Please test these files on Paperwhite
I'm planning to buy a Kindle Paperwhite. Then asked someone to test my PDFs on his kindle and this is the answer :
"cannot select the text. whole page gets selected as its a image. beleive me its a pain to read this pdf on e-ink screen." Wow ! Can anyone else test attached files on paperwhite ? These files are optimized using K2PDF Opt. Is navigation fast ? Is texts selectable ? Thanks Last edited by rostamiani; 11-29-2012 at 08:39 PM. |

No need for a Paperwhite. It has problems even on a computer, with Adobe Reader. The text on pages 3, 9, 12, 19, 22 (and maybe more) of the first attachement isn't selectable. It's like the program forgot to OCR it or something. Judging by the misalignment of some of the text, and the low quality (not scaling upon zooming), I'd say that these documents are just images with positional OCR behind them. It even OCR'ed the first figure on page 10.
I probably wouldn't put these on a reading device... The text looks very jagged and I can see why he/she would think it's painful to read. Opening it in Adobe Reader and going to File -> Properties, it says that the document is 3.37 x 4.43 inches, which InDesign translated as 242.64 x 318.96 pixels! That's very, very low on a Paperwhite (758×1024, according to Wikipedia), or even the rest of the Kindles (600x800). |

I Created this PDFs with K2PDF Opt to optimize it for Kindle: https://www.mobileread.com/forums/sho...d.php?t=144711 The original file is here : http://www.autodeskresearch.com/pdf/eg01.pdf I know that the resolution is low because I created it for my Nook Simple Touch 1 . With Nook I cannot select text .even on selectable pages ! Can Paperwhite handle this ? 2 . And I don't know if navigation speed is enough on Paperwhite |

The "Nook Simple Touch" also has a resolution of 600x800, so it probably doesn't look very good on it either.
Source looks very good except that, well, you're trying to convert a PDF to a PDF... And that's very bad. PDF is meant as a final destination. For a proper conversion, you would need the original Word/OpenOffice/LibreOffice document (or whatever the author used), but then again, the equations aren't helping either - they will need to be converted to GIF/PNG, because Kindles don't do SVG. The rest of the images should be kept as colour images, in case someone reads it on a Kindle Fire, not automatically converted to 1 bit images (black). Heh. If you were hoping for a one click conversion solution, there is none. Personally, I would extract the text with ABBYY FineReader, proofread it, save as RTF, run a custom Word macro that gets rid of the styles (but keeps italics, bolds, superscripts, places the footnotes as inline text, etc), import into InDesign, redo the layout, save it as an ePub, convert the ePub to Mobi, then proofread the final product and adjust as necessary if something doesn't look right.

I've done OCR again in Acrobat and then I was able to select single words. Speed was normal. Last edited by markom; 11-30-2012 at 03:14 PM. |

The paperwhite looks pretty fast at handling PDFs--starting to approach tablet capability, with "pinch to zoom" feature. Check out this excellent "triparison" video review at about the 13-minute mark, where the author shows how three "glow" e-readers compare at reading PDF files (paperwhite on the left). |
