Quick Overview

Python wrapper around Linux CLI “convert” which works as an entrypoint around the Linux image processing ‘ImageMagick’.

Overview

pyimgconvert is a Python utility which acts as a wrapper around the magick convert Linux CLI program that is useful for convert input images to the desired format and saves them in an output directory specified by the user.

This utility requires you to pass an inputDir, inputFile, outputDir, outputFile, and all the other optional CLI arguments that the convert accepts as a string to the args argument of pyimgconvert.

Assumptions

This document assumes UNIX conventions and a bash shell. The script should work fine under Windows, but we have not actively tested on that platform – our dev envs are Linux Ubuntu and macOS.

pip3 install pyimgconvert

How to Use

mgz2imgslices needs at a minimum the following required command line arguments:

• -I | --inputDir <inputDir>: The input directory which contains the input image that is to be converted

• -i | --inputFile <inputFile>: The input image file to convert.

• -O| --outputDir <outputDir>: The output directory which will store the output image

• -o | --outputFile <outputFile>: The output file name (with extension) to save the output image

• Optional: -a | --args "ARGS: <otherArgs>": Pass all the other arguments that convert accepts to this argument using the double quotes.

Examples

First, let’s create a directory, say devel wherever you feel like it. We will place some test data in this directory to process with this plugin.

cd ~/
mkdir devel
cd devel
export DEVEL=$(pwd)

• Make sure your current working directory is devel. At this juncture it should contain the image file that you want to convert.

• Create an output directory named results in devel.

mkdir results && chmod 777 results

Example-1

pyimgconvert
    --inputDir ${DEVEL}/                \
    --inputFile image.jpg               \
    --outputDir ${DEVEL}/results/       \
    --outputFile image.png              \

Example-2

pyimgconvert
    --inputDir ${DEVEL}/                            \
    --inputFile image.jpg                           \
    --outputDir ${DEVEL}/results/                   \
    --outputFile image.png                          \
    --args "ARGS: -colorspace RGB    -resize 40% "

• The output image will be stored in the results directory.
