On a Raspberry Pi Pico, I benchmarked a modified version of adafruit_bitmap_font's pcf reader which uses readinto instead of the existing code. My test font was a 72-point file created from Arial. This decreased the time to load all the ASCII glyphs from 4.9 seconds to just 0.44 seconds. While this attempts to support many pixel configurations (1/2/4/8/16/24/32 bpp; swapped words and pixels) only the single combination used by PCF fonts was tested. add fill_region and draw_line to bitmaptools 2021-03-10T17:37:27+00:00 Kevin Matocha kmatocha@icloud.com 2021-03-10T17:37:27+00:00 urn:sha1:85f0f07d51343bd67c1b2308bdfed192cc470549 Add bitmaptools module 2021-02-24T05:23:14+00:00 Kevin Matocha kmatocha@icloud.com 2021-02-24T05:23:14+00:00 urn:sha1:b7200286425363c430b7f4466c27e53ea67f7887
