ERRCODE BCDrawCB ( t_BarCode pBarCode,
HDC  hDC,
RECT *  pRect 
)

Callback version of barcode draw function.

Call this function instead of BCDraw() if you want to use your own drawing routines (e.g. for generating a barcode on special devices or in special output formats).

Note:
BCDrawCB() can be used only with a developer license. Sample code is available on request: support@tec-it.com

Call-backs are disabled in the demo-version of TBarCode. If you need to try it please contact TEC-IT for a temporary license key.

Parameters:
[in] pBarCode Pointer to barcode structure.
[in] hDC Device context handle (optional, Windows only).
[in] pRect Bounding rectangle. If hDC is NULL, only the size of the rectangle is used. The coordinates are transformed to an origin of (0,0).
Return values:
