Help with Calibre
Hi There.....
Looking for assistance/tips regarding e-book conversion:
- running Calibre 0.7.23 on MacBook Pro; device > iPad + iBooks
- attempted to convert a number of pdf's to epub format ( preferences set accordingly > input=pdf, output=epub; device=iPad
- while some pdf books/articles were converted right, others :

> lost images
> a 250 pages book became over 1000 pages
> table of content displayed one page per item
> footer/header scrambled with text
> forcing table of contents generates lots of pages, one line per page
> maths formulas converted to text, one character per line

To cut it short :

- how to tell which pdf can or cannot be converted to epub?
- what preferences setting to use for input=pdf, output=epub for iBooks , iPad, MacBook Pro running OS 10.5.8?

Many thanks

Welcome to MobileRead, Bocha.

If you don't get an answer soon, you might try posting your question in the Calibre forum..........

Welcome to mobileread ....

You may have discovered one of the reasons why PDFs are poor source files for ebooks - the conversion processes can't figure out what to do with the images in PDFs. The Calibre site states ....
Quote:
The PDF conversion tries to extract the text and images from the PDF file and convert them to an HTML based ebook. Some PDF files have images in a format that cannot be extracted (vector images). All tables are also represented as vector diagrams, thus they cannot be extracted.

There is no way to tell how well a pdf will convert, other than converting it

As for preferences, the only really important one is the line unwrapping factor under PDF Input

Hi Bocha,

I have a similar situation trying to make my own book files convertible to as many ereader formats as possible; also working on a MacBook Pro. You might find some of the posts on the thread I started helpful. https://www.mobileread.com/forums/sho...07#post1164807

I'm still sorting out the information myself. As I find out more I'll redirect you to the above or reply again here. Please let me know what you figure out, too. Good luck!
