Easily Manipulate Images Using Python: Change Brightness, Contrast, Sharpness, Resize
Mass Manipulate Images Using Python: Change Brightness, Contrast, Sharpness, Resize, Compress, Crop and Convert (e.g png to jpg). A simple script (wrapper) using pillow. Licensed Under: GNU General Public License v3 or later (GPLv3+)
python >= 3.5, pillow
Simplest option is to install with pip using sudo.
sudo python3 -m pip install pillowcover --upgrade
--OR-- Install as a user without sudo. This installs it in ~/.local/bin/ make sure this path is in your $PATH.
python3 -m pip install --user pillowcover --upgrade
If not found, add the following to your .bashrc or .zshrc
# Add to PATH to Install and run programs with "pip install --user"
export PATH=$PATH:~/.local/bin
To increase brightness, contrast, sharpness by 20% and resize all images (landscape, portrait) to max dimension of 1920 pixels (using largest dimension. hight or width) and compress them to 60% in a given folder while keeping the same aspect ratio.
pillowcover -d /home/user/Pictures/ -b 1.20 -c 1.20 -s 1.20 -r 1920 -q 60
To crop (640*480 from the left corner) and convert (from png to jpg) all images in a folder.
plc -d /home/user/Pictures/ -k "0,0,640,480" -x jpg
usage: pillowcover [-h] [-v] [-d DIR] [-o OUTPUT_DIR] [-b BRIGHTNESS] [-c CONTRAST]
[-s SHARPNESS] [-r RESIZE] [-R RESIZE_RATIO] [-k CROP]
[-q COMPRESSION] [-x EXTENSION]

positional arguments:
image_file Full path to the image file to edit
optional arguments:
-h, --help show this help message and exit
-v, --version show program\'s version number and exit
-d DIR, --dir DIR Path to the directory containing the image files
-o OUTPUT_DIR, --out-dir OUTPUT_DIR
Path to output directory to store edited images. by
default they get stored in (parent
director)/pillowcover-output
-b BRIGHTNESS, --brightness BRIGHTNESS
Change brightness level, 1.00 is the current value
-c CONTRAST, --contrast CONTRAST
Change contrast level, 1.00 is the current value
-s SHARPNESS, --sharpness SHARPNESS
Change sharpness level, 1.00 is the current value
-r RESIZE, --resize RESIZE
Resize img, keep ratio. provide the maximum
length/width value as one number. e.g pillowcase.py
img -r 1920
-R RESIZE_RATIO, --resize-ratio RESIZE_RATIO
Resize img by providing new width and length e.g
pillowcase.py img -R "640 480"
-k CROP, --crop CROP Crop img by providing starting point then width and
length from it e.g pillowcase.py img -k "0,0,640,480"
-q COMPRESSION, --compression-quality COMPRESSION
Compression quality 1-100, 100 means no compression at
all
-x EXTENSION, --extension EXTENSION
Specifiy the output extension. Can be 'jpg', 'jpeg',
'png' Default is same as the input file's. e.g
pillowcase.py -d imgdir -x "jpg"
