ERRCODE _stdcall BCDrawCB	(	t_BarCode *	pBarCode,
		HDC	hDC,
		RECT *	pRectBounding
	)

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]	pRectBounding	Bounding rectangle (bar code size). If hDC is NULL, the unit is [0.001 mm]. The coordinates are transformed to an origin of (0,0).

Return values:

ERRCODE

ErrOk (0) in case of success. Non-zero if error occurred.
