VIPS(1) 						      General Commands Manual							   VIPS(1)

NAME
       vips - run vips operations from the command line

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 function
       database, and to maintain parts of the VIPS library.

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

	 $ vips im_invert lena.v lena2.v

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

       -v, --version
	      Show VIPS version.

COMMANDS
       list PACKAGE
	      List operations defined in PACKAGE. PACKAGE can also be "classes", "packages" or "all".

       cpph PACKAGE
	      Print C++ header for PACKAGE. PACKAGE can also be a function name, or "all".

       cppc PACKAGE
	      Print C++ binding for PACKAGE. PACKAGE can also be a function name, or "all".

       operation-name operation-arguments
	      Execute  a named operation, for example im_invert, or add. Names prefixed with "im_" are called via the vips7 interface, names with-
	      out the prefix use the new vips8 interface.

	 $ vips im_invert lena.v lena2.v

       Run a vips8 operation. Operation options must follow the operation name.

	 $ vips add --imtest=option.jpg lena.v lena2.v out.v

       Get a "usage" message for an operation

	 $ vips add
	 VipsAdd (add), add two images
	   add left right out
	 where:
	   left :: VipsImage (input)
	   right :: VipsImage (input)
	   out :: VipsImage (output)
	 optional arguments:
	   imtest :: VipsImage (input)
	   booltest :: gboolean (input)
