Creates a new pixbuf loader object.
Informs a pixbuf loader that no further writes with gdkpixbuf.pixbuf_loader.PixbufLoader.write will occur, so that it can free its internal loading structures.
Connect to AreaPrepared signal.
Connect to AreaUpdated signal.
Connect to Closed signal.
Connect to SizePrepared signal.
Queries the #GdkPixbufAnimation that a pixbuf loader is currently creating.
Obtains the available information about the format of the currently loading image file.
Queries the #GdkPixbuf that a pixbuf loader is currently creating.
Causes the image to be scaled while it is loaded.
Parses the next count bytes in the given image buffer.
Parses the next contents of the given image buffer.
Creates a new pixbuf loader object that always attempts to parse image data as if it were an image of MIME type mime_type, instead of identifying the type automatically.
Creates a new pixbuf loader object that always attempts to parse image data as if it were an image of type image_type, instead of identifying the type automatically.
Set the GObject of a D ObjectG wrapper.
Get a pointer to the underlying C object.
Calls g_object_ref() on a GObject.
Calls g_object_unref() on a GObject.
Get the GType of an object.
GObject GType property.
Convenience method to return this cast to a type. For use in D with statements.
Template to get the D object from a C GObject and cast it to the given D object type.
Connect a D closure to an object signal.
Template for setting a GObject property.
Template for getting a GObject property.
Creates a binding between source_property on source and target_property on target.
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 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 gobject.object.ObjectG.refSink.
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 gobject.object.ObjectG.setData).
Gets a property of an object.
This function gets back user data pointers stored via gobject.object.ObjectG.setQdata.
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.
Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.
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.
Sets a property on an object.
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 gobject.object.ObjectG.setQdata 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:
Reverts the effect of a previous call to gobject.object.ObjectG.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.
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 gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectG.ref_ and gobject.object.ObjectG.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.
Connect to Notify signal.
Incremental image loader.
gdkpixbuf.pixbuf_loader.PixbufLoader provides a way for applications to drive the process of loading an image, by letting them send the image data directly to the loader instead of having the loader read the data from a file. Applications can use this functionality instead of [gdkpixbuf.pixbuf.Pixbuf.newFromFile] or [gdkpixbuf.pixbuf_animation.PixbufAnimation.newFromFile] when they need to parse image data in small chunks. For example, it should be used when reading an image from a (potentially) slow network connection, or when loading an extremely large file.
To use gdkpixbuf.pixbuf_loader.PixbufLoader to load an image, create a new instance, and call gdkpixbuf.pixbuf_loader.PixbufLoader.write to send the data to it. When done, gdkpixbuf.pixbuf_loader.PixbufLoader.close should be called to end the stream and finalize everything.
The loader will emit three important signals throughout the process:
Loading an animation
Loading an animation is almost as easy as loading an image. Once the first signal@GdkPixbuf.PixbufLoader::area-prepared signal has been emitted, you can call gdkpixbuf.pixbuf_loader.PixbufLoader.getAnimation to get the gdkpixbuf.pixbuf_animation.PixbufAnimation instance, and then call and gdkpixbuf.pixbuf_animation.PixbufAnimation.getIter to get a gdkpixbuf.pixbuf_animation_iter.PixbufAnimationIter to retrieve the pixbuf for the desired time stamp.
