## Detailed Description

A Wrapper for the videoscale plugin.

Please note that, though using the underlying GObject is fine, using its C type is not guaranteed to be API stable across releases because it is not guaranteed to always remain the same. Also, not all plug-ins are available on all systems so care must be taken that they exist before they are used, otherwise there will be errors and possibly a crash.

Glib::PropertyProxy<bool> Gst::VideoScale::property_add_borders | ( | ) |

Add black borders if necessary to keep the display aspect ratio.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<bool> Gst::VideoScale::property_add_borders | ( | ) | const

Add black borders if necessary to keep the display aspect ratio.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

## Friends And Related Function Documentation

Glib::RefPtr< Gst::VideoScale > wrap | ( | GstVideoScale * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
