Returns drawing quality estimate of the barcode (in percent) (Windows only). 
TBarCode computes the expected barcode quality depending on the used output resolution. This value is a measure for the bar width aberration created by the output resolution of the device context (and therefore of the device itself). The higher the quality value - the better. 
- Note:
- WINDOWS only. 
- Parameters:
- 
  
    | [in] | pBarCode | Pointer to barcode structure. |  | [in] | hDC | Device context handle of output device. |  | [in] | pRectBounding | Bounding rectangle. |  
 
- Return values:
- 
  
    | LONG | Bar-code quality [0 (unreadable)...100 (perfect)] |
