Processing Controls

The CLI will use your Autopilot settings to process images. Open Topaz Photo AI and go to the Preferences > Autopilot menu.

Instructions on using the Preferences > Autopilot menu are here.

Command Options

--output, -o: Output folder to save images to. If it doesn't exist the program will attempt to create it.

--overwrite: Allow overwriting of files. THIS IS DESTRUCTIVE.

--recursive, -r: If given a folder path, it will recurse into subdirectories instead of just grabbing top level files.
Note: If output folder is specified, the input folder's structure will be recreated within the output as necessary.

File Format Options:

--format, -f: Set the output format. Accepts jpg, jpeg, png, tif, tiff, dng, or preserve. Default: preserve
Note: Preserve will attempt to preserve the exact input extension, but RAW files will still be converted to DNG.Format Specific Options:

--quality, -q: JPEG quality for output. Must be between 0 and 100. Default: 95

--compression, -c: PNG compression amount. Must be between 0 and 10. Default: 2

--bit-depth, -d: TIFF bit depth. Must be either 8 or 16. Default: 16

--tiff-compression: -tc: TIFF compression format. Must be "none", "lzw", or "zip".
Note: lzw is not allowed on 16-bit output and will be converted to zip.

Debug Options:

--showSettings: Shows the Autopilot settings for images before they are processed

--skipProcessing: Skips processing the image (e.g., if you just want to know the settings)

--verbose, -v: Print more log entries to console.

Return values:
0 - Success
1 - Partial Success (e.g., some files failed)
-1 (255) - No valid files passed.
-2 (254) - Invalid log token. Open the app normally to login.
-3 (253) - An invalid argument was found.
