GDI drawing method.
Drawing bars by the rectangle drawing function can lead to sub-optimal output quality. Therefore, TBarCode usually uses advanced drawing methods for more accurate barcodes. Due to incompatibilities with certain printer drivers the user can switch to the compatible mode or the dual mode instead.
- Enumerator:
-
| eDrawMode_Default |
Use the default GDI drawing method.
. |
| eDrawMode_Compatible |
Use the GDI rectangle functions to draw bars.
It may result in sub-optimal output quality, but is compatible to nearly all printers.
|
| eDrawMode_Advanced |
Use the advanced GDI draw mode.
This method results in the best quality but may not be supported by all applications or printers.
|
| eDrawMode_Dual |
A combination of the GDI drawing methods is used.
This method produces correct output in most applications and printers but might decrease drawing speed.
