The fonttool.py and imgtool.py files help create C header files with bitmaps from jpeg files. Files generated using them are in the main/sprites diretory.
The offsets for imgtool.py are relative to the 800x480 canvas of the e-paper display.
To use the fonttool.py, place all the JPEG files containign the glyphs in the same directory as the fonttool.py and run the fonttool program specifying the destination file name and the font size.
