This is a python image converter specific for the E-Paper-Calendar
|
||||
on github by aceisace from the link below.
|
||||
(https://github.com/aceisace/E-Paper-Calendar-with-iCal-sync-and-live-weather)
|
||||
|
||||
It will convert the 3-colour .bmp's to 2-colour .bmp's so that they can be
|
||||
used even with the 2-Colour 7.5" E-Paper Display from waveshare.
|
||||
|
||||
Please use with caution. If the input and output paths are the same, the
|
||||
convertr will overwrite all .bmp files. It's highly recommended to make a
|
||||
backup of the entire 'Calendar" folder first.
