COMMAND LINE ARGUMENTS
-q, --quality [value]
{Required}
Sets the quality of the image. The higher the value is, better the result will be. Note that a value of 0 will mean lossless compression, which will not modify the original image, but will compress less. Allowed range is [0. 100].
A common value for lossy compression is 80.-e, --exif
Keeps the JPEG metadata information during compression. File size will be slightly higher.-o, --output [value]
{Required}
Path to the output folder where the compressed files will be stored. Can be the same input folder, which will overwrite the original files.-R, --recursive
If the input is a folder, caesiumclt will also scan every subfolder searching for images.
Note that this may end up building a large set of files to be compressed and should be used carefully.-S, --keep-structure
If the input is a folder, and the-R
option is set, caesiumclt will compress all the files keeping the original folder structure.-O, --overwrite
Sets overwrite policy:all
will overwrite any existing file,prompt
will ask each time before overwriting,bigger
will overwrite bigger files only, andnone
will silently skip existing files.-d, --dry-run
If this option is set, no files will be compressed, but the entire process will just be simulated.
Useful for checking if all the files will be correctly handled.-Q, --quiet
Suppress all output. Output from the libcaesium library will still be outputted.-h, --help
Displays a summary of the command line arguments, much like this one you're reading.-v, --version
