These days anti-aliasing uses gray scale pixel values on displays with high pixel counts.
I'd like to take a step back in time and learn what is available for anti-aliasting or at least improving the quality of curved lines and fonts drawn on bindary (on/off) 1-bit displays, such as these low cost OLED displays shown below.
I don't know if the procedure would be called anti-aliasing, or something else. Ideally an explanation or a link/reference to a mathematical procedure or algorithm would be most helpful, or if something exists in Python, that would be great as well.
PIL, the Python Image Library is wonderful but I have a hunch it is mostly useful for gray scale or RGB continuous tone images rather than binary 1-bit images.
See for example the question Drawing multilingual text using PIL and saving as 1-bit and 8-bit bitmaps, where PIL turned this gray scale image:
into this 1-bit binary image:
and similar things would happen if I drew circles in PIL and then converted to 1-bit. The antialiasing is designed for continuous tone display, and so the subsequent thresholding just makes a mess.
