Please see bug 419588 comment 46. We should expose this media fragment to chrome callers only for now.

Boy do I wish we could just get rid of -moz-resolution entirely and take another approach. =\

How does this relate to e.g. image-resolution[1]? Couldn't find any doc for -moz-resolution … [1] http://www.w3.org/TR/css3-images/#the-image-resolution

Hi guys, I'm trying to write an add-on where I need to get the different sizes of the icon on the exe. So what I do right now (on winXP) is: var foxexe = FileUtils.getFile("XREExeF", []); var iconurl = "moz-icon:" + Services.io.newFileURI(foxexe).spec; which gives: * moz-icon:file:///C:/Program%20Files/Aurora/firefox.exe?size=16 * moz-icon:file:///C:/Program%20Files/Aurora/firefox.exe?size=32 but the size=16 one is very blurry, the size=32 one is good. could i use -moz-resolution to help me out here? i couldnt find any documentation anywhere thanks guys

Not really no. We don't have any built in ways to query the available sizes in a particular file. You could either iterate through a bunch of sizes and drawn them on canvases to get sizes, or you could write a parser in js (these files are pretty simple to read).

Thanks for the super fast reply man! I don't understand what's going on three. If I use drawImage to canvas with resize parameters it will come out really nicely anti-aliased on resize? I don't understand the need to iterate through the sizes, then next I don't know how to do that. :( I'm not sure what a parser is. Are you saying I can use moz-resolution but before I do I have to know the sizes? I thought a png or ico was only one size. If you can please help me answer these questions that would be so great!!

Also could you tell me how to use moz-resoloution please. Like what it does. Maybe I can get it to work. :)

(In reply to Seth Fowler [:seth] from comment #1) > Boy do I wish we could just get rid of -moz-resolution entirely and take > another approach. =\ As far as I can tell only three Firefox UI files and one add-on use it. B2G/gaia do not. Seems about as good a position we could wish for if we want to remove it.
