Re: pdfbeads on Ubuntu 18.10

The standard ImageMagick version in Ubuntu’s repositories doesn’t support jpeg2000 compression. You need to compile newer version of ImageMagick to have this (it may be tricky as there are other dependencies that need to be resolved first). Moreover there is no jbig2 compression available by defaul...

Re: Spreads for single camera

I haven't made any plugin progress on this but I've posted a standalone script I've been using in my workflow at the moment here, in case it's of any use to anyone else: https://gist.github.com/gareth8118/c792fe58ed4065821968 #!/usr/bin/env python import shutil import argparse def interleave_pages(s...

Re: Spreads for single camera

That sounds right. One thing to watch out for is that Spreads may have been inserting EXIF metadata into all of the shots to tag them as 'rotated'. So if your rotation seems wonky, I'd check that possibility first. Oh, that's interesting - I had noticed that the autorotate plugin used the EXIF to r...

Spreads for single camera

I'm working away at getting spreads useable for the cardboard-box scanner use case since I'm still negotiating space for a two-camera setup. Spreads is happy enough capturing in single camera mode now so I have some data to work with as I try to hone the workflow. The way I've shot the first book is...

Re: Spreads development environment

On Ubuntu, you will have to install "turbojpeg-devel". See this GitHub issue for a longer discussion of the relocation error: https://github.com/jbaiter/jpegtran-cffi/issues/5 For the sake of completeness: I couldn't find turbojpeg-devel in the repos, but I could find libturbojpeg which y...

Re: Spreads development environment

Can't seem to edit the post so I'll just reply to my own post - the corresponding Debian failure looks like this

Code: Select all

local/lib/python2.7/site-packages/jpegtran/__pycache__/_cffi__xb366312fxf3ca0677.c:186:27: fatal error: turbojpeg.h: No such file or directory

Spreads development environment

Hi there, I'm starting to set up a development environment based on some IRC conversations with jbaiter. I've documented what is working so far on this branch here: https://github.com/gareth8118/spreads/blob/doc-updates/doc/developers.rst and I'll open a pull request when it's useable. However, I'm ...

My day job is in the semiconductor industry, and by night I like to tinker with a...
