Description lbartolome 2018-11-15 19:34:19 UTC
Description:
I use Writer to create both pdfs for imprints and epubs. My current LO is 5.3.7 and I'm testing 6.2.0.0.alpha1 (x64). 
Since there's no option to export to pdf with trim marks and color bars, I created a pdf with them on another program from a page with a logo on it. I covered the logo with a white square before saving this and importing as bit map on page style.
LO 5 correctly imported it without the logo showing, but it wasn't so with LO 6.2, which also made the lines fuzzy.

Regarding the epub export, I am using Writer2Latex 1.6 extension (writer2html) in LO 5 and the LO6 default epub export filter. 

Neither of them created a cover for the book even though I selected an image in the LO 6.2 filter menu. 

LO 6.2 epub export filter only allows to select either new file at header or page break when it should be able to let you chose whether one or both and at which header level even if it's not adding additional options as W2L does.

LO 6.2 epub filter didn't export chapter numbers, which W2L handled correctly.

LO 6.2 epub filter added and F in front of the footnote number and added a line between notes, which make it look pretty weird on ADE. 

And LO 6.2 is not exporting style formating correctly, creating a lot of garbage code in the epub instead of a clean export. 
I'm copying the output from LO 6.2 epub export filter

Compare the same lines from W2L export
    <h1 id="toc0"><span class="SectionNumber">CAPÍTULO I  </span>Roma. (41158 palabras)</h1>
    <p class="Standard" lang="fr-FR" xml:lang="fr-FR">&#160;</p>
    <p class="Standard">Nuestros lectores desearán —al menos esa es nuestra esperanza— posponer por unos instantes la explicación que va a tener lugar entre Pètrus y Regine, a fin de seguir en su peregrinación a uno de los héroes de esta historia, héroe abandonado durante mucho tiempo y en el que nos parece que querían interesarse. </p>

You can see that LO epub export filter is not exporting language information, which is used by epub readers to show the right dictionary for the words.


Actual Results:
Messy epub
Fuzzy lines in bitmap

Expected Results:
Output should have been at least as good as in previous LO for both things:
1. Handling of pdf imports as bitmaps keeping quality
2. epub filter should have been worked from the best existing filter around (Writer2Latex's writer2html) to add up to it.
3. If the software had done trim/crop marks and color bars, I shouldn't have needed another program to create the bitmap.


Reproducible: Always

Mark/Miklos: thought you might be interested in this one since it concerns epub part.

FWIW, the output from a document with text copied as plain text and then formatted is cleaner than the output from a working texts with deletions, additions and so on.

See example below:

<p class="para0"><span class="span4">Branadel había llegado hasta la ciudad

Exported with Writer2html (Writer2Latex)
    <h1 dir="ltr" id="toc1"><a id="RefHeadingToc3066392408007"></a>Alas de sangre</h1>

Please, note that class names in the second case have been inherited from parent document while they've been assigned by export filter, even for headers.

Hello Lbartolome.
A new major release of LibreOffice is available since this bug was reported.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.
Comment 5 lbartolome 2019-11-12 18:45:59 UTC
Import of pdf as bitmap in page style is now correct on version 6.3 and transparencies are not showing.

epub output is as messy as before and not keeping styles. Heading is exporting as <p> +span class instead of <h> and spans are not being closed when changing class or closing tag (h, p...) increasing file size up to 10%. Copying and pasting as text and restyling before exporting is a workaround to get rid of the extra spans, but not viable with texts with hundreds of notes additional to the regular italics and headings.
