calibre - very slow conversion, very slow on PRS
I found some interesting PDF-ebooks. Because PDF viewing on my PRS-700 is not very comfortable I tried to convert them the following way:
- extract the text from the PDF via copy/paste to a Word2007 file.
- Do some corrections
- safe as ebook.rtf
import with calibre and convert to epub.
The conversion for one book (about 500 pages on the PRS700) needs more than 3 hours.
The size of the epub-book is 0.7 MB
The ebook on the PRS700 is very slow, sometimes I need 2 or 3 minutes to change a page.
Is thee any efficient way to do this kind of conversion?
Where can be the reason for the very long conversion time (usually conversion is done within 10-20 seconds)
perhaps the fonts ?
please help, because I still have mor than 50 books in PDF format to be converted...
