Graphics.createCallback in Bangle.js 1 vs 2 | Vector Font | Font converter

You could potentially do something different: Have 2x 1bpp ArrayBuffer graphics, render to each, and then XOR them together.

I like that... that was the thought of how to update watch face in Bangle 1 with high frequency of events / the desire of (a) smooth sweeping hand (s). The issue is that keeping an. image in memory (buffer) all the time is a lot of memory. With a smart arrangement - diving the image up into quadrants (plus a few pixels for overlap) can cut the amount of working memory down to about a quarter (1/4, 25%).
