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. EXAMPLES
Run a vips7 operation. The vips7 interface does not suport optional arguments. $ 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) RETURN VALUE
returns 0 on success and non-zero on error. SEE ALSO

Module::Loaded - mark modules as loaded or unloaded SYNOPSIS
use Module::Loaded; $bool = mark_as_loaded('Foo'); # is now marked as loaded $loc = is_loaded('Foo'); # location of set to the # loaders location eval "require 'Foo'"; # is now a no-op $bool = mark_as_unloaded('Foo'); # no longer marked as loaded eval "require 'Foo'"; # Will try to find in @INC DESCRIPTION
When testing applications, often you find yourself needing to provide functionality in your test environment that would usually be provided by external modules. Rather than munging the %INC by hand to mark these external modules as loaded, so they are not attempted to be loaded by perl, this module offers you a very simple way to mark modules as loaded and/or unloaded. FUNCTIONS
$bool = mark_as_loaded( PACKAGE ); Marks the package as loaded to perl. "PACKAGE" can be a bareword or string. If the module is already loaded, "mark_as_loaded" will carp about this and tell you from where the "PACKAGE" has been loaded already. $bool = mark_as_unloaded( PACKAGE ); Marks the package as unloaded to perl, which is the exact opposite of "mark_as_loaded". "PACKAGE" can be a bareword or string. If the module is already unloaded, "mark_as_unloaded" will carp about this and tell you the "PACKAGE" has been unloaded already. $loc = is_loaded( PACKAGE ); "is_loaded" tells you if "PACKAGE" has been marked as loaded yet. "PACKAGE" can be a bareword or string. It returns falls if "PACKAGE" has not been loaded yet and the location from where it is said to be loaded on success. BUG REPORTS
