icon_states in the browser

I can't find a way to display different icon_states of dmi files in the browser.

<IMG CLASS=icon SRC=\ref[icon] ICONSTATE='[icon_state]'>
is supposed to be the equivilent of \icon[src] in the text area, but does not work in the browser. Nor does 
<IMG SRC=[icon] ICONSTATE='[icon_state]'>



        var/image/I = image(icon,src)
        usr << browse_rsc(I)
        var/html = "<IMG SRC=[I]>"

gives a bad resource error on the browse_rsc() line, and predictably gives a broken image link in the browser if the browse_rsc() line is removed.
        var/icon/I = new(icon,icon_state)
        usr << browse_rsc(I)
        var/html = "<IMG SRC=[I]>"

also produces a broken image link.

(Yes, usr is used properly in the above snippets. The original snippet displayed icons in their default icon_state.)

I'm not too sure about this, but:

obj
    images
        someimage
            icon = 'someicon.dmi'
            icon_state = "some icon state"

mob
    verb
        showicon_state()
            var/someicon = /obj/images/someimage
            usr << browse_rsc(someicon,"someimage.dmi")
            usr << browse("<img src=someimage.dmi>")


It's not tested, just a guess, worth a try =P

No, that doesn't work.

I know it's something like that, I've done it before; I'll do a little testing later.

You're setting someicon to a type path; that will never work in browse_rsc().

I tried several varieties in the same theme. Creating a new instance of the obj, sending the icon to the browse_rsc, and using the obj in the IMG tag seemed most likely to work, but it doesn't (with or without a \ref text macro.)

You're close on that, but what you really need is /icon, not /image. With /icon you can strip an icon down to one state at creation time. Although in most cases you'd then have to use fcopy_rsc() to use the /icon, browse_rsc() has been set up in such a way that it knows an /icon should be converted to a .png.
var/icon/ic = new(icon,icon_state)
usr << browse_rsc(ic,"[ckey(name)].png")
var/html = "<IMG SRC='[ckey(name)].png' WIDTH=32 HEIGHT=32>"

You can use .dmi as the file name too. There was a time when BYOND cared which one you used, because otherwise it didn't convert correctly; the image converted via browse_rsc() is a PNG format either way.

The reason, incidentally, that the text-window format doesn't work in the mini-browser is that the text window is basically displaying HTML on its own, whereas the mini-browser uses IE. IE doesn't understand BYOND's special syntax for icons.

That works perfectly. Thanks, Lummox! Using an icon was one of the methods I tried, but I didn't assign a filename in the browse_rsc() and addressing it directly as I didn't work.

Yes. I realized that, but thought it was worth a shot anyway. :)
