|---|---|---|---|
 |
inImage | Image | Input image |
|
inRoi | Rectangle2D* | Region of interest |
|
inRoiAlignment | CoordinateSystem2D* | Coordinate system for the region of interest |
|
inCodeParams | PDF417CodeParams | Specification of codes that can be detected |
|
inDetectionParams | PDF417DetectionParams | Specification of the way the code is being detected |
 |
outPDF417Code | PDF417Code? | Found PDF417 code |
|
outAlignedRoi | Rectangle2D | Input ROI after transformation (in the image coordinates) |
Hints
If code is not detected, try to use ResizeImage on it before processing with ReadSinglePDF417Code.
Remarks
In inCodeParams the parameter MinModuleSize should be more or equal to 3. For values less than 3 it is not guaranteed, that ReadSinglePDF417Code will process code properly.
