# TeX to epub conversion

I want to create epub document, but I only have a tex file (unfortunately, mathematical formulas, and drawing diagrams). I tried pandoc: tex to html, tex to xhtml, to xml, but nothing works properly. I use tikz.

You can do the epub file with png or svg?

Some ideas?

• This question has been asked before several times. Look at the answers here: tex.stackexchange.com/questions/1551/use-latex-to-produce-epub. From my personal experience, every solution needs some tweaking. I've been playing with tex4ht to generate html, do some tweaking, build the epub with a script, some more tweaking and then calibre. As for images, I don't remember if epub supports svg, but it does support png. – Nico Jan 30 '14 at 14:25
• Thx, I'll try, but I must have an automatic tool. – mkjasinski Jan 30 '14 at 14:29
• The tweaking I've mentioned I've managed to do it with a script. Actually, 2. One to convert to html and one to create the epub. – Nico Jan 30 '14 at 14:34
• I've done a lot, but I can't do charts. – mkjasinski Jan 30 '14 at 14:37
• You're unlikely to get perfect results with pandoc, unless your tex file is pretty simple. However, this might be of interest: a pandoc filter that will process the tikz diagrams in your document and turn them into embedded images which can appear in the EPUB.

OK, I have solution.

1. create pdf (input.tex)

pdflatex input.tex

2. create png

convert -quality 05 input.pdf output.png

3. create html (png files have so much how many pages in PDF file, for example: 4)

<!DOCTYPE html>
<html>
<meta charset="UTF-8"/>
<style>
img {
display: block;
}
</style>
<body>
<img src="output-0.png"/>
<img src="output-1.png"/>
<img src="output-2.png"/>
<img src="output-3.png"/>
</body>
</html>

4. create metadata for EPUB (metadata.xml)

<dc:title>[ebook_name]</dc:title>
<dc:identifier id="pub-id">[ebook_id]</dc:identifier>
<dc:creator opf:file-as="[secondName,firstName]" opf:role="aut">[firstName secondName]</dc:creator>
<dc:rights>[company]</dc:rights>
<dc:language>[lang]</dc:language>
<dc:publisher>[company]</dc:publisher>

5. create epub file

pandoc -f html -t epub3 --epub-metadata=metadata.xml -o output.epub output.html


Your best bet might be the tex -> pdf -> epub route. Calibre or other software can make a decent attempt, but it will probably not be fully automatic.

• I tried, but unfortunately there are problems with graphs. I must have an automatic conversion tool, Tex is built automatically, epub also must be built automatically. – mkjasinski Jan 30 '14 at 14:28
• Using pdf as an intermediate format is a disaster. Loses all semantic markup, many paragraphs, introduces new paragraphs at every page break. Just. Don't. – WillAdams Jan 30 '14 at 14:43
