Load img from memory buffer

[SmoothWifi]

Hello,

thanks for that great job! I am trying to load img from buffer directly (for later OTA possibilities) but I don't know how to save the img (include img.h but how to convert them?) nor how to call them.
Any advice would be really aprreciated :)

Thanks!

I write the display buffer In my case 4000 bytes) to a file in a spiffs filesystem so it stays after reboot / OTA
