Siril is an image processing tool specially tailored for noise reduction and improving the signal/noise ratio of an image from multiple captures, as required in astronomy. Siril can align, stack and enhance pictures from various file formats, even image sequences (movies and SER files). It makes use of OpenMP, supports all the cameras supported by libraw, and carries out its calculations in a high precision 32-bit floating point engine.
-i Starts Siril with configuration file which path is given in conf_file -f (or --format) Prints all supported image input formats, depend‐ ing on the libraries detected at compile-time -v (or --version) Prints program name and version and exits -c (or --copyright) Prints copyright and exits -h (or --help) Short usage help -p Starts Siril without the graphical user interface and use the named pipes to accept commands and print logs and status infor‐ mation. On POSIX systems, the named pipes are created in /tmp/siril_commands.in and /tmp/siril_commands.out -r (or --inpipe) Provide an alternative path for the input pipe that receives the commands, if -p is passed. The pipe can be create by an external program with the mkfifo(1) command -w (or --outpipe) Provide an alternative path for the output pipe that prints logs and status updates, if -p is passed. The pipe can be create by an external program with the mkfifo(1) command -d (or --directory) Setting argument in cwd -s (or --script) Starts Siril without the graphical user interface and run a script instead. Scripts are text files that contain a list of commands to be executed sequentially. In these files, lines starting with a # are considered as comments. image_file_to_open Open an image or sequence file right after start-up
~/.config/siril/siril.cfg User preferences. Overridden by the -i option. ~/.siril/siril.css The stylesheet used to change colours of the graphical user in‐ terface. This is useful for personalisation or if a GTK theme is incompatible with some coloured elements of Siril.
