I'm not much of a fan when it comes to animated images, mostly because they tend to eat up extra bandwidth (which is something that I don't have a lot of at home). # I'm rather sure .png images support transparency. It does, though IE and potentially Netscape 4.x have some issues with alpha transparency... but it may not be something to worry about. # Hmm, some .png images are much larger than their .jpg counterparts. # E.g. : #=20 # getstarb.jpg 26-Apr-2004 12:24 20k =20 # getstarb.png 26-Apr-2004 12:24 171k #=20 # That seems a bit exessive, but can hopefully fixed by using another # program for the conversion (or tuning some parameters). #=20 # How much space does the .png images use compared to the .gif/.jpg # versions ? Since PNG is a lossless format, you can crank up the compression level and not lose any details in the image (I think it just requires a bit more CPU cycles to decompress the image... but I could be really wrong there).=20 For instance, I've converted a copy of the "Powered by FreeBSD" GIF to PNG and the PNG version is a bit smaller: -rw-r--r-- 1 question wheel 5279 Jan 20 2003 powerlogo.gif -rw-r--r-- 1 question wheel 4957 Jan 20 2003 powerlogo.png IIRC, I used the gif2png port to do the conversion. The only JPEG file that I have for my site that I converted to PNG was done through GIMP. I'm not sure if or what port(s) are available for the JPEG->PNG conversion. # If a browser doesn't support .png today... well, I can live with not # supporting that browser then :-). heh... yeah, I wouldn't worry about many people browsing the FreeBSD websites using Sun's Java web browser that they had a while ago :) # Hmm, well if it's only the powerani.gif image that needs to be converted # then it sounds like MNG is better than nothing. <nods /> At least it will show that the project continues to push for open standards and open formats :) # At first I though it would be a bad idea to rename the diretory... but # the I had a look at the content of the diretory : #=20 # [simon@zaphod:gifs] du -ck . | tail -n 1 # 3680 total # [simon@zaphod:gifs] du -ck *.jpg *.gif | tail -n 1 # 3256 total # [simon@zaphod:gifs] du -ck *.png | tail -n 1 # 250 total #=20 # So it's the main part of the directory that needs to be replaced anyway, # so it wouldn't really hurt much (in wasted repository space) to rename # the directory at the same time as we convert the images. So, I'm also # for renaming the directory and 'img' seems as good a name as any to me. I was a bit nervous after I wrote the directory rename bit and after I sent out the message :D I like and use "img" since it's fairly neutral. --=20 Linh Pham question@closedsrc.org Webmaster and FreeBSD Geek http://closedsrc.org Apprentice Manager Editor and Writer http://www.daemonnews.org C++ is to C, as lung cancer is to lung | There is always one more bug. --0ntfKIWw70PvrIHh Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAjYjqwhofDeWkDMIRAu3mAKCztAZbuR3Ul20rlEUe3O021qoxxQCgocyS xRjZUCWTwjoRtfqBDxPBSAY= =FtaO -----END PGP SIGNATURE----- --0ntfKIWw70PvrIHh--
