what about taking the occasion and changing to the not-so-patent-ridden png format ?

I remember reading recently that the patent finally expired earlier this year. Does anyone know if that's correct? Jonathan

The LZW patent in question expired in the US this Summer. But the patent only applies to generation of GIFs, not reading. So it's only the one person who created the GIF that would have needed a license. There are still other countries out there that have the patent active though.

Thanks for clarifying this. I was hoping the expiration of the LZW patent meant I could add LZW compression to the iostreams library. To you have more info on which other countries have issued patents on this algorithm which have yet to expire? Jonathan

... Although this patent has expired in the United States, patent searches by the FSF show that worldwide patents exist until 2006. If you must have a patent free version of the library, please look into libungif as a suitable replacement.

So perhaps you could ask them...

Thanks. Maybe I can add the code now, but with BOOST_STATIC_ASSERT(__YEAR__ >= 2006); ;-) Jonathan

Is it equally well supported by Internet browsers?

It looks fine in mozilla 1.4.1. konqueror (3.1.4-7 Red Hat (Qt: 3.1.2)) displays an additional single line of dots along the very bottom of the image. Angus

Hmm, that's not good. I just double-checked, and as far as I can tell the image itself is totally fine. I guess unless somebody knows how to fix this (and willing to do it), I'm going to stick with the old GIF.

I can't tell you what was wrong with your png, but after I loaded your file into The Gimp and exported it again as png, Konqueror does not show the garbage underneath anymore. (As a nice side-effect, the file became smaller: 6.8KByte instead of 8.1KByte.) You can download the new file from <URL:http://www.cdc.informatik.tu-darmstadt.de/~cludwig/boost_logo2.png>.

Done now. All duplicate copies of "c++boost.gif" file in various subdirectories removed; links are adjusted to point to the new master image. "inspect" tool modified to report, among others, broken image/css links.

Nice! Thanks for going through all that work! --Beman

Seems like there is something slightly amiss. Netscape 7 on Win98 doesn't like it and Konqueror 3.2 displays a funny line on the bottom. But given the relative market share of these browsers you might suspect a software bug -- although the Konqueror result is a bit suprising...

I converted the image using Photoshop, which I more or less trust. If somebody wants to give it one more try using something else, please be my guest!

Mandrake Linux 10 recent versions of browsers: (sorry too lazy to track all them all down) FireFox -- good. Epiphany -- good. Galeon -- good. Konqueror (V3.2.0) -- small line displays across the bottom.

Win98 IE 6.0.2600.000 -- good FireFox -- good Netscape 7 -- Gecko/20020823 -- "cannot be displayed, because it contains errors."

WinXP -- Service Pack2 FireFox -- good IE 6.0.2900++ -- good

Looks good in links2. w3m doesn't seem to recognize the transparency and renders the text "Boost" and the background, including the grid lines, except for those in the centre of the image, in black. The "C" partly is surrounded by a thin white line. Other parts of the "C" are not separated from the (black) background. (The gif looks fine, so this is not a general incapability of w3m to display transparency) Regards, m

Ultimately, it would be better to produce vector graphics version of the logo -- imagine, for example, putting the logo in the printed documentation. However, this can only be done by the person who created the original logo, and might be impossible if there's no vector version of background.

But it wouldn't be much use for the online documentation because most browsers have poor support for vector graphics... However, I agree that it'd be nice to have the original vector graphic if one exists. Cheers, Matt

Aleksey, if one of the reasons to replace this file turned out to be the undefined legal status of gifs,

A very secondary one; it was just too good of an opportunity to pass up; I was to do all the same work anyway.

then presumably the same holds true for google_logo_40wht.gif ? I attach a png version of same, converted using The Gimp which appears to have done a fine job with c++boost.png.

Since it's referenced from the main page only (and it's on the main page), I guess I can replace this one as well. Note though that there are many more GIFs in Boost buried away in various libraries' documentation, so this by no means gets rid of them. Thanks, though! -- Aleksey Gurtovoy MetaCommunications Engineering
