Hmm… I'm one of the developers of Diva. I noticed that you've been getting your files from the Internet Archive. They also have the full high-quality JPEG and JPEG2000 images available. http://ia600209.us.archive.org/6/items/acourseofreligio00gerauoft/ You could use those for Diva instead of the already-compressed PDF. Printing could still be handled by downloading the PDF, but if you just want to be able to view it online then I'd be happy to help you get Diva set up.

So this is awesome, does it in fact work with PDF's or not, and if not does anyone have any similar tools recommended for pdfs ap On 10/3/11 11:12 AM, Dave Caroline dave.thearchiv...@gmail.com wrote: Diva was announced here of 6th of June https://listserv.nd.edu/cgi-bin/wa?A2=ind1106L=CODE4LIBT=0F=S=P=27064 The clever part is you only send the visible part at the scale they are viewing so little excess bandwidth.

While I agree that Diva offers a really good on-screen reading experience (probably the best I've used so far), Archive.org itself offers a good one too. So, for the first book in Eric's list, http://www.archive.org/details/acourseofreligio00gerauoft the on-screen reader is at http://www.archive.org/stream/acourseofreligio00gerauoft I tried it out in my 3 year old, 2nd generation iPod Touch over the flakey campus WiFi and found that it displayed quite nicely. You have paging controls, but can also use touch gestures to scroll and pinch the page larger. Like Diva, it uses lazy loading techniques, so you don't have to wait until the whole document is available to start reading. Tom
Re: [CODE4LIB] opening a pdf file [diva]
It doesn't work with PDFs, since it needs to create a tiled TIFF image for each page. I don't know of anything similar for PDFs, since they're not really designed to render a portion of the document without downloading the entire thing. You can convert PDF pages to images, though... :) -Andrew On 2011-10-03, at 12:09 PM, Parker, Anson (adp6j) wrote: So this is awesome, does it in fact work with PDF's or not, and if not does anyone have any similar tools recommended for pdfs ap On 10/3/11 11:12 AM, Dave Caroline dave.thearchiv...@gmail.com wrote: Diva was announced here of 6th of June https://listserv.nd.edu/cgi-bin/wa?A2=ind1106L=CODE4LIBT=0F=S=P=27064 The clever part is you only send the visible part at the scale they are viewing so little excess bandwidth.

-Original Message- From: Code for Libraries [mailto:CODE4LIB@LISTSERV.ND.EDU] On Behalf Of Andrew Hankinson I don't know of anything similar for PDFs, since they're not really designed to render a portion of the document without downloading the entire thing. The linearized form of PDF is designed to do just that: permit a PDF viewer to display the first page while still downloading the rest of the document. The pdfopt utility, which I believe installs with ghostscript, will do this from the command line. Alternatively you can save a PDF with fast web view enabled in Acrobat Professional. There are surely other ways to create a linearized PDF, but those are the methods I've used. -AB -- Head, Digital Research Library University Library System University of Pittsburgh 7500 Thomas Blvd., Room 306 Pittsburgh, PA 15260 Phone: 412.244.7526 Fax: 412.244.7537
Re: [CODE4LIB] opening a pdf file [diva]
Another idea, if you are looking for an app-based rather than web-based reader is VuDroid, which supports both PDF and DjVu formats. http://code.google.com/p/vudroid/ I suggest it, not because I use it but because, at least in the Open Library version of the book's record, http://openlibrary.org/books/OL7169556M/ DjVu is listed as a streaming format. If I had an Android, I would give it a try. For iOS, there's DjVu reader that seems pretty decent. http://xzonesoftware.com/products/xdjvu I may check it out later tonight. Tom
Re: [CODE4LIB] opening a pdf file [diva]
I just installed EBookDroid (AFAICT the latest and greatest version of VuDroid) from the Android Market and tried it on the color version of Eric's canary file. It immediately loads numbered blank pages, then starts rendering the current page, which takes about 20 seconds. Previously rendered pages disappear pretty quickly after scrolling off of them. I works pretty snappily on other files and looks like it could turn out to be my PDF reader of choice.
