Based on: 10 PRINT "BOOK COVER" for Processing
Python-based book cover-generating algorithm inspired by 10PRINT. Artwork uses the symbols found on the Commodore PET keyboard:
Runs on Python 2 and 3.
Requires Python bindings for Cairo installed. While pycairo should work but is outdated, this implementation currently uses cairocffi.
There are two ways of generating book covers with this tool: one, generate a single book cover image by passing information directly through the command line arguments; or two, by passing a JSON file with information and generate a batch of book cover images.
Note that the default dimension of the image is set to 600×900 pixels.
tenprintcover.py --help
This prints all command line parameters.
tenprintcover.py --author "Clive Barker" --title "Imagica" --cover barker-imagica.png
Generate a single PNG book cover file barker-imagica.png for the book titled Imagica by the novelist Clive Barker.
tenprintcover.py --json-covers my-covers.json
This generates a book cover image for each line in the JSON file, where a single line has the following format (where subtitle may be set to null):
{"authors": "...", "identifier": "...", "subtitle": "...", "title": "...", "identifier_type": "...", "filename": "..."}
