Calibre PDF->EPUB - How to set up making gap only after dot?

[regis221]

Do you know how to set up in calibre making gaps (enters) only after dot?

I convert pdf to epub with "Heuristic Processing", but still I see unnecessary gaps on my ebook reader. Between two words is "enter", but there should be only "space".

There is maybe any css code to solve it?

That sounds like the lines did not join (not unusual). Adjust the 'Unwrap factor value don a small amount (not bigger than 5 points) and try converting again

BTW EPUB does not use 'Enter' to start a new line, it ends the current code block type (eg </p> ) and starts a new one. Code Line Gaps in between don't count and exist for human eyes.

Do read the Stickies at the top of this forum and the FAQ topics on conversion at the calibre Help page
PDF is not a great source

I use unwrap factor value about 0,15. It gives the best results, but sometimes I see gap on epub format after word which is the last words in pdf line (not last one in paragraph). That word is often word inside sentence and there should be only space (not a gap/"enter").

I would like to add css code for command <p class="calibre1"> </p> to make rule for calibre to use this command only if after word is dot.

If calibre use that command only after a dot, it will solve problem with breaking text in half of sentence.
But I have no idea how to write that code.

Using the editor, where I can see the code makes these easy (usually ) to create 'fixes'. IMHO trying to make this happen during a Conversion YMMV


I use a replace method to remove the 'empty paragraph' (0 or more whitespace)

Blah Blah.</p>
<p class="calibre1"> </p>

REGEX mode search:

\.</p>\s+<p class="calibre1">\s*</p>

Replace:

.</p>

Note I escape the period in the search because it is a wildcard

"No matches found"

Solution:
search:

([-,—,a,ą,b,c,ć,d,e,ę,f,g,h,i,j,k,l,ł,m,n,ń,o,ó,p,r,s,ś,t,u,w,y,z,ź,ż,0,1,2,3,4,5,6,7,8,9])</p>\s+<p class="calibre1">

replace:

\1

You do not nee all those commas.

The character set represented by [characters] matches all characters in the brackets (even if some are repeated ).
