Issue 546206: Extension icons and MD

Reported by, Oct 21 2015 Project Member

Issue description

Extensions show icons on several UI surfaces which are now being changed for Material Design. The following is probably not an exhaustive list:

a) 16px icon (used as that extension's page favicon, used in search chip for  extensions like [1], etc.)
b) 19px page action icon
c) 19px browser action icon

Ideally in the MD world, the page and browser actions should be 16px while the search chip icon should be ~14px. We can scale down, but it won't look amazing.

Resize extension action icons to 16x16 in material design

Shrink the 19x19 extension action icons to 16x16
in top chrome material design so they match the
size and alignment of the other icons in the toolbar.

Could you please provide us with sample mocks so that we can verify the fix from test team end.

Comment 5 by, Dec 8 2015

This issue is not marked as Fixed, so there is nothing to verify at this time.

Handing over to Evan - is there anything left to do here?

Comment 7 by, Dec 11 2015

ah, there's still this one:

Another place to update the docs (should say "provide a 14x14") and another place to update calling code (should ask for 14 instead of 16).

Comment 8 by, Dec 11 2015

mmh these should be 16x16 as well no ? I'm using 16x16 icons in omnibox.

Comment 9 by, Dec 11 2015

But you're building padding into the icons. Here's what a 16x16 extension icon looks like in this chip.

Comment 10 by, Dec 11 2015

right, forgot it's in a chip :)

Comment 11 by, Dec 11 2015

ok so to be a bit clearer. Chrome chip icons are 16x16 but built-in with a padding.
for extension, you are right that they should deliver 14x14 to have a satisfying padding if they design the icon full-bleed.

A small question I have about this as an extension developer: how are you going to communicate the change to extension developers?

Just monkey-patching the documentation will catch developers unaware and unable to prepare in advance.

Chromium-extensions group is not an effective channel to reach developers, seeing the amount of noise there and how well did it go for toolbar redesign announcement.

Also, this already rolled out to Linux stable (was that intended?), see - so it's a bit late..

Comment 17 by, Jun 13 2016

This is a fair point.  We really do need a better way of communicating upcoming changes to developers.  chromium-extensions@ is better than nothing, but is very noisy.  Ideally, we'd at least be able to have a "What's new" and "Upcoming" section on the homepage of the documentation (and allow for people to subscribe to updates) or something similar.  There's been some discussions around how we can do this, but nothing's definitive yet.

Comment 18 by, Jul 19 2016

This change made the icons less legible.

1. A lot of extensions won't be updated to provide a 16px icon for the toolbar, so a distorted scaled-down version will be displayed. Many extensions simply work and are abandoned by their authors who moved on with their lives.

2. A 16x16px icon is too small, there's too little space to include nicely drawn details so many icons will look alike.

3. Since the icons are small and the overlayed infobadges cover parts of the icon there will be many users who have similar looking icons, so they'll have to examine carefully before clicking the one they need, losing their time.

Ironically, there exists such a page, but it has been abandoned since M44:

It would be great if the extensions/apps team could maintain something similar to

This change came through without updating developer documentation. I created an Issue for that, it would be great if it was triaged:
