If codes are not detected, try to use ResizeImage on them before processing with ReadMultiplePDF417Codes.

Remarks

In inCodeParams the parameter MinModuleSize should be more or equal to 3. For values less than 3 it is not guaranteed, that ReadMultiplePDF417Codes will process codes properly.
