NAME¶

ctsim — A Graphical Computed Tomography Simulator

SYNOPSIS¶

DESCRIPTION¶

ctsim is a graphical user interface to the various components of the CTSim package. The home for CTSim is http://www.ctsim.org.

ctsim also runs those components from the command line, without opening a window. Naming a function first runs that function and exits, with its output on the standard output and its exit code as the program's:

and --shell reads functions from a prompt instead. The decision is made before the graphical interface is started, so a function runs on a machine with no display. ctsim-nogui(1) is the same program built without the interface, for a machine with no Qt at all; it offers the same functions and the same shell. The functions are each installed under their own name as well, so

OPTIONS¶

--workdir directory

The directory a script writes what it makes into, made if it does not exist. Without this option a directory named ctsim-work- and the time is made under the system temporary directory, and removed when CTSim exits.

--script-save

When the script ends, save every window it made into the work directory, each under a name made from its title, and copy the script beside them. With --workdir the directory then holds everything needed to see what a run did and to do it again.

--script-ignore-errors

Exit zero even where a script command fails. Without it a script that fails exits non-zero, so a demonstration that has quietly stopped working is noticed.

--script file

Run a script of interface commands and exit with its result. The manual's Scripts section lists the commands; scripts/demos/intro.ctsim is an example.

--cwd directory

The directory the file dialogs open in, and the one a script's relative paths are taken from. Useful on macOS, where an application bundle is started with the root of the volume as its working directory.

--no-splash

Do not show the splash screen. A script run wants the windows it makes, not two seconds of logo in front of them.

--verbose

Verbose logging.

--legacy-format

Write CTSim's legacy binary file format instead of HDF5. The legacy format carries no history and cannot hold a plot's ranges; it is here for writing files that can be read by CTSim versions prior to 6.5.0.

--version

Display version

--help

Print a terse help message
