python script for gfx hat (LCD for raspberry)

Hi,

well, you'll get something displayed indeed - but you may get unexpected results. You still use a colored picture, but only use the 8bit representing the R (red) channel assuming the JPG is stored with RGB value. So if by incident your JPG has on all pixels on red, you won't see anything.

I still highly recommend to convert your image object into one having grey shades only, where each pixel is represent by a single 8bit value.
