pictureshow 0.2.3

Save pictures to PDF

Save pictures to PDF — from the command line, or from your Python programs.

As a command line tool

Usage:

usage: pictureshow [-h] [-v] [-q] [-m MARGIN] [-s] PIC [PIC ...] PDF

positional arguments:
  PIC                   one or more input picture file paths
  PDF                   output PDF file path

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit
  -q, --quiet           suppress printing to stdout
  -m MARGIN, --margin MARGIN
                        width of empty margin on page; default 72 points (1
                        inch)
  -s, --stretch-small   scale small pictures up to fit drawing area

Simple example — saving a single picture to PDF:

$ pictureshow picture.png pic.pdf
Saved 1 picture to '/.../pic.pdf'

Using a glob pattern, in the quiet mode:

$ pictureshow -q *.jpg jpg_pics.pdf

Using multiple glob patterns, with margin width specified:

$ pictureshow -m 36 *.png *.jpg *.gif all_pics.pdf
Saved 32 pictures to '/.../all_pics.pdf'

Combining glob pattern and additional filenames, with zero margin, stretching small pictures to page:

$ pictureshow chart.gif *.jpg graph.png pics.pdf -m 0 -s
Saved 7 pictures to '/.../pics.pdf'

As a Python library

Using the PictureShow class:

from pictureshow import PictureShow

pic_show = PictureShow('pic1.png', 'pic2.jpg', 'pic3.gif')
pic_show.save_pdf('pictures.pdf')

Using the pictures_to_pdf shortcut function:

from pictureshow import pictures_to_pdf

pictures_to_pdf('pic1.png', 'pic2.jpg', 'pic3.gif', 'pictures.pdf')

It is however recommended to pass the output file name as a keyword argument:

from pictureshow import pictures_to_pdf

list_of_pictures = ['pic1.png', 'pic2.jpg', 'pic3.gif']
pictures_to_pdf(*list_of_pictures, pdf_file='pictures.pdf')

Using a glob pattern, sorted by name, with a two-inch margin, stretching smaller pictures to area:

from pathlib import Path

from pictureshow import pictures_to_pdf

list_of_pictures = sorted(Path.cwd().glob('screenshots/*.png'))
pictures_to_pdf(
    *list_of_pictures,
    pdf_file='screenshots.pdf',
    margin=144,
    stretch_small=True
)
