The file libraries allow to save the screen or a window on a file, and to load it back into the frame-buffer.
There are three options:
- The BMP file option saves and loads a BMP file to and from the SD-card.
Everything is performed at run-time.
The header file on SD-card option saves a header file to the SD-card;
The header file on serial console option prints a header file on the serial console.
The header file needs to be included into an application at build-time and displayed at the next run-time.
|Method||BMP file||Header file||Serial console|

|Read from||SD-card||Header file||Header file|
The file operations on SD-card require the external SD library library.
Ensure the external SD-card library is installed and properly configured.
