NAME

6       vips - run vips function from UNIX command line
7

SYNOPSIS

9       vips [flags] [command] [args]
10

DESCRIPTION

12       vips is the VIPS universal main program. You can use it to run any VIPS
13       function from the UNIX command line, to query the VIPS  function  data‐
14       base, and to maintain parts of the VIPS library.
15
16       To  run  a  VIPS function, the first argument should be the name of the
17       function and following arguments should be the function parameters. For
18       example:
19
20         example% vips im_invert lena.v lena2.v
21
22       To  query  the  VIPS function database, use "-help", then the name of a
23       function or a package. For example:
24
25         example% vips -help
26         "-help flags" for a list of flags available
27         "-help <package name>" for a list of commands in package
28         where <package name> is one of:
29           arithmetic (31 functions)
30           boolean (8 functions)
31           colour (24 functions)
32           ... etc
33           relational (13 functions)
34         "-help all" for a list of all commands in all packages
35         "-help <command>" for an explanation of a command
36         example% vips -help arithmetic
37         functions available in package "arithmetic":
38         im_abs      - absolute value
39         im_acostra  - acos of image (result in degrees)
40         ... etc
41         im_stats    - many image statistics in one pass
42         im_tantra   - tan of image (angles in degrees)
43         example% vips -help im_abs
44         vips: args: in out
45         where:
46           in is of type "image"
47           out is of type "image"
48         absolute value, from package "arithmetic"
49         flags: (PIO function) (no coordinate transformation)
50         example%

OPTIONS

54       -help  simple built-in help system can give information on arguments to
55              the vips program, on argumets to any VIPS function, or a listing
56              of the functions available.
57
58       -plugin <file name>
59              Add commands in file to those normally  available.  Plugins  are
60              searched  before  the  main  VIPS function database, letting you
61              override standard VIPS functions.
62
63       -links Print "ln -s" lines for all VIPS functions. Used  to  build  the
64              VIPS bin area.
65
66       -ip <package name>
67              Print  ip macros for the functions in the named package. Used to
68              build the ip menu system.
69
70       -c++ <package name/function name/all>
71              Print C++ bindings for a function, for a  package,  or  for  all
72              functions. Used to build the VImage class.
73

RETURN VALUE

75       returns 0 on success and non-zero on error.
