Add fast text drawing API
bitbank2 opened this issue · comments
The GFX library is mostly based on drawing single pixels at a time to draw larger items. It allows simpler compatibility across different device types, but negatively affects performance. Would Adafruit accept a new set of functions for quickly drawing text? Faster text drawing would allow for some new use cases on serial displays such as demonstrated below. This demo is a file explorer which redraws the entire display to scroll/update the text.
The code uses the Adafruit_GFX/TFT API and is quite simple in the way that it optimizes text drawing. Let me know if you would accept the new feature and I'll create a pull request.
hiya sounds good on submitting a PR - as long as it doesn't break existing examples/functionality! lots of people are using this library so we are careful not to make things stop working.
