How to read bmp files from DRF0664 for display

Hi,

I have a DFR0664 tft lcd display and I'm trying to read a bmp off an SD card. I'm not sure how to get a pointer to the bmp and the documentation at GitHub isn't much help there. The readme at GitHub says there's supposed to be a tutorial video but there's no video on the page and no link to an external one; I couldn't find the video on the YouTube channel either. Can someone point me in the right direction?

Cheers,

John
