The Eclipse platform projects currently use mainly gif files which do not support a real transparency. We should switch to png files, wherever possible. This is supposed to be master bug for the different changes in the platform plug-ins including JDT.
Adding bug 432741 as "child" of this one. I thought there was another, more general bug, but since I could not find it, thought I'd at least document the relationship here. The "general" part of bug 432741 is the standard guidelines of http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html which says the "icon.xpm" file we specify for Linux is "supported for legacy" reasons, but ... png preferred, and svg optional ... and I think even those "guidelines" are pretty old -- and not sure if widely accepted as "standard" or not. So, can leave the "icon.xpm" file in our distributions, in case any "old" platforms need it ... but, but 432751 is "linux specific" and more so only tested on "Ubuntu", so if anyone has any RedHat or "HP" machines to test with that'd be great. I'm assume it makes "no difference" on those other platforms, but perhaps makes an improvement if someone is using some particular 'fancy' desktop.
Note for adopters: E4 stores a reference to the extension point contribution org.eclipse.ui.editors > editor > icon for each editor tab that is open when the workbench shuts down (bug 465456). Projects that switch to .png graphics need to keep the .gif versions for such icon contributions. Please mention bug 465456 in the comment of the commit that removes most .gif files but leaves a few around.
(In reply to Markus Keller from comment #2) > Note for adopters: Update (via bug 465456): Bundles need to keep the *.gif icons of values contributed in extension points: - org.eclipse.ui.editors > editor > icon (typically in /icons/full/obj16/) - org.eclipse.ui.views > view > icon (complete /icons/full/eview16/ folder)
I declare victory for this aggregator bug and we will solve remaining issues via separate bugs. Thanks again to Tony and all involved projects to make the transition possible.
