◆ BCSetDPI()

ERRCODE BCSetDPI ( t_BarCode pBarCode,
DOUBLE  dDPIHorz,
DOUBLE  dDPIVert 
)

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.
