The library supports drawing lines, shapes, text and images. All code is documented and there are demo examples. Tested on WaveShare 2.9inch e-Paper Display (B) 128x296 resolution using Wemos Lolin ESP32 Wrover.
Sample XGLCD fonts are included in the fonts folder. Additional fonts can generated from TTF fonts using a free utility called MikroElektronika GLCD Font Creator.
There are sample images in monocrhome (monoHMSB) and raw format. I’ve included a python app called img2monoHMSB.py in the utils folder to convert images in common formats such as JPEG and PNG to monoHMSB.
