Slice up PDFs like a pro.
Project description
Slice up PDFs like a pro:
% python bocho.py my-fancy-file.pdf --pages 1 3 5 6 10 --angle 30 --zoom 1.6 my-fancy-file-bocho-630x290.png
bocho 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 and the contents of requirements.txt, e.g:
% sudo apt-get install imagemagick % pip install -r requirements.txt
On OS X, it’s a bit more complicated:
% brew install ghostscript % brew install imagemagick % ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install --allow-external pyPdf --allow-unverified pyPdf -r requirements.txt
TODO
implement rotation properly ✓
allow a “zoom” option ✓
optional drop-shadows (and make the basic edge separators optional also)
automatic spacing as an option as well as fixed pixel spacing
horizontal and vertical spacing (currently only horizontal)
horizontal and vertical offsets ✓
optional right-to-left stacking ✓
handle non-A4 aspect ratio input documents ✓
optionally apply transforms:
affine ✓ (basic, subtle, non-configurable)
perspective
ensure sliced PNGs are large enough when custom width / height are specified
fix x and y spacing calculation to account for any applied transformations
if an angle is specified, apply the offsets after rotation, not before
allow transforms to be configurable (probably with presets defined in an .ini file)
