SYNOPSIS

vips [options] [command] [command-options] [command-args]

DESCRIPTION

vips(1) is the VIPS universal main program. You can use it to run any VIPS operation from the command line, to query the VIPS class hierarchy, and to maintain parts of the VIPS library.

To run a VIPS operation, the first argument should be the name of the operation and following arguments should be the operation arguments. For example:

$ vips invert lena.v lena2.v

OPTIONS

-l BASE-NAME, --list=BASE-NAME
  List operations below BASE-NAME. This prints a one-line summary of every operation in vips below the class BASE-NAME, where BASE-NAME may be a full vips class name, or a nickname.

If BASE-NAME is not supplied, this will list all classes below VipsOperation.

-p PLUGIN, --plugin=PLUGIN
  Load PLUGIN. Note that plugins in $VIPSHOME/lib/vips-plugins-MAJOR.MINOR are loaded automatically.

-v, --version
  Show VIPS version.

COMMANDS

operation-name operation-arguments
  Execute a named operation, for example add.
