uhm, vectorizing bitmap images sounds horrible to me :) from my experience with pdf2swf I can give the following advice concerning filesize:
- make sure all fonts are embedded in the pdf, otherwise all chars are converted to vector graphics which causes a major increase in filesize - complex vector objects (like illustrator images) can be very heavy and also cause the magazine player (whatever it might be) to slowdown because of all the vector calculations - resolution and size of input: preprocess the input pdf files; publishers for example deliver them with 300dpi but for magazine players in a browser you wont need more than 110dpi - tho afaik pdf2swf is downsampling them but I'm not sure how efficient it does this - you never know how many pages your magazines will have thus I recommend using a clever preloader like loading only the next couple of pages, on jumps load the next and the previous pages, stop loading if a video is played and so on. keep the users experience at a maximum. - all this has already been done several times by others. the best (as in most complete and crazy features like grouping and animating objects from generated SWFs, all kinds of media imports, export to CD version, web zip, ipad, iphone) solution I know is www.3d-zeitschrift.de (english version is here: www.3d-flip.com ) tho it is not a free solution and more for publishers directly. but there are open source players like www.megazine3.de hope that helped :) philip On Thu, Sep 1, 2011 at 8:03 PM, Michael Geary <[email protected]> wrote: > What is the nature of your PDFs?
