HTML → EPUB: Either "Out of memory" or "openBinaryFile: invalid argument (Invalid argument)"

[-- Attachment #1.1: Type: text/plain, Size: 1131 bytes --]



Hello


On Windows (7, 32 bits), I'm trying to convert a ~450 page PDF into EPUB.


1. I used "mutool draw" to convert the PDF into a single, ~10MB HTML:


pandoc -f html -t epub3 -o output.epub input.html

(~10mn wait on my sluggish computer)

"Out of memory":


2. Next, I reran "mutool draw" to convert the PDF as one page = one HTML 
page:


pandoc -o output.epub  *.html

pandoc: *.html: openBinaryFile: invalid argument (Invalid argument) 


3.Finally, I used pandoc to concatenate all the HTML files, but still got a 
"openBinaryFile: invalid argument (Invalid argument)".


pandoc *.html > full.html

pandoc: *.html: openBinaryFile: invalid argument (Invalid argument)


What do you suggest I try?


Thank you.

That's extremely strange.  Your shell should be expanding the *
in *.html before it even gets to pandoc.  So if pandoc can see
the *, your shell hasn't done what it's supposed to.

What OS are you using, and what version of pandoc?

It's Windows (7, 32 bits) and pandoc 2.9.2.1.

Per this thread…
https://groups.google.com/d/msg/pandoc-discuss/eMfCGU3Gn8E/bEhyLpUYBAAJ
… I named the batch file pandoc.cmd, and re-ran the command thusly:

echo output.epub | pandoc *.html -

It runs for a few minutes, and ends with displaying some HTML… but no .epub 
can be found.

I assume I'm not using the command correctly. Can pandoc use the standard 
input?

Re: HTML → EPUB: Either "Out of memory" or "openBinaryFile: invalid argument (Invalid argument)"

[John MacFarlane]

Yes, pandoc can use stdin (see the manual), but only when
files aren't explicitly specified on the command line.  You
can't use stdin AND name input files, as in your batch file.

I have no idea why you wouldn't be getting shell expansion
of *.html; maybe someone who uses Windows could comment.
Are there perhaps special characters or spaces in your
.html file names?  Try

pandoc "*.html"

Windows doesn't support shell expansion!
You need to create a batch file or run in PowerShell ...

HTML → EPUB: Either "Out of memory" or "openBinaryFile: invalid argument (Invalid argument)"

[Kolen Cheung]

[-- Attachment #1: Type: text/plain, Size: 1297 bytes --]

A side note, since your goal is to convert from PDF to ePub, you probably will have better results using other tools. Eg I know it can be converted to docx, and then from docx to ePub. There may he tool that can help you convert that directly too. Essentially for the tools you choose, you’d want to choose one preserving most information. And since pandoc focuses many on the structure of the document, much other information would be lost. The choice of tool also depends on which ones you’re comfortable with, Eg the PDF to docx I mentioned probably can be done by Adobe Acrobat and MS Word. But they are proprietary and difficult to run from the command line.

In your case, since you have a tool preconverted them to html already, html to ePub can be done better by some other engines (since the 2 are closely related.) may be you can try Calibre which also have a cli.

Since I had a Linux host available, I went around that issue with Windows 
and shell expansion.

pandoc -f html -t epub3 -o output.epub input.html


pandoc ran successfully (no error message), but the EPUB can't be opened in 
a Windows GUI application that supports EPUB files ("Error loading 
file.epub"). Likewise, I can't open the file after changing its extension 
from EPUB to ZIP.

Here's the input files (HTML + PNGs):

Do I need extra options in the command line?

What pandoc version are you running on the linux box?
This works fine for me.

Re: HTML → EPUB: Either "Out of memory" or "openBinaryFile: invalid argument (Invalid argument)"

pandoc 2.5.2 on Ubuntu 19.10.

Turns out I had to use "-t epub" instead of "-t epub3" :

pandoc -f html -t epub -o output.epub input.html

Thank you.

Re: HTML → EPUB: Either "Out of memory" or "openBinaryFile: invalid argument (Invalid argument)"

[Kolen Cheung]

[-- Attachment #1.1: Type: text/plain, Size: 3992 bytes --]

Version too old. Try to reproduce it using the latest 
version: https://github.com/jgm/pandoc/releases/latest There's various way 
to install it, e.g. you can just unzip pandoc-2.9.2.1-linux-amd64.tar.gz 
and put pandoc and pandoc-citeproc to somewhere in your path, such as 
~/.local/bin

(To take one more step you can go to the GitHub Action to download the 
latest nightly build to make sure the problem has not been solved yet.)

In general you'd want to ensure the problem has not been solved yet, and to 
do that you want the latest version, which unfortunately in distros with 
package manager can be a big problem because people often just use the one 
from there, which is too old especially from Ubuntu.

Re: HTML → EPUB: Either "Out of memory" or "openBinaryFile: invalid argument (Invalid argument)"

[Heck Lennon]

[-- Attachment #1.1: Type: text/plain, Size: 4644 bytes --]

Thanks for the tip.

1. Removed the Ubuntu 2.5-2 package through apt-get remove
2. Downloaded and installed pandoc-2.9.2.1-1-amd64.deb
3. Ran : pandoc -f html -t epub3 -o output.epub3.epub input.html AND pandoc 
-f html -t epub -o output.epub2.epub input.html
4. Opened each file in Windows with SumatraPDF (which suppports epub): Both 
opened OK.

The issue remains on how to better convert PDF to HTML, but this has 
nothing to do with pandoc.

Thank you all !

I think you could still ask people here. Pandoc Discuss is more casual and 
as long as you make it clear I think people are ok with it. There's some 
experts here about format conversions (for obvious reasons.)

Or if you still want to use pandoc in part of the "from PDF" workflow then 
it is very relevant here. Essentially pandoc can take many formats as input 
and many other softwares can read from PDF and write to a certain formats 
pandoc understands. The question then which intermediate format and 
software are best to use.

e.g. I have tried Acrobat/Word to docx and then pass it to pandoc.

For PDF images I converted them to svg and inline as an image by pdf2svg 
(inline PDF as image is also ok for some output formats.)
