Bug 143476 – [GTK] Web Inspector: Optimize SVG images

• Component: Web Inspector
• Status: RESOLVED FIXED

[Andres Gomez Garcia]

GTK's own SVG images for the WebInspector have a lot of unneeded XML (unused attributes, tags, etc) generated by Inkscape.

We would like to slim them down.

Inkscape has some own methods to do so:

There are, also, a number of alternative tools that could help in this task:

I'm finally using a customized script which mainly makes use of the scour tool (http://www.codedread.com/scour/)

This customized script can be found at:

The original SVG files that I used to create material can be found at:

Awesome! This is a real improvement on the readability of the SVGs!

A lot of these have style attributes that I don't think apply. For example here: text-transform and text-indent. Do they apply if this is just a path without text?

Here is another one that is confusing. "enable-background:new". I don't think WebKit supports that, so it can probably be removed from all these SVGs.

You are right. Those are dead styles from some previous work with text, until I transformed it into a path. Clearly, we still can do the SVG simpler.

Same than above. I suppose, this is some dead style from Inkscape.

I will open a new bug to further optimize the SVGs and keep checking the available tools to automatize this.

Thanks for your comments, Joseph!
