The Responsive Images WebCore fork!!!

This repository contains experiments in adding the <picture> element to WebKit's WebCore library.

It is based on Chromium's WebKit from 17/10/12.

Note: This is a work in progress. It does not (yet) represent a full implementation of the <picture> element specification. Please file any inconsistency with the specification as an issue.

Build instructions:

• Build Chromium like you normally would on Linux or [OSX] (http://code.google.com/p/chromium/wiki/MacBuildInstructions)
• If your time is precious, use Ninja
• Download the patch from here to your /tmp directory
• Apply the patch using (cd third_party/WebKit/Source/WebCore && patch -p0 < /tmp/picture_patch.txt)

Binaries:

• Ubuntu 64bit & OSX binaries can be found here

Test page:

Once you got your new binary, you can see <picture> in action [here] (http://demos.responsiveimages.org/)

What should be working:

• <picture><source src></picture> should work. The first source should be fetched by the PreloadScanner and then displayed when the element is parsed.
• <picture src></picture> prefetches and displays the resource. It overrides inner <source> tags if present.
• The media attribute should be working as expected for both the PreloadScanner and the actual parser.

What shouldn't be working (yet):

• The srcset attribute is not yet supported in either the PreloadScanner or the actual parser.
• The type attribute is not yet supported in either the PreloadScanner or the actual parser.
