Summary: IE CSS filters are broken Product: Wine Version: 0.9.21. Platform: All URL: http://brodierao.com/etc/wine/filters.html OS/Version: All Status: UNCONFIRMED Severity: normal Priority: P2 Component: wine-shdocvw AssignedTo: wine-bugs@winehq.org ReportedBy: dackze@gmail.com
With Wine 0.9.21 (and older versions), Internet Explorer's proprietary CSS "filter" property does not work. This is commonly used to provide alpha transparency for PNGs in IE6 and IE5.5 (IE4 supports it with different filter names). The URL in this bug report shows a very basic example of a CSS filter, but for an example of alpha transparency in PNGs, see http://webfx.eae.net/dhtml/pngbehavior/demo.html . More information can be found at MSDN: http://msdn.microsoft.com/workshop/author/filter/filters.asp .
I didn't see any interesting message with WINEDEBUG set to "fixme+all". I get the same gist of messages for any page, regardless of what CSS filters are present, but I can attach a log if necessary.
I also would like to say this is a fairly important feature for web designers and programmers. I implement web designs, which frequently employ advanced effects such as translucency, and not being able to test that without Windows is a bit of an annoyance.
Also, I'm not entirely sure if wine-shdocvw is the right component for this bug report, so forgive me if that's incorrect.
