imgdiff 1.3.0

Present two images side-by-side for visual comparison

imgdiff

A command-line tool that combines two pictures into a single, larger one, and opens a GUI window (provided by the Python Imaging Library) or an external image viewer.

You could use it with a version control tool, e.g.

bzr diff *.png --using=imgdiff

Installation

pip install imgdiff or download it from PyPI.

Command-Line Help

Usage: imgdiff image1 image2

Compare two images side-by-side

Options:
  -h, --help          show this help message and exit
  -o OUTFILE          write the combined image to a file instead of showing it
  --viewer=VIEWER     use an external program to view an image instead using
                      the builtin viewer
  --grace=GRACE       seconds to wait before removing temporary file when
                      using an external viewer, in case it forks into
                      background
  --auto              pick orientation automatically (default)
  --lr, --left-right  force orientation to left-and-right
  --tb, --top-bottom  force orientation to top-and-bottom

Output Example

Here the images are wide and short, so imgdiff decided to put them one above the other.
