Basic| Module: | Datacodes |
|---|
Detects and recognizes several PDF417 codes.
| Name | Type | Description | |
|---|---|---|---|
 |
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 codes are being detected |
|
inAllowMultipleScales | Bool | Specifies whether codes of different module sizes are expected |
 |
outPDF417Codes | PDF417CodeArray | Found PDF417 codes |
|
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_Deprecated.
Remarks
In inCodeParams the parameter MinModuleSize should be more or equal to 3. For values less than 3 it is not guaranteed, that ReadMultiplePDF417Codes_Deprecated will process codes properly.
