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: plc [-h] [-v] [-i IMAGE_FILE] [-d IMAGE_DIR] [-o OUTPUT_DIR] [-b BRIGHTNESS] [-c CONTRAST] [-s SHARPNESS] [-r RESIZE] [-R RESIZE_RATIO] [-k CROP] [-q COMPRESSION] [-x EXTENSION] PillowCover: Mass Manipulate Images Using Python: Change Brightness, Contrast, Sharpness, Resize, Compress, Crop and Convert. A simple script (wrapper) using pillow. Licensed Under: GNU General Public License v3 or later (GPLv3+) 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 pillowcase.py -d imgdir -x "jpg"
