# WolfChart v1.4
2017-01-25 02:22:04 -05:00
by Ballantyne de Wolf and Offspring Digital
This is professional optometrist/optician/ophthalmologist tool for measuring visual acuity. I cannot be used safely by the general public.
If you have any concerns about your vision or eyes, consult a qualified professional.
Now that's out of the way, the objectives are:
1. Clinically relevant, scientifically supported visual acuity measurement in the widest possible range of clinical settings
2. Open source with GNU licence
3. Can be used on a wide variety of screen hardware
3. Customisable optotypes and alphabets to come in version 2

- improved consistency of svg elements to use only filled paths and polygons, no strokes.
- improved implementation of rgba to permit overlapping elements - opacity is now applied to the whole svg element, not its child elements
- larger, more readable VA labels
- shortcut keys validated as unique
- scoreBox label element click/tap masks that line
