| """ Experimental python script for converting a 3-colour bmp to a 2-colour bmp for use with 2-colour E-Paper displays.  |  | ||||||
| Please use at your own risk. |  | ||||||
|  |  | ||||||
| To use the converter, input a folder path containing the bmps that require converting (input folder) |  | ||||||
| and then specify an output folder for the converted bmps. |  | ||||||
| Lastly, replace the original bmp files with the converted ones and reboot to start the E-Paper software with the new bmps. |  | ||||||
| That's all |  | ||||||
