name: string

Methods

  • addAnnot(annot: Annot): void
  • Creates a binding between source_property on source and target_property on target.

    Whenever the source_property is changed the target_property is updated using the same value. For instance:

      g_object_bind_property (action, "active", widget, "sensitive", 0);
    

    Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.

    If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well.

    The binding will automatically be removed when either the source or the target instances are finalized. To remove the binding without affecting the source and the target you can just call g_object_unref() on the returned #GBinding instance.

    Removing the binding by calling g_object_unref() on it must only be done if the binding, source and target are only used from a single thread and it is clear that both source and target outlive the binding. Especially it is not safe to rely on this if the binding, source or target can be finalized from different threads. Keep another reference to the binding and use g_binding_unbind() instead to be on the safe side.

    A #GObject can have multiple bindings.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    Returns Binding

  • Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

    This function is the language bindings friendly version of g_object_bind_property_full(), using #GClosures instead of function pointers.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transformTo: TClosure<any, any>

      a #GClosure wrapping the transformation function from the source to the target, or %NULL to use the default

    • transformFrom: TClosure<any, any>

      a #GClosure wrapping the transformation function from the target to the source, or %NULL to use the default

    Returns Binding

  • connect(sigName: "notify::label", callback: ((...args: any[]) => void)): number
  • connect(sigName: string, callback: ((...args: any[]) => void)): number
  • Parameters

    • sigName: "notify::label"
    • callback: ((...args: any[]) => void)
        • (...args: any[]): void
        • Parameters

          • Rest ...args: any[]

          Returns void

    Returns number

  • Parameters

    • sigName: string
    • callback: ((...args: any[]) => void)
        • (...args: any[]): void
        • Parameters

          • Rest ...args: any[]

          Returns void

    Returns number

  • emit(sigName: "notify::label", ...args: any[]): void
  • emit(sigName: string, ...args: any[]): void
  • Finds text in page with the default options (%POPPLER_FIND_DEFAULT) and returns a #GList of rectangles for each occurrence of the text on the page. The coordinates are in PDF points.

    Parameters

    • text: string

      the text to search for (UTF-8 encoded)

    Returns Poppler.Rectangle[]

  • Finds text in page with the given #PopplerFindFlags options and returns a #GList of rectangles for each occurrence of the text on the page. The coordinates are in PDF points.

    Parameters

    • text: string

      the text to search for (UTF-8 encoded)

    • options: Poppler.FindFlags

      find options

    Returns Poppler.Rectangle[]

  • forceFloating(): void
  • This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().

    Returns void

  • freezeNotify(): void
  • Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.

    This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

    Returns void

  • Returns a list of #PopplerAnnotMapping items that map from a location on page to a #PopplerAnnot. This list must be freed with poppler_page_free_annot_mapping() when done.

    Returns AnnotMapping[]

  • getData(key?: string): object
  • Gets a named field from the objects table of associations (see g_object_set_data()).

    Parameters

    • Optional key: string

      name of the key for that association

    Returns object

  • getDuration(): number
  • Returns a list of #PopplerFormFieldMapping items that map from a location on page to a form field. This list must be freed with poppler_page_free_form_field_mapping() when done.

    Returns FormFieldMapping[]

  • Returns a list of #PopplerImageMapping items that map from a location on page to an image of the page. This list must be freed with poppler_page_free_image_mapping() when done.

    Returns ImageMapping[]

  • getIndex(): number
  • getLabel(): string
  • Returns the label of page. Note that page labels and page indices might not coincide.

    Returns string

  • Returns a list of #PopplerLinkMapping items that map from a location on page to a #PopplerAction. This list must be freed with poppler_page_free_link_mapping() when done.

    Returns LinkMapping[]

  • getProperty(propertyName?: string, value?: any): void
  • Gets a property of an object.

    The value can be:

    • an empty #GValue initialized by %G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a #GValue initialized with the expected type of the property
    • a #GValue initialized with a type to which the expected type of the property can be transformed

    In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().

    Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.

    Parameters

    • Optional propertyName: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • getQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • Returns a region containing the area that would be rendered by poppler_page_render_selection(). The returned region must be freed with cairo_region_destroy()

    Parameters

    Returns cairo.Region

  • Returns a region containing the area that would be rendered by poppler_page_render_selection() as a #GList of #PopplerRectangle. The returned list must be freed with poppler_page_selection_region_free().

    Parameters

    Returns Poppler.Rectangle[]

  • getSize(): [number, number]
  • Gets the size of page at the current scale and rotation.

    Returns [number, number]

  • getText(): string
  • Obtains the attributes of the text as a #GList of #PopplerTextAttributes. This list must be freed with poppler_page_free_text_attributes() when done.

    Each list element is a #PopplerTextAttributes struct where start_index and end_index indicates the range of text (as returned by poppler_page_get_text()) to which text attributes apply.

    See also poppler_page_get_text_attributes_for_area()

    Returns Poppler.TextAttributes[]

  • Obtains the attributes of the text in area as a #GList of #PopplerTextAttributes. This list must be freed with poppler_page_free_text_attributes() when done.

    Each list element is a #PopplerTextAttributes struct where start_index and end_index indicates the range of text (as returned by poppler_page_get_text_for_area()) to which text attributes apply.

    Parameters

    Returns Poppler.TextAttributes[]

  • Obtains the layout of the text as a list of #PopplerRectangle This array must be freed with g_free() when done.

    The position in the array represents an offset in the text returned by poppler_page_get_text()

    See also poppler_page_get_text_layout_for_area().

    Returns [boolean, Poppler.Rectangle[]]

  • Obtains the layout of the text contained in area as a list of #PopplerRectangle This array must be freed with g_free() when done.

    The position in the array represents an offset in the text returned by poppler_page_get_text_for_area()

    Parameters

    Returns [boolean, Poppler.Rectangle[]]

  • Get the embedded thumbnail for the specified page. If the document doesn't have an embedded thumbnail for the page, this function returns %NULL.

    Returns cairo.Surface

  • getThumbnailSize(): [boolean, number, number]
  • Returns %TRUE if page has a thumbnail associated with it. It also fills in width and height with the width and height of the thumbnail. The values of width and height are not changed if no appropriate thumbnail exists.

    Returns [boolean, number, number]

  • getv(names: string[], values: any[]): void
  • Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • isFloating(): boolean
  • notify(propertyName: string): void
  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    Parameters

    • propertyName: string

      the name of a property installed on the class of object.

    Returns void

  • Emits a "notify" signal for the property specified by pspec on object.

    This function omits the property name lookup, hence it is faster than g_object_notify().

    One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:

      enum
    {
    PROP_0,
    PROP_FOO,
    PROP_LAST
    };

    static GParamSpec *properties[PROP_LAST];

    static void
    my_object_class_init (MyObjectClass *klass)
    {
    properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
    0, 100,
    50,
    G_PARAM_READWRITE);
    g_object_class_install_property (gobject_class,
    PROP_FOO,
    properties[PROP_FOO]);
    }

    and then notify a change on the "foo" property with:

      g_object_notify_by_pspec (self, properties[PROP_FOO]);
    

    Parameters

    • pspec: ParamSpec

      the #GParamSpec of a property installed on the class of object.

    Returns void

    • Optional after: boolean

    Returns EventEmitter

  • Increases the reference count of object.

    Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type of object will be propagated to the return type (using the GCC typeof() extension), so any casting the caller needs to do on the return type must be explicit.

    Returns GObject.Object

  • Increase the reference count of object, and possibly remove the [floating][floating-ref] reference, if object has a floating reference.

    In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.

    Since GLib 2.56, the type of object will be propagated to the return type under the same conditions as for g_object_ref().

    Returns GObject.Object

  • removeAnnot(annot: Annot): void
  • Render the page to the given cairo context. This function is for rendering a page that will be displayed. If you want to render a page that will be printed use poppler_page_render_for_printing() instead. Please see the documentation for that function for the differences between rendering to the screen and rendering to a printer.

    Parameters

    Returns void

  • Render the page to the given cairo context for printing with #POPPLER_PRINT_ALL flags selected. If you want a different set of flags, use poppler_page_render_for_printing_with_options().

    The difference between poppler_page_render() and this function is that some things get rendered differently between screens and printers:

    PDF annotations get rendered according to their #PopplerAnnotFlag value. For example, #POPPLER_ANNOT_FLAG_PRINT refers to whether an annotation is printed or not, whereas #POPPLER_ANNOT_FLAG_NO_VIEW refers to whether an annotation is invisible when displaying to the screen. PDF supports "hairlines" of width 0.0, which often get rendered as having a width of 1 device pixel. When displaying on a screen, Cairo may render such lines wide so that they are hard to see, and Poppler makes use of PDF's Stroke Adjust graphics parameter to make the lines easier to see. However, when printing, Poppler is able to directly use a printer's pixel size instead. Some advanced features in PDF may require an image to be rasterized before sending off to a printer. This may produce raster images which exceed Cairo's limits. The "printing" functions will detect this condition and try to down-scale the intermediate surfaces as appropriate.

    Parameters

    Returns void

  • Render the page to the given cairo context for printing with the specified options

    See the documentation for poppler_page_render_for_printing() for the differences between rendering to the screen and rendering to a printer.

    Parameters

    Returns void

  • Render the selection specified by selection for page to the given cairo context. The selection will be rendered, using glyph_color for the glyphs and background_color for the selection background.

    If non-NULL, old_selection specifies the selection that is already rendered to cairo, in which case this function will (some day) only render the changed part of the selection.

    Parameters

    Returns void

  • renderToPs(psFile: PSFile): void
  • runDispose(): void
  • Releases all references to other objects. This can be used to break reference cycles.

    This function should only be called from object system implementations.

    Returns void

  • setData(key: string, data?: object): void
  • Each object carries around a table of associations from strings to pointers. This function lets you set an association.

    If the object already had an association with that name, the old association will be destroyed.

    Internally, the key is converted to a #GQuark using g_quark_from_string(). This means a copy of key is kept permanently (even after object has been finalized) — so it is recommended to only use a small, bounded set of values for key in your program, to avoid the #GQuark storage growing unbounded.

    Parameters

    • key: string

      name of the key

    • Optional data: object

      data to associate with that key

    Returns void

  • setProperty(propertyName: string, value?: any): void
  • Sets a property on an object.

    Parameters

    • propertyName: string

      the name of the property to set

    • Optional value: any

      the value

    Returns void

  • stealData(key?: string): object
  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • Optional key: string

      name of the key

    Returns object

  • stealQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata() and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:

    void
    object_add_to_user_list (GObject *object,
    const gchar *new_string)
    {
    // the quark, naming the object data
    GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
    // retrieve the old string list
    GList *list = g_object_steal_qdata (object, quark_string_list);

    // prepend new string
    list = g_list_prepend (list, g_strdup (new_string));
    // this changed 'list', so we need to set it again
    g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
    }
    static void
    free_string_list (gpointer data)
    {
    GList *node, *list = data;

    for (node = list; node; node = node->next)
    g_free (node->data);
    g_list_free (list);
    }

    Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • thawNotify(): void
  • Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.

    Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.

    It is an error to call this function when the freeze count is zero.

    Returns void

  • unref(): void
  • Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

    If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.

    Returns void

  • watchClosure(closure: TClosure<any, any>): void
  • This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

    Parameters

    • closure: TClosure<any, any>

      #GClosure to watch

    Returns void

  • compatControl(what: number, data: object): number
  • Frees a list of #PopplerAnnotMappings allocated by poppler_page_get_annot_mapping(). It also unreferences the #PopplerAnnots that each mapping contains, so if you want to keep them around, you need to reference them with g_object_ref().

    Parameters

    Returns void

  • Frees a list of #PopplerFormFieldMappings allocated by poppler_page_get_form_field_mapping().

    Parameters

    Returns void

  • Frees a list of #PopplerImageMappings allocated by poppler_page_get_image_mapping().

    Parameters

    Returns void

  • Frees a list of #PopplerLinkMappings allocated by poppler_page_get_link_mapping(). It also frees the #PopplerActions that each mapping contains, so if you want to keep them around, you need to copy them with poppler_action_copy().

    Parameters

    Returns void

  • Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    • propertyName: string

      name of a property to look up.

    Returns ParamSpec

  • Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.

    This function is meant to be called from the interface's default vtable initialization function (the class_init member of #GTypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface.

    If pspec is a floating reference, it will be consumed.

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface.

    • pspec: ParamSpec

      the #GParamSpec for the new property

    Returns void

  • Lists the properties of an interface.Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    Returns ParamSpec[]

  • Creates a new instance of a #GObject subtype and sets its properties.

    Construction parameters (see %G_PARAM_CONSTRUCT, %G_PARAM_CONSTRUCT_ONLY) which are not explicitly specified are set to their default values.

    Parameters

    • objectType: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object
