The Adobe icon has the red trefoil with Adobe or Acrobat (older versions) on it, while the format icon has the red trefoil with PDF on it. Of course, the two icons were studied in a subtle way, in order to have the format icon different enough (full square instead of sheet of paper with folded angle, different text) but also similar enough (red trefoil and red colour) to associate them visually. > I thought that other products used a stylized version of the same icon > for recognition purposes, but I didn't know that it was standardized > in 1993 (presumably around the time that Adobe Acrobat 1.0 came out?) If I remember well, the pre-announcement happened at CeBIT 1992, and immediately after worldwide (Acrobat 1.0, still proprietary). One year later, during spring 1993, Adobe announced Acrobat 2.0 with a free PDF Reader and a proposal for an open format which could be implemented by third parties for free, provided they were using the format icon. > The implementation goals of the campaign do seem a bit fuzzy; in > particular, I'm not exactly sure what they wanted us to do with the > icons.

Unfortunately, there is a huge confusion between the Adobe software and the PDF format, as both use the same name (although one is proprietary software and the other a free open standard). > A different discussion, yes, but a related one (and I figured I'd > mention the idea before I forgot about it... :-) Right, I suppose that we can start discussing it now on the marketing mailing list - and find partners - to launch it at the conference in Milan (if possible). -- Italo Vignoli - [email protected] mob +39.348.5653829 - sip/jabber [email protected] skype italovignoli - hangout/jabber [email protected] -- To unsubscribe e-mail to: [email protected] Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/website/ All messages sent to this list will be publicly archived and cannot be deleted
