ReadPharmaCode
Detect and interpret a pharma code within the provided image.
Can be canceled by Watchdog.
Can use available TwinCAT Job Tasks for executing parallel code regions.

Description |
|---|---|---|---|
|
hrPrev |
|
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipSrcImage |
|
Source image (1 channel (all element types) or 3 channel with elements of type TCVN_ET_USINT, TCVN_ET_UINT or TCVN_ET_REAL (3 channel input is expected to be RGB and internally converted to Gray)) | |
|
ipDecodedData |
|
Returns the decoded code (ContainerType_Vector_String_SINT) | |
|
pipContours |
nullptr |
Returns the code positions as contours (optional, set to 0 if not required; ContainerType_Vector_Vector_TcVnPoint2_DINT) | |
|
nCodeNumber |
LONG |
1 |
Number of pharma codes that should be detected within the provided image (currently only 1 supported). |
|
nMinBarNumber |
SHORT |
4 |
Minimal number of (dark) bars that codes must have. |
|
pipAngles |
nullptr |
Returns the clockwise code rotation angles (optional, set to 0 if not required; ContainerType_Vector_REAL) |
