VIPS function listUsing VIPS — List of VIPS functions and operators |
VIPS has a set of operators each of which computes some useful image
processing operation. Each operator is
implemented as a GObject class, for example VipsGamma.
Classes are identified by their unique nickname, in this
case gamma.
From the command-line, C++ and most language bindings, you use the
nickname to call the operator. For example in C++:
vips::VImage fred = ...; vips::VImage jim = fred.gamma();
or Python:
fred = jim.gamma()
VIPS has a set of C wrapper functions for calling operators, in this
case vips_gamma():
VipsImage *fred = ...;
VipsImage *jim;
if (vips_gamma(fred, &jim, NULL))
...error;
Some operators have many C convenience functions.
This table lists all the VIPS operators with their C convenience functions and a short description. It's supposed to be useful for searching. See the API docs each function links to for more details.
