Get description of image.

Returns

Description or None if not set

fn disclaimer(&self) -> Option<GString>

Get the legal disclaimer.

Returns

Disclaimer or None if not set

fn file_module_name(&self) -> Option<GString>

Return the name registered by the current file module.

Returns

Current file module name or None.

fn resolution_unit(&self) -> ResolutionUnit

Get the units used for resolution.

Returns

a ResolutionUnit.

fn resolution_x(&self) -> f64

Get the X resolution or density in dots per unit.

Returns

X resolution

fn resolution_y(&self) -> f64

Get the Y resolution or density in dots per unit.

Returns

Y resolution

fn software(&self) -> Option<GString>

Get software used to create the image.

Returns

Software or None if not set

fn source(&self) -> Option<GString>

Get device used to create the image.

Returns

source or None if not set

fn string(&self, name: &str) -> Option<GString>

A slightly more efficient version of gegl_metadata_store_get_value() for string values avoiding a duplication. Otherwise it behaves the same gegl_metadata_store_get_value().

name

Metadata name

Returns

String or None.

fn timestamp(&self) -> Option<DateTime>

Get time of original image creation.

Returns

[glib::DateTime][crate::glib::DateTime] or None if not set. Free with g_date_time_unref() when done.

fn title(&self) -> Option<GString>

Get title or caption for image.

Returns

Title or None if not set

fn warning(&self) -> Option<GString>

Get warning.

Returns

Warning or None if not set

fn has_value(&self, name: &str) -> bool

Test whether the MetadataStore contains a value for the specified name.

name

Metadata name

Returns

true if metadata is declared and contains a valid value.

fn set_artist(&self, artist: &str)

Set name of image creator.

artist

Artist string

fn set_comment(&self, comment: &str)

Set the miscellaneous comment; conversion from GIF comment.

comment

Comment string

fn set_copyright(&self, copyright: &str)

Set the copyright notice.

copyright

Copyright string

fn set_description(&self, description: &str)

Set description of image.

description

Description string

fn set_disclaimer(&self, disclaimer: &str)

Set the legal disclaimer.

disclaimer

Disclaimer string

fn set_resolution_unit(&self, unit: ResolutionUnit)

Set the units used for the resolution (density) values.

unit

Units as a ResolutionUnit

fn set_resolution_x(&self, resolution_x: f64)

Set the X resolution or density in dots per unit.

resolution_x

X resolution or density

fn set_resolution_y(&self, resolution_y: f64)

Set the Y resolution or density in dots per unit.

resolution_y

Y resolution or density

fn set_software(&self, software: &str)

Set software used to create the image.

software

Software string

fn set_source(&self, source: &str)

Set device used to create the image.

source

Source string

fn set_string(&self, name: &str, string: &str)

A slightly more efficient version of set_value() for string values avoiding a duplication. Otherwise it behaves the same set_value().

name

Metadata name

string

String value to set

fn set_timestamp(&self, timestamp: &DateTime)

Set time of original image creation.

timestamp

A [glib::DateTime][crate::glib::DateTime]

fn set_title(&self, title: &str)

Set title or caption for image.

title

Title string

fn set_value(&self, name: &str, value: &Value)

Set the specified metadata value. If value is None the default value from the associated [glib::ParamSpec][crate::glib::ParamSpec] is used. This operation will fail if the value has not been previously declared. A changed::name signal is emitted when the value is set. If the value is shadowed by a property a notify::name signal is also emitted.

name

Metadata name

value

(nullable): A valid [glib::Value][crate::glib::Value] or None

fn set_warning(&self, warning: &str)

Set the warning of nature of content.

warning

Warning string

fn typeof_value(&self, name: &str) -> Type

Get the declared type of the value in the MetadataStore.

name

Metadata name

Returns

Declared GType of metadata value or G_TYPE_INVALID.

fn connect_changed<F: Fn(&Self, &ParamSpec) + 'static>( &self, detail: Option<&str>, f: F ) -> SignalHandlerId

::changed is emitted when a metadata value is changed. This is analogous to the GObject::notify signal.

pspec

A [glib::ParamSpec][crate::glib::ParamSpec] declaring the metadata value

fn connect_mapped<F: Fn(&Self, &str, bool) + 'static>( &self, f: F ) -> SignalHandlerId

::mapped is emitted after a file module registers a mapping and before other processing takes place. An application may respond to the signal by registering additional mappings or overriding existing values, for example it might override the TIFF ImageDescription tag to format multiple metadata values into the description.

file_module

The file module name

exclude_unmapped

true if the file module cannot handle unmapped values

fn connect_unmapped<F: Fn(&Self, &str, &str) + 'static>( &self, f: F ) -> SignalHandlerId

::unmapped is emitted when a file module tries to look up an unmapped metadata name. When the handler returns a second attempt is made to look up the metadata.

file_module

The file module name

local_name

The unmapped metadata name as used by the file module

fn connect_artist_notify<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

fn connect_comment_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

fn connect_description_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

fn connect_disclaimer_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

fn connect_software_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

fn connect_source_notify<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

fn connect_timestamp_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId
