Vips.Argument
Description: Reference for Vips.Argument

### Struct

# VipsArgument

#### Description [src]

    struct VipsArgument {
      GParamSpec* pspec;
    }

Libvips has a simple mechanism for automating at least some aspects of `GObject` properties. You add a set of macros to your `_class_init()` which describe the arguments, and set the get and set functions to the libvips ones.

See extending for a complete example.
