BCSetDPI

ERRCODE BCSetDPI ( t_BarCode *  pBarCode, LONG  nDPIHorz, LONG  nDPIVert   ) Sets user defined resolution. Sets output resolution to be used in bar code drawing / calculation functions. If not set (default), the resolution of the available device context is used (e.g. screen resolution or printer resolution). Can be used to estimate the quality of a bar code for a specific output resolution (BCGetQuality()). For other purposes this function should be used careful, because bar code dimensions can change unexpectedly. See also: BCGetDPIHorz(), BCGetDPIVert() Parameters: [in]  pBarCode  Pointer to barcode structure. [in]  nDPIHorz  User defined horizontal DPI (-1 ... reset to default). [in]  nDPIVert  User defined vertical DPI (-1 ... reset to default). Return values: ERRCODE  ErrOk (0) in case of success. Non-zero if error occurred.
