| typedef intptr_t CVC_BC_CONFIG |
This data type defines a handle for a configuration (see chapter Configurations).
This type of handle is returned when the CvcBcCreateConfiguration
function is called. In the case of all other functions, such a handle is expected to be passed as a parameter.
| enum CVC_BC_DIRECTION |
This data type defines constants for the possible orientations in which a barcode may occur.
| Enumerator | |
|---|---|
| CVC_BC_OMNI | The barcode may be present in any orientation (for unidirectional). This also includes vertical and horizontal orientation. However, evaluation is somewhat faster if the orientation of the barcode is already known. Moreover, in the case of long narrow image objects, such as produced by line cameras for example, the specification of CVC_BC_OMNI is problematic. In such cases it is better to specify CVC_BC_FENCE or CVC_BC_LADDER. |
| CVC_BC_FENCE | The barcode is expected to occur in horizontal orientation i.e., it consists of vertical lines (and looks like a picket fence). |
| CVC_BC_LADDER | The barcode is expected to occur in vertical orientation i.e., it consists of horizontal lines (and looks like a ladder). |
| CVC_BC_BOTH | The barcode may be present in either vertical or horizontal orientation, but not in an angle of rotation of 45 degrees. |
| CVC_BC_SMALL_CODES | A small barcode is expected. If CVC_BC_DIRECTION is set to CVC_BC_SMALL_CODES the Barcode library don't read dotted Data Matrix codes. To read dotted Data Matrix codes set the CVC_BC_DIRECTION to one of the other adjustments. |
| enum CVC_BC_TYPE |
This data type defines constants for all barcodes which can be read using this library.
When a barcode is decoded using the function CvcBcDecodeBarcode, one of the column constants is entered in the type element of the structure CVC_BC_INFO. This makes it possible to determine the type of the read barcode if multiple barcodes are active.
