Detailed Description

Enumeration Type Documentation

enum TxCVC_BC_DIRECTION

This data type defines constants for the possible orientations in which a barcode may occur.

Related Topics:

DecodeDirection Property

Enumerator:

CVC_BC_OMNI	The barcode may be present in any orientation. 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 TxCVC_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 TxCVC_BC_DIRECTION to one of the other adjustments.

enum TxCVC_BC_DM_EX_TYPES

Expanded Data Matrix symbologies (Data Matrix, 2-D Pharmacode and dotted Data Matrix).

DataMatrixExTypes Property
TeachDottedMatrix Method

Enumerator:

CVC_BC_DM_EX_DATAMATRIX	The normal Data Matrix code will be read as usual. The remain Data Matrix parameters have no consequence for reading the code.
CVC_BC_DM_EX_2D_PHARMACODE	A 2-D Pharmacode will be expect. The colour bars around the code will be proved. If CVC_BC_DM_EX_2D_PHARMACODE is selected the properties DataMatrixBar1 to DataMatrixBar8, DataMatrixThreshold and DataMatrixExpanded have to be set correctly. The 2-D Pharmacode is a own type and will be issue as the type CVC_BC_2D_PHARMACODE in the result.
CVC_BC_DM_EX_DOTTED_DATAMATRIX	A dotted Data Matrix code can be read. If CVC_BC_DM_EX_DOTTED_DATAMATRIX is selected the properties DataMatrixContrastMin, DataMatrixModulwidth, and DataMatrixQuietzone have to be set correctly. Remark: If the property DecodeDirection is CVC_BC_SMALL_CODES the Barcode library don't read dotted Data Matrix codes. To read dotted Data Matrix codes set the DecodeDirection to one of the other adjustments.
