========== Deba bōchō ========== Slice up PDFs like a pro:: % bocho my-fancy-file.pdf --pages 1 3 5 6 10 --angle 30 --zoom 1.6 my-fancy-file-bocho-630x290.png Takes a PDF file and creates a "stacked page" preview from a selection of pages. It accepts a bunch of options for customising the output (pass the ``-h`` flag for details). Installation ============ Requires ImageMagick so you might need to, e.g:: % sudo apt-get install imagemagick If you want to use ``Wand`` instead of calling ``convert`` directly, you'll also need to perform some some additional steps, e.g:: % sudo apt-get install libmagickwand-dev % pip install wand See their installation instructions for more details. On OS X, you'll want to use Homebrew to get the low-level dependencies in place:: % brew install ghostscript imagemagick Once all that's sorted, you just need to ``pip install deba-bocho``. PyPy: Oh My! ============ For simple operations, there's not much difference in performance between CPython and PyPy. If you want to use the ``shadow`` effect, it's a different matter. Cue unscientific benchmarking run on my laptop... Python 2.7:: % time bocho /tmp/report.pdf --preset example --shadow ... bocho /tmp/report.pdf --preset example --shadow 35.89s user 0.15s system 99% cpu 36.132 total PyPy:: % time bocho /tmp/report.pdf --preset example --shadow ... bocho /tmp/report.pdf --preset example --shadow 4.10s user 0.18s system 99% cpu 4.297 total Making PyPy about 10x as fast as Python 2.7. The same process without ``--shadow`` takes around 2.5 seconds with both implementations. Usage ===== For information on usage, run ``bocho --help``. If you want to use it as a module:: >>> import bocho >>> help(bocho.assemble) Configuration ============= If you will be using the same options many times, it's probably worth creating a preset in a ``config.ini`` file (see config.example.ini_ or the example below to get started). .. _config.example.ini: https://github.com/jimr/deba-bocho/blob/master/config.example.ini By default, ``bocho`` will check for ``$HOME/.config/bocho/config.ini``, so it's probably best to keep your config there, but you can pass the ``--config`` option with the path to an alternative location. .. code-block:: ini [example] pages = 1,3,5,7,9 width = 630 height = 290 border = 4 reuse = true delete = true verbose = true use_convert = true parallel = 5 You can tell ``bocho`` to use this preset by calling:: bocho /path/to/file.pdf --preset example [--config /path/to/config.ini] TODO ==== - implement rotation properly ✓ - allow a "zoom" option ✓ - optional drop-shadows ✓ - make shadows smarter in their orientation (they're currently uniform, not respecting the angle / transformations) - make the basic edge separators optional ✓ - automatic spacing as an option as well as fixed pixel spacing - horizontal and vertical spacing ✓ - horizontal and vertical offsets ✓ - optional right-to-left stacking ✓ - handle non-A4 aspect ratio input documents ✓ - optionally apply transforms: - affine ✗ (abandoned in favour of vertical / horizontal shear effects) - shear ✓ (applied by creating simplified affine transforms) - stretch (can be achieved in a similar fashion to shear) - perspective - ensure sliced PNGs are large enough when custom width / height are specified - fix x and y spacing calculation to account for any applied rotation & transformation - allow transforms to be configurable (probably with presets defined in an ``.ini`` file) - drop the PyPDF dependency ✓ - use an ImageMagick binding rather than using ``subprocess`` to call ``convert`` ✓ (Wand) - optionally re-use pages between runs ✓ - allow user-specified resolution for the PDF to PNG conversion ✓ - docs ✓ - pretty pictures illustrating the effect of the various options - use proper logging License ======= See ``LICENSE.txt``. Test images are from the USC-SIPI Image Database (http://sipi.usc.edu/database/). The test PDF is "Distributed Space-Time Interference Alignment" (`arXiv:1405.0032 <http://arxiv.org/abs/1405.0032>`_).
