## Member Function Documentation

Glib::ustring Gdk::PixbufFormat::get_description | ( |  | ) | const

Returns a description of the format.

Since gtkmm 2.2:

Returns
  A description of the format.

std::vector<Glib::ustring> Gdk::PixbufFormat::get_extensions | ( |  | ) | const

Returns the filename extensions typically used for files in the given format.

Since gtkmm 2.2:

Returns
  A `0`-terminated array of filename extensions which must be freed with Glib::strfreev() when it is no longer needed.

Glib::ustring Gdk::PixbufFormat::get_license | ( |  | ) | const

Returns information about the license of the image loader for the format.

The returned string should be a shorthand for a wellknown license, e.g. "LGPL", "GPL", "QPL", "GPL/QPL", or "other" to indicate some other license. This string should be freed with Glib::free() when it's no longer needed.

Since gtkmm 2.6:

Returns
  A string describing the license of format.

std::vector<Glib::ustring> Gdk::PixbufFormat::get_mime_types | ( |  | ) | const

Returns the mime types supported by the format.

Since gtkmm 2.2:

Returns
  A `0`-terminated array of mime types which must be freed with Glib::strfreev() when it is no longer needed.

Glib::ustring Gdk::PixbufFormat::get_name | ( |  | ) | const

Returns the name of the format.

Since gtkmm 2.2:

Returns
  The name of the format.

static GType Gdk::PixbufFormat::get_type | ( |  | ) |

static

Get the GType for this class, for use with the underlying GObject type system.

GdkPixbufFormat* Gdk::PixbufFormat::gobj | ( |  | ) |

inline

Provides access to the underlying C instance.

const GdkPixbufFormat* Gdk::PixbufFormat::gobj | ( |  | ) | const

inline

Provides access to the underlying C instance.

GdkPixbufFormat* Gdk::PixbufFormat::gobj_copy | ( |  | ) | const

Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.

bool Gdk::PixbufFormat::is_disabled | ( |  | ) | const

Returns whether this image format is disabled.

See set_disabled().

Since gtkmm 2.6:

Returns
  Whether this image format is disabled.

bool Gdk::PixbufFormat::is_scalable | ( |  | ) | const

Returns whether this image format is scalable.

If a file is in a scalable format, it is preferable to load it at the desired size, rather than loading it at the default size and scaling the resulting pixbuf to the desired size.

Since gtkmm 2.6:

Returns
  Whether this image format is scalable.

bool Gdk::PixbufFormat::is_writable | ( |  | ) | const

Returns whether pixbufs can be saved in the given format.

Since gtkmm 2.2:

Returns
  Whether pixbufs can be saved in the given format.

PixbufFormat& Gdk::PixbufFormat::operator= | ( | const PixbufFormat& | other | ) |

void Gdk::PixbufFormat::set_disabled | ( | bool | disabled = `true` | ) |

Disables or enables an image format.

If a format is disabled, gdk-pixbuf won't use the image loader for this format to load images. Applications can use this to avoid using image loaders with an inappropriate license, see get_license().

Since gtkmm 2.6:

Parameters

  disabled | `true` to disable the format format.

void Gdk::PixbufFormat::swap | ( | PixbufFormat& | other | ) |

## Friends And Related Function Documentation

|  | PixbufFormat& | rhs
| ) |  |

Parameters

  lhs | The left-hand side
  rhs | The right-hand side

Gdk::PixbufFormat wrap | ( | GdkPixbufFormat * | 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.
