DOUBLE BCGetModuleWidth ( t_BarCode pBarCode,
LPRECT  pRect,
HDC  hDC,
e_MUnit  eUnit 
)

Returns the module width.

Returns the computed module width for a given device context with respect to encoded data, check-digits, subset and other barcode parameters. You can specify the unit, which should be used for the return value.
hDC can be NULL. In this case the bounding rectangle must be specified in 1/1000 mm. The measurement units are:

  • eMUDefault ... logical units of the given device context.
  • eMUMM ... millimeters
  • eMUPixel ... pixels if device context is given, otherwise points (= 1/72 inch)
    Note:
    Call this function after BCCreate()
    Parameters:
    [in] pBarCode Pointer to barcode structure.
    [in] pRect Bounding rectangle.
    [in] hDC Device context handle.
    [in] eUnit Measurement unit.
    Return values:
    LONG Module width
