python >= 3.5, pillow
Installation

# Add to PATH to Install and run programs with "pip install --user"
export PATH=$PATH:~/.local/binUsage
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 60To 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 jpgUsage Options

optional arguments:
-h, --help show this help message and exit
-v, --version show program\'s version number and exit
-i IMAGE_FILE, --img IMAGE_FILE
Path to the image file to edit
-d IMAGE_DIR, --dir IMAGE_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
