For an optimal reading experience, we strongly recommend you choose EPUB whenever possible.Īnd for all the Kindle users who cannot read EPUB on their devices, I will also not recommend PDF. You can replace the soft scene breaks with your own text or graphic to further customize the look and feel of your ebooks.We recommend that you avoid the pdf format whenever possible, unless your document has been specifically formatted for your Cybook and your personal preferences (texte size, choice of font…) since the inherent rigidity of this format will never allow a completely personnalised display.ĮPUB is the ideal format for ebooks. In this example, I had to reduce the line unwrap factor to 0.5 to get the paragraphs to be readable.Ī soft scene break is when there is an extra space between different scenes in a book rather than the use of a wingding (?) or some small graphic such as hashmarks (#) or bullets ( You often will have to play around with this and reformat at different settings. 40 and frankly that setting usually never works for me. So check the box and the options will become available. The default for Heuristic Processing is that it is disabled. In this example, you can see the paragraph is broken up by these weird line wraps and reading a book in this format would I use this function primarily to unwrap lines. Highlight the text to be removed and then replace the numbers with \d . You could add a \s between “Lacey” or “Calhoun” and the just to be on the safe side: Liberating Lacey\s*Ĭalibre has a feature called Heuristic Processing which scans the ebook and tries to search for common errors and fixes them. Remember, the number and text will often change from page to page.īasically I copy any text that needs to be removed and then replace the number with \d .

If that’s all you need to exclude, then press “OK” and the conversion will begin. Your search expression appears in the left with the replacement text (blank in this case) on the left. Press “Add” or your conversion won’t include the search and replace you just constructed. Press okay and you’ll be sent back to the Search and Replace window. The replace term is left completely blank. Now when you scroll down, those pesky stray line numbers should be highlighted. I’m sure there is a more sophisticated query but it works for me. The | is called a pipe and it is used to separate sets of regular expressions. Or, if you’re really savvy, you’ll use the \w code. To construct the search text, you would simply add the S or N before or after the number. Or sometimes the line numbers will end with S and N. The yellow highlighted text will be removed:Īs you scroll down, sometimes you will see these line numbers that start with S or N. You can click “Test” to determine whether your expression is going to strip out the right text. The “ ” is a greedy qualifier which means it will remove as many digits as possible.

Some PDFs have line numbers that are on a hidden layer. I’m going to address three of the most common problems when converting a PDF to ePub and what you can do to address those problems. There are some tips and tricks in Calibre’s PDF conversion engine that can be used to produce very clean and readable PDFs. Often there will be stray letters or numbers or headers that affect the output of an ebook.
