Returns the optimal size of a bitmap for given bar code settings.
Returns the optimal size of a generated bitmap based on given bar code settings.
- Note:
- This function calculates the bar code size for a rotation of 0 degrees.
-
If a quiet zone is set, it is considered automatically by GetOptimalBitmapSize. But note that only quiet zones given in modules or pixels can be handled. The other units lead to an error because a device context would be needed for a proper bitmap size calculation. If you apply the results for a rotated bar code of 90° or 270° you have to exchange width and height.
- Parameters:
-
| [in] | pBarCode | Pointer to barcode structure. |
| [in,out] | pRect | [in] The size of the bounding rectangle (for barcode orientation of 0 degrees). [out] The size of the optimal bitmap. |
| [in] | nScaleX | horizontal scaling factor. |
| [in] | nScaleY | vertical scaling factor. |
- Return values:
-
| ERRCODE | ErrOk (0) in case of success. Non-zero if error occurred. |
