Title: Operator index / Alphabetical

libvips has a set of operators, each of which computes some useful image
processing operation. Each operator is implemented as a [class@GObject.Object]
class, for example `VipsGamma`. Classes are identified by their unique
[property@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++:

```c++
vips::VImage fred = ...;
vips::VImage jim = fred.gamma();
```

or Python:

```python
fred = jim.gamma()
```

libvips has a set of C wrapper functions for calling operators, in this
case [method@Image.gamma]:

```c
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.
