Notes from UDS Lucid discussion:

Symbolic icons

In karmic, we used '-panel' to signify icons meant for 'symbolic' icons (monochrome)

Other places we want simple, mostly-monochrome icons:

• Software Center search magnifying glass icons (vs. more complex search icon elsewhere)
• Clear-text-field icon (vs. more colorful, 3-D clear icon in toolbars etc)
• List-view header icons (?)
• Either side of a slider (e.g. Zoom Out / Zoom In in F-Spot)
• Chromium uses all custom icons by default just so that its toolbar can be all monochrome
• etc

Proposal is to use a -symbolic namespace

• themes can support it if they want to, otherwise it will fall back to the non-symbolic version

What about icons working on both white and black backgrounds?

• A separate namespace means that toolkits can treat the icon colors differently.
  • But applications don't always know what the background color is

Solved for text by using (e.g.) text[NORMAL] or fg[NORMAL]. When drawing icons with code, we can use cairo with foreground color.

Actions

• Need to define certain names that will be colored by renderers
  • Define a name for say, the red in the battery icon (a 'warning' color), that can be passed into rsvg
• implement named color handling in rsvg
• Make sure that panel-theme inheritance works correctly (some themes theme the panel differently, like Dust)
• Add (Single-paragraph?) addendum to the icon naming specification
• Write a reference on how to create SVGs that use the named color

perl script in icon-flow to replace a certain color with text[NORMAL]

Animations

We don't have a good story for it

• apng doesn't have good tools
• mng isn't well supported

Need some way of animating SVGs

• could be slices like the faux-animated PNGs we use now
