Huge PDFs and scanned books

[janosch]

I would like to pose two questions concerning the capabilities of the iLiad:

Is the iLiad capable to display really large PDF files? For example the file

http://modular.fas.harvard.edu/sga/sga5/SGA5.pdf

is about 60 MB. Can the iLiad process and display this file?

Secondly, the PDF file

http://archive.numdam.org/article/PM...60__4__5_0.pdf

("only" about 27 MB) consists, as the above, of scanned text (but smaller font size as above) which is not resizeable manually. I tried to figure out which zoom capabilities are offered by the iLiad reading earlier posts but I couldn't find an answer to my question. It seems to be necessary to resize/reformat files "offline" before loading them on the iLiad if the font size is too small. My question is of there is some sort of zoom feature (also for graphics)?

Could anyone with an iLiad try to get an eye on the above files and tell me if the files are reasonably readable on an iLiad?

This would be interesting also because the above books are out of print. :-)

Thanks a lot!

This file seemed to work just fine on my iLiad.

This one works too, but the pages load slow since it has to render the graphics for each page. And, yes, the text is small. It's readable, but nothing that I'd spend lots of time looking at.

Not yet. Next revision (due out at the end of this month) is supposed to do zoom. This book may actually work well with the zoom since it has such large margins.

Thank you a lot rlauzon.

I downloaded SGA5.pdf, a scanned copy of some math notes, and confirmed that it
displayed on the Iliad without difficulty. The pages are 8.5 x 11 inches, scanned
at 251 bpi with the maximum size of the type block about 6.5 x 9 inches. This
would make it possible to show the text at nearly orginal size by cropping the
white space, rotating to landscape, and showing 1/2 a page at a time.

As to file sizes:- I loaded a scanned copy of Hoyt's Practical Quotations
to my Iliad - on a CF. The book was scanned at 600 bpi, 1376 pages 6 x 9.6 inches,
producing a file of 212 MB. It took about 40 seconds to load but once loaded
consecutive pages turned in a second or so. The type was barely readable at
a distance of 2 inches but beautifully sharp and clear when viewed with a magnifying
glass. The math notes on SGA5.pdf were also sharp and clear when looked at with
a magnifying glass.

I've finished tweaking some out of copyright scanned books to reduce file size and
remove white space and hope to post something about them soon.
