Image processing tool for astronomy and other applications

Siril is a powerful image processing tool designed for improving the signal-to-noise ratio of astronomical images. It offers a wide range of tools for aligning, stacking, and enhancing images from various file formats, including image sequences. It features a high-precision 32-bit floating-point engine and supports parallel processing to run quickly.
The application is divided into 2 binaries. The first one, siril, launches the program in graphic mode. The second one, siril-cli, is a command line interface allowing to execute the following options.
-v, --version
Prints the program name and version, then exits.
-i conf_file
Starts Siril with the specified configuration file.
-f, --format
Prints all supported input image formats, depending on the libraries detected at compile-time.
-c, --copyright
Prints copyright information, then exits.
-h, --help
Displays a brief usage summary.
-p
Starts Siril without the graphical user interface and uses named pipes to accept commands and print logs and status information. On POSIX systems, the named pipes are created in /tmp/siril_commands.in and /tmp/siril_commands.out.
-r input_pipe_path, --inpipe=input_pipe_path
Provides an alternative path for the input pipe that receives the commands if -p is passed. The pipe can be created by an external program with the mkfifo(1) command.
-w output_pipe_path, --outpipe=output_pipe_path
Provides an alternative path for the output pipe that prints logs and status updates if -p is passed. The pipe can be created by an external program with the mkfifo(1) command.
-d working_directory, --directory=working_directory
Sets the specified path as the current working directory.
-s script_file, --script=script_file
Starts Siril without the graphical user interface and runs the specified 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. If this option is not passed, pipe operation is assumed as if -p had been passed.
-s -
Redirects inputs written after - to stdin.
fileOpens the specified image or sequence file immediately after startup.

User preferences that can be overridden by the -i option.
/usr/share/siril/siril.css
The style sheet used to change the look of the graphical user interface. This is useful for customization or if a GTK theme is incompatible with some colored elements of Siril.
