I just saw on your webpage that you're using LZW for bi-color images, you might want to take a look at JBIG2 (google for jbig2enc), it's a PDF-compatible compression algorithm that is vastly more efficient.

spomwii just notified me that the installation via "pip install spreads" currently installs 0.4.1, not 0.4.2.
To work around that, please download the tarball from here: https://pypi.python.org/pypi/spreads

Install it via "pip install spreads-v0.4.2.tar.gz" and you should be good!

I just released 0.4.2 to PyPi, so just run 'pip install --upgrade spreads' to get the latest version. What has changed: Fix for packaging issues Small bugfix for older Tesseract versions, where the "--list-langs" option is not available Small bugfix for terminals that don't support all UTF...

Hm, okay, that is weird! If you can select text your PDF reader, you have a hidden text layer, which calibre should be able to detect and extract.... But if you're using spreads, you can go a far easier route: Check your output folder, if you used the tesseract plugin, there should be a html-file th...

I think if your PDF does not have a text layer, Calibre will create a mobi with just the page images, which gives you exactly zero benefits, except bloated file size ;) So your first step should be to run OCR on your PDF, either using Acrobat itself (if you have the full version) or something like T...

@spomwii: That's a known problem, I unfortunately messed up the packaging for 0.4.1. Once I get back from 30c3, I will prepare a 0.4.2 that should resolve these issues. @mera451: My plan for windows-compatibility would actually be to ship a fully bundled version of the Python runtime, the required l...

'apt-get install exiftool'

A stupid mistake of mine... The distribution package was missing some modules...
I already had them installed on my machine, that's why I didn't catch it. I just pushed 0.4.1 to GitHub and PyPi, please run 'pip install -U spreads' and try again.
Sorry!

If you've installed via pip, it should be enough to run "pip install -U spreads". Be aware of the changed external dependencies, though (chdkptp)
