If you have access to Adobe Acrobat (Pro) or similar software, then you have the possibility to process your image-based PDFs with an OCR text recognition in order to retrieve a text layer that is both searchable and "highlightable".
Note that I would advise you to select the option "Searchable image" for the PDF output style. The option "Formated text & graphics" usually alters too much the layout.

Again, if you have access to Adobe Acrobat or similar, then you should be able to optimize the size of your PDFs. You can even make scanned documents look better.
I got a 50 Mo PDF from one of 500 Mo... Without much loss of quality... but that was a time- & ressource-intensive task for my computer.

Hope this helps.

yes I know how to do this but the point is to convert searchable pdf to such that is not just to keep its appearance because if there are some more complicated diagrams the reader may not be able to display everything....

This Entourage Edge seems interesting but I just don't need the lcd screen...

Yes i have used (and been using) duokan. It also lets you open additional formats like epub, chm. Refer to kindle subforum for more info.

I'm not sure to understand what you mean. Do you want to use reflow?

m1rtinski · 07-28-2011, 02:56 PM

sorry, I was in hurry and know when I read my post I also don't understand it haha. I meant that if the e-reader can't display very well PDFs that contain diagrams etc, I can just make the pdf non-searchable (like a picture) so this problem won't exist anymore but the problem with this approach will be the size of the pdfs(and also that making annotations/highlightings will be impossible but anyway if the device doesn't support such feature who cares..) ...My concerns are that 532mhz may not be enough to deal with such PDFs...Compression of the image also won't work very well because it won't be clear enough to read..

I believe you are looking to solve the problem the wrong way (if problem there is).

I think most e-ereaders can deal with searchable PDF quite well, even with diagram, if you do not try to reflow them.
As I mentioned, you can have PDF that are image-based and that are searchable (+ highlightable) if you check the right option for making the OCR.

However, if someone who already owns an e-reader could confirm my first assertion, it would be safer.

It is how Thierry says. He's right.

On the other hand, I have a Kindle DXG and I'm glad. I use Doukan to handle PDFs: it allows zoom of all kind, crop margins, highlights, make notes, use dictionary, read multiples columns. It't not perfect (some problem with reflow), but it is really helpful.

There's an e-ink tablet out from Asus right now. I'm not sure how easy it is to come by and the software ain't finished. It's supposed to do web, word processing, games, apps...but none of that is really up to scratch yet.
But it should read PDFs very nicely.
I think it's between 9 and 11 inches (maybe 9). That's nine inches of E-INK.
It's literally like reading a sheet of paper in your hand.

m1rtinski · 07-29-2011, 05:21 AM

Between Kindle DXG and PocketBook Pro 902 which one do you think is a better choice ? PB 902 is a bit more expensive but has 256 ram...And the Kindle with duokan probably will be better at dealing with PDFs :?

Does Doukan also allows to increase the contrast of the fonts in the pdf file like the original Kindle software does?
I like this feature of the Kindle very much and how easy they made this feature to make the fonts darker by few press of a button.

Yes, it allows to increase the contrast in 5 levels, better than the original Kindle software, just pressing the Aa button y selecting the one you want.

I think I will buy PocketBook 903...It is more expensive than Kindle DXG but has 256 ram good pdf support and touchscreen (also wifi bluetooth and 3g) so I think it is worth buying

reprep · 07-29-2011, 01:54 PM

well pearl vs vizplex e-ink really matter more than 128 mb vs 256 mb ram. Google for videos and see the difference.

You are right about wifi. I really would like to have my kindle DXG to have wifi along with 3g. I don't like touchscreen so it is not a dealbreaker for me.

And the deference between screens Vizplex and Pearl is more noticeable when the mainly format used is PFD, wich generally need more contrast than other format, like .mobi or .epub, to look readable. I a think (not sure) that the 903 doesn't allow to increase the contrast.

m1rtinski · 07-29-2011, 02:52 PM

hmmm...I saw several videos but the difference is not really big actually :? well, the pearl display is noticeably better but I still think that 256 ram instead of 128, touch screen and better pdf support are more important advantages than slightly better screen. I just need to see what I read...the resolution is the same so...I am not going to watch pictures on the device, just need the diagrams to be fine and readable
