[Enhancement] Image borders #3121

Open rachelkang opened 2 years ago

rachelkang commented 2 years ago

Summary

Disclaimer: I'm not sure how feasible this is and have not looked into it at all yet!

Many images, especially ones consisting of multiple colors and a transparent background, do not have sufficient color contrast against their background. This leads to a failure to meet accessibility requirements.

Images can easily be made more accessible (with regard to color contrast) by adding a single color border/outline that contrasts against the background. So, if we could introduce a property to enable image outlines/borders, that could be super helpful for accessibility.

Inspiration

I came across this when I had issues with images in my recipes app:

accessible images borders

Intended Use Case

Making images more accessible

Workaround

Just use images that already have these accessible traits

We can accomplish this manually with Borders. So one option would be for that property to specify a contrast color, and we automatically wrap the Image in a Border of that color.

Would it be useful to have this for all controls, rather than just Image? I wonder if this something we want at the IView level, or maybe in the semantic properties.
