I have suggested they do so, but Google has provided no feedback on the suggestion. Now there is a chance to get Google to publicly address the issue. Slashdot will be "interviewing" Craig Silverstein, the Director of Technology for Google. Here is a link describing the interview, plus suggested questions submitted by slashdot readers. http://slashdot.org/article.pl?sid=02/06/20/0317220 I posted a suggested question, asking when Google will index PNG images. http://slashdot.org/comments.pl?sid=34509&cid=3738713 If my post gets replies, moderators are more likely to see it. The 10 highest-scored questions will be passed on to Craig. Currently there are no replies, but moderators have given it +2 points ("interesting"), making the total score +3. +5 is as high as a post can get. The +3 score puts my question in the upper middle of the pack of 100's of potential questions. Please consider reading my post, and, if interested, making a reply. I hope you favor the idea of searchable PNG images. Even if you don't, you might reply intelligently, hoping to persuade any moderator not to bump the score. Having Google begin indexing PNG images will be another step to full acceptance.

Thank you for your time. Unless that's covered in the HTML 4.x spec, I think it's an open question. In general I think the correct thing to do is to honor the transparency, blending it against the table/cell background color, the page background color, or the default background color (usually white or 75% gray), in order of preference (i.e., use the first one that exists, as with OBJECT). But some might also argue that if the PNG has a specified background color (bKGD) and the table/page _doesn't_, then you should blend against that color. Even aside from correctness, you're going to find a whole spectrum of behavior; NN 4.x doesn't do transparency at all, MSIE/Win doesn't do 32-bit transparency, many browsers use binary (thresholded) transparency, and not all of those that do full blending do it correctly for all PNG types. See http://www.libpng.org/pub/png/pngapbr.html for notes on variability. -- Greg Roelofs newt@pobox.com http://pobox.com/~newt/ Newtware, PNG Group, Info-ZIP, AlphaWorld Map, Philips Semiconductors, ... -- Send the message body "help" to png-list-request@ccrc.wustl.edu From owner-png-list@ccrc.wustl.edu Thu Jun 27 01:24:51 2002 Received: from viruswall.ccf.swri.edu (viruswall.ccf.swri.edu [129.162.252.34]) by swrinde.nde.swri.edu (8.9.3/8.9.3) with ESMTP id BAA13943; Thu, 27 Jun 2002 01:24:51 -0500 (CDT) Received: from mailhub.ccf.swri.edu (localhost [127.0.0.1]) by viruswall.ccf.swri.edu (8.10.2+Sun/8.10.2) with ESMTP id g5R6OmV24307; Thu, 27 Jun 2002 01:24:48 -0500 (CDT) Received: from ccrc.wustl.edu (dns.ccrc.wustl.edu [128.252.169.100]) by mailhub.ccf.swri.edu (8.11.2/8.11.2) with ESMTP id g5R6OkK15680; Thu, 27 Jun 2002 01:24:46 -0500 (CDT) Received: (from majordom@localhost) by ccrc.wustl.edu (8.11.6+Sun/8.11.6) id g5R6OV206036; Thu, 27 Jun 2002 01:24:31 -0500 (CDT) X-Authentication-Warning: ccrc.wustl.edu: majordom set sender to owner-png-list@ccrc.wustl.edu using -f Received: from a.smtp-out.sonic.net (a.smtp-out.sonic.net [208.201.224.38]) by ccrc.wustl.edu (8.11.6+Sun/8.11.6) with SMTP id g5R6OUO06032 for ; Thu, 27 Jun 2002 01:24:30 -0500 (CDT) Received: (qmail 24093 invoked from network); 27 Jun 2002 06:24:30 -0000 Received: from ultra.sonic.net (208.201.224.22) by a.smtp-out.sonic.net with SMTP; 27 Jun 2002 06:24:30 -0000 Received: from sonic.net (newbolt [208.201.242.18]) by ultra.sonic.net (8.11.6/8.8.5) with ESMTP id g5R6OUF12176 for ; Wed, 26 Jun 2002 23:24:30 -0700 X-envelope-info: Received: from newbolt.sonic.net (IDENT:roelofs@localhost [127.0.0.1]) by sonic.net (8.12.1/8.12.1) with ESMTP id g5R6OTAa007594 for ; Wed, 26 Jun 2002 23:24:29 -0700 Received: (from roelofs@localhost) by newbolt.sonic.net (8.12.1/8.12.1/Submit) id g5R6OT14007593 for png-list@ccrc.wustl.edu; Wed, 26 Jun 2002 23:24:29 -0700 Received: from nicemice.net (arwen.CS.Berkeley.EDU [128.32.46.192]) by ccrc.wustl.edu (8.11.6+Sun/8.11.6) with ESMTP id g5QLAAO02771 for ; Wed, 26 Jun 2002 16:10:10 -0500 (CDT) Received: from amc by nicemice.net with local (Exim 3.35 #1 (Debian)) id 17NK3D-0000nG-00; Wed, 26 Jun 2002 14:10:07 -0700 Date: Wed, 26 Jun 2002 21:10:07 +0000 From: "Adam M.

When in > this situation, does the browser disregard transparency? I don't know what actual browsers do, but I know what the PNG spec recommends: When displaying a PNG image with full alpha channel, it is important to be able to composite the image against some background, even if it's only black. Viewers that have a specific background against which to present the image (such as Web browsers) should ignore the bKGD chunk, in effect overriding bKGD with their preferred background color or background image. So I think the correct behavior for a web browser would be to composite the image against their default background color, then overlay the contents of the table on top of the image. But as I said, I don't know what browsers actually do. I'd actually be surprised if any of them do what I've described. I think this is sufficiently subtle scenario that web page authors might want to avoid using transparent images as backgrounds. AMC -- Send the message body "help" to png-list-request@ccrc.wustl.edu
