  EAN8()

  Default constructor

• SetXResolution

  void SetXResolution (int xres);

  The function sets the horizontal resolution of the output device.

  Parameters:

  xres

  [in] - The horizontal resolution of the output device.

• SetYResolution

  void SetYResolution (int yres);

  The function sets the vertical resolution of the output device.

  Parameters:

  yres

  [in] - The vertical resolution of the output device.

• SetNumber

  BOOL SetNumber (LPCTSTR pszNumber);

  The function sets the number which is drawn as the barcode.

  Parameters:

  pszNumber

  [in] - This is the number (7 or 8 digits) which is drawn as the barcode.

  Return value:

  This function returns TRUE if it could recognize passed parameters and FALSE if it failed.

• DrawBarCode

  void DrawBarCode (HDC dc,int x0,int y0);

  The function draws the barcode.

  Parameters:

  dc

  [in] - The output device context.

  x0

  [in] - This is the horizontal offset from the origin, left edge of barcode. The offset is measured in logical device units.

  y0

  [in] - This is the vertical offset from the origin, top edge of barcode. The offset is measured in logical device units.

• SetZoomFactor

  void SetZoomFactor (double factor);

  The function sets the zoom factor of the barcode. According to the standart it can be from 0.8 to 2.0.

  Parameters:

  factor

  [in] - The zoom factor.

• GetZoomFactor

  double GetZoomFactor ();

  Return value:

  The function returns the value of the zoom factor.

• SetLeadInAndLeadOutFlag

  void SetLeadInAndLeadOutFlag (BOOL bLeadInAndLeadOutFlag);

  The function sets the flag of leadings. If the flag is TRUE then the LeadIn and LeadOut blanks are drawn.

  Parameters:

  bLeadInAndLeadOutFlag

  [in] - The flag's value,TRUE or FALSE.

• GetLeadInAndLeadOutFlag

  BOOL GetLeadInAndLeadOutFlag ();

  Return value:

  The function returns the flag of the  LeadIn and LeadOut drawing.

• SetEdgeFlag

  void SetEdgeFlag (BOOL bEdgeFlag);

  The function sets the flag of the bottom edges drawing. If the flag is TRUE then the edges are drawn.

  Parameters:

  bEdgeFlag

  [in] - The flag's value,TRUE or FALSE.

• GetEdgeFlag

  BOOL GetEdgeFlag ();

  Return value:

  The function returns the flag of the edges' drawing.

• SetDrawTextFlag

  void SetDrawTextFlag (BOOL bDrawTextFlag);

  The function sets the flag of text drawing. If the flag is TRUE then the numbers (main and addon) are drawn.

  Parameters:

  bDrawTextFlag

  [in] - The flag's value,TRUE or FALSE.

• GetDrawTextFlag

  BOOL GetDrawTextFlag ();

  Return value:

  The function returns the flag of text' drawing.

• SetBackgroundFlag

  void SetBackgroundFlag (BOOL bBackgroundFlag);

  The function sets the flag of background drawing. If the flag is TRUE then the background behind barcode is drawn.

  Parameters:

  bBackgroundFlag

  [in] - The flag's value,TRUE or FALSE.

• GetBackgroundFlag

  BOOL GetBackgroundFlag ();

  Return value:

  The function returns the flag of background drawing.

• SetForegroundColor

  void SetForegroundColor (COLORREF color);

  The function sets the color of the barcode's foreground. The color can be calculated using RGB() macro.

  Parameters:

  color

  [in] - The color.

• GetForegroundColor

  COLORREF GetForegroundColor ();

  Return value:

  The function returns the color of the barcode's foreground.

• SetBackgroundColor

  void SetBackgroundColor (COLORREF color);

  The function sets the color of the barcode's background, if it is drawn. The color can be calculated using RGB() macro.

  Parameters:

  color

• GetBackgroundColor

  COLORREF GetBackgroundColor ();

  Return value:

  The function returns the color of the barcode's background.

• SetExactSymbolHeight

  void SetExactSymbolHeight (double height);

  The function sets the exact height of the barcode. It does not meet the standart, but often it is a useful feature.

  Parameters:

  height

  [in] - The height (in millimiters).

• GetExactSymbolHeight

  double GetExactSymbolHeight ();

  Return value:

  The function returns the exact height of the barcode, if it has been set.
