Calculates the layout for multiple barcodes.
Call this function before BCCreate() and BCDraw() if you want to render multiple barcodes. This function splits a barcode into multiple barcodes. It automatically determines the required number of barcodes and the layout, i. e. the number of rows and columns. - See also:
- BCCreate(), BCDraw(), BCSaveImage()
- Note:
- This function call is a must, when you want to render multiple barcodes!
- Parameters:
-
| [in] | pBarCode | Pointer to barcode structure |
| [in] | hDC | GDI device context. Only relevant for GDI output. |
| [in] | pRect | Bounding rectangle, specified in the current mapping mode (GDI) or in 1/1000 millimeter (PS, PCL, images). |
| [out] | pnRequiredWidth | Required width of bounding rectangle. 0 indicates that the required width could not be calculated. |
| [out] | pnRequiredHeight | Required height of bounding rectangle. 0 indicates that the required width could not be calculated. |
- Return values:
-
| ERRCODE | ErrOk (0) in case of success. Non-zero if error occurred. |
- Note:
- This function is only used in Multiple Barcodes mode.
