Class

GdkTexture

Description [src]

abstract class Gdk.Texture : GObject.Object {
  /* No available fields */
}

GdkTexture is the basic element used to refer to pixel data.

It is primarily meant for pixel data that will not change over multiple frames, and will be used for a long time.

There are various ways to create GdkTexture objects from a GdkPixbuf, or a Cairo surface, or other pixel data.

The ownership of the pixel data is transferred to the GdkTexture instance; you can only make a copy of it, via gdk_texture_download().

GdkTexture is an immutable object: That means you cannot change anything about it other than increasing the reference count via g_object_ref(), and consequently, it is a thread-safe object.

gdk_texture_save_to_png

Store the given texture to the filename as a PNG file.

gdk_texture_save_to_png_bytes

Store the given texture in memory as a PNG file.

since: 4.6

Methods inherited from GObject (43)

Please see GObject for a full list of methods.

Methods inherited from GdkPaintable (9)
gdk_paintable_compute_concrete_size

Compute a concrete size for the GdkPaintable.

gdk_paintable_get_current_image

Gets an immutable paintable for the current contents displayed by paintable.

gdk_paintable_get_flags

Get flags for the paintable.

gdk_paintable_get_intrinsic_aspect_ratio

Gets the preferred aspect ratio the paintable would like to be displayed at.

gdk_paintable_get_intrinsic_height

Gets the preferred height the paintable would like to be displayed at.

gdk_paintable_get_intrinsic_width

Gets the preferred width the paintable would like to be displayed at.

gdk_paintable_invalidate_contents

Called by implementations of GdkPaintable to invalidate their contents.

gdk_paintable_invalidate_size

Called by implementations of GdkPaintable to invalidate their size.

gdk_paintable_snapshot

Snapshots the given paintable with the given width and height.

Methods inherited from GIcon (3)
g_icon_equal

Checks if two icons are equal.

g_icon_serialize

Serializes a GIcon into a GVariant. An equivalent GIcon can be retrieved back by calling g_icon_deserialize() on the returned value. As serialization will avoid using raw icon data when possible, it only makes sense to transfer the GVariant between processes on the same machine, (as opposed to over the network), and within the same file system namespace.

since: 2.38

g_icon_to_string

Generates a textual representation of icon that can be used for serialization such as when passing icon to a different process or saving it to persistent storage. Use g_icon_new_for_string() to get icon back from the returned string.

since: 2.20

Methods inherited from GLoadableIcon (3)
g_loadable_icon_load

Loads a loadable icon. For the asynchronous version of this function, see g_loadable_icon_load_async().

g_loadable_icon_load_async

Loads an icon asynchronously. To finish this function, see g_loadable_icon_load_finish(). For the synchronous, blocking version of this function, see g_loadable_icon_load().

g_loadable_icon_load_finish

Finishes an asynchronous icon load started in g_loadable_icon_load_async().

Properties

Gdk.Texture:height

The height of the texture, in pixels.

Gdk.Texture:width

The width of the texture, in pixels.

Signals

Signals inherited from GObject (1)
GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Signals inherited from GdkPaintable (2)
GdkPaintable::invalidate-contents

Emitted when the contents of the paintable change.

GdkPaintable::invalidate-size

Emitted when the intrinsic size of the paintable changes.
