Getting extra Paragraphs

MacEvansCB · 12-19-2010, 11:18 AM

This one is going to be harder that the last one I found my own answer to.

When converting from PDF to RTF:
Every time a sentence starts at the beginning of a line within a paragraph, Calibre always starts a new paragraph.

Any way to keep this from happening???

I have also noticed that if a line ends in a capital letter, a new paragraph is started, even though there is no punctuation.

also found a case where a line starting with a double quote " also started a new paragraph, again with no other punctionation

And, hopefully finally, I've found a case where a typed-out ellipsis " . . . " at the end of a line starts a new paragraph.

There is no concept of a 'paragraph' in pdfs.

PDF unwrap works based off of punctuation, html that pdftohtml generates doesn't provide any other clues as to what is and is not a paragraph. You just need to fix it up yourself after conversion unfortunately.

There is a new pdf engine that will probably get released someday which contains info such as indentation and spacing between lines, which could be used to determine paragraph boundaries. No telling when it will be ready though.

Thanks.
I do know that this is a difficult area in PDF translation.
But even so, Calibre is light-years ahead of the translators inside of Acrobat Pro. Acrobat Pro makes a total mess of a document's paragraph structure, even when its clean.
I was hoping that I wouldn't have to scrub thru the Calibre conversions, but ... oh, well.
At least there's a lot less to look for.
