Myndex / SAPC-APCA

APCA (Accessible Perceptual Contrast Algorithm) is a new method for predicting contrast for use in emerging web standards (WCAG 3) for determining readability contrast. APCA is derived form the SAPC (S-LUV Advanced Predictive Color) which is an accessibility-oriented color appearance model designed for self-illuminated displays.

Hi Bruce @bruce-usab ... Perhaps "SampleATgdb" I'll work on that... the example texts I tend to use like "&IcyATOMsizedgap" or "AuxTextgadby" are chosen because they have an assortment of glyphs that show you most of what you need to know about a font design: easy to measure cap height and x height, descenders and ascenders, and design class ("ag" being two critical glyphs for classification).

I'll work on the bug report — I'm still investigating the depths of the Chrome rendering problem.

As for picking own fonts: very easy for anyone coding it for their own use, and probably not too hard for adding it as a feature. The reason for the fonts that are set as samples is that they all have all weights available. Most fonts don't, so I'd need to create a way to show samples only in the weights available for a font, and that's a bit more work. Will add it as a feature request.

Closing this only because there is going to be a new repo(s) for all Myndex created TOOLS and this repo is for discussion and issues with the underlying math, models, and algorithms. Third party developers are taking the bull by the horns and incorporating APCA all over now....
