Sets our main struct and passes it to the parent class.
Returns a new rsvg handle. Must be freed with @g_object_unref. This handle can be used for dynamically loading an image. You need to feed it data using @rsvg_handle_write, then call @rsvg_handle_close when done. Afterwords, you can render it using Cairo or get a GdkPixbuf from it. When finished, free with g_object_unref(). No more than one image can be loaded with one handle.
Loads the SVG specified by @data.
Loads the SVG specified by @file_name.
Creates a new #RsvgHandle for @file.
Creates a new #RsvgHandle for @stream.
Creates a new #RsvgHandle with flags @flags.
Closes @handle, to indicate that loading the image is complete. This will return %TRUE if the loader closed successfully. Note that @handle isn't freed until @g_object_unref is called.
Gets the base uri for this #RsvgHandle.
Get the SVG's size. Do not call from within the size_func callback, because an infinite loop will occur.
Get the size of a subelement of the SVG file. Do not call from within the size_func callback, because an infinite loop will occur.
Get the main Gtk struct
Returns the pixbuf loaded by @handle. The pixbuf returned will be reffed, so the caller of this function must assume that ref. If insufficient data has been read to create the pixbuf, or an error occurred in loading, then %NULL will be returned. Note that the pixbuf may not be complete until @rsvg_handle_close has been called.
Creates a #GdkPixbuf the same size as the entire SVG loaded into @handle, but only renders the sub-element that has the specified @id (and all its sub-sub-elements recursively). If @id is #NULL, this function renders the whole SVG.
Get the position of a subelement of the SVG file. Do not call from within the size_func callback, because an infinite loop will occur.
the main Gtk struct as a void*
Checks whether the element @id exists in the SVG document.
Reads @stream and writes the data from it to @handle.
Draws a loaded SVG handle to a Cairo context. Drawing will occur with respect to the @cr's current transformation: for example, if the @cr has a rotated current transformation matrix, the whole SVG will be rotated in the rendered version.
Draws a subset of a loaded SVG handle to a Cairo context. Drawing will occur with respect to the @cr's current transformation: for example, if the @cr has a rotated current transformation matrix, the whole SVG will be rotated in the rendered version.
Set the base URI for @handle from @file. Note: This function may only be called before rsvg_handle_write() or rsvg_handle_read_stream_sync() has been called.
Set the base URI for this SVG. This can only be called before rsvg_handle_write() has been called.
Sets the DPI for the outgoing pixbuf. Common values are 75, 90, and 300 DPI. Passing a number <= 0 to @dpi will reset the DPI to whatever the default value happens to be.
Sets the DPI for the outgoing pixbuf. Common values are 75, 90, and 300 DPI. Passing a number <= 0 to #dpi_x or @dpi_y will reset the DPI to whatever the default value happens to be.
Loads the next @count bytes of the image. This will return %TRUE if the data was loaded successful, and %FALSE if an error occurred. In the latter case, the loader will be closed, and will not accept further writes. If %FALSE is returned, @error will be set to an error from the #RsvgError domain. Errors from #GIOErrorEnum are also possible.
This function should not be called from normal programs. See xmlCleanupParser() for more information.
Do not use this function. Create an #RsvgHandle and call rsvg_handle_set_dpi() on it instead.
Do not use this function. Create an #RsvgHandle and call rsvg_handle_set_dpi_x_y() on it instead.

Gets a D Object from the objects table of associations.
The notify signal is emitted on an object when one of its properties has been changed. Note that getting this signal doesn't guarantee that the value of the property has actually changed, it may also be emitted when the setter for the property is called to reinstate the previous value.
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().
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.
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().
Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established.
Adds a weak reference from weak_pointer to @object to indicate that the pointer located at @weak_pointer_location is only valid during the lifetime of @object. When the @object is finalized, @weak_pointer will be set to %NULL.
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:
Complete version of g_object_bind_property().
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 is a variant of g_object_get_data() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
This is a variant of g_object_get_qdata() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.
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().
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.
Gets a named field from the objects table of associations (see g_object_set_data()).
Gets a property of an object.
This function gets back user data pointers stored via g_object_set_qdata().
Gets properties of an object.
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.
Checks whether @object has a floating[floating-ref] reference.
Emits a "notify" signal for the property @property_name on @object.
Emits a "notify" signal for the property specified by @pspec on @object.
Increases the reference count of @object.
Increase the reference count of @object, and possibly remove the floating[floating-ref] reference, if @object has a floating reference.
Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one.
Removes a weak reference from @object that was previously added using g_object_add_weak_pointer(). The @weak_pointer_location has to match the one used with g_object_add_weak_pointer().
Compares the user data for the key @key on @object with @oldval, and if they are the same, replaces @oldval with @newval.
Compares the user data for the key @quark on @object with @oldval, and if they are the same, replaces @oldval with @newval.
Releases all references to other objects. This can be used to break reference cycles.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed.
Sets a property on an object.
This sets an opaque, named pointer on an object. The name is specified through a #GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the @object with g_object_get_qdata() until the @object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using #NULL as pointer essentially removes the data stored.
This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with @data as argument when the @object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same @quark.
Sets properties on an object.
Sets @n_properties properties for an @object. Properties to be set will be taken from @values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
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: |[<!-- language="C" --> 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"); // retrive the old string list GList *list = g_object_steal_qdata (object, quark_string_list);
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.
Decreases the reference count of @object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).
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.
Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive).
Removes a weak reference callback to an object.
Clears a reference to a #GObject.
Lets you load SVG data and render it.
