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). fn_DrawRow is used for drawing the bars, see BCSetFuncDrawRow() fn_DrawBar is used for drawing the bars, see BCSetFuncDrawBar() fn_DrawText is used for drawing the human readable text, see BCSetFuncDrawText() 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: ERRCODE  ErrOk (0) in case of success. Non-zero if error occurred.
