Re: Graphics contrast

Hi everyone,



I have updated the description of the Information graphic contrast page:

https://www.w3.org/WAI/GL/low-vision-a11y-tf/wiki/Informational_Graphic_Contrast_(Minimum)#Description



I checked the pixel size of stroke/line for 24px text, which is essentially 2.5 pixels. Because text is anti-aliased, it is sort of 2px solid, but often 3 or 4 pixels wide including the aliasing (the semi-transparent pixels). There is an example in the description.



I think 3px is a good compromise size for this purpose.



I still need to go through the examples to really test it out, but it’s getting there. (And thanks for the copious links Laura, are you a librarian by trade?!)



Cheers,
