Vips – 8.0: Operator index / Alphabetical
Description: Reference for Vips-8.0: Operator index / Alphabetical

#### Operator index / Alphabetical [src]

libvips 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 `VipsObject: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()

libvips 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.

# All libvips operators

This table lists all the libvips 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.
