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().
Constructors
gdk_texture_new_for_pixbuf
Creates a new texture object representing the GdkPixbuf
.
gdk_texture_new_from_file
Creates a new texture by loading an image from a file.
gdk_texture_new_from_resource
Creates a new texture by loading an image from a resource.
Instance methods
gdk_texture_download
Downloads the texture
into local memory.
gdk_texture_get_height
Returns the height of the texture
, in pixels.
gdk_texture_get_width
Returns the width of texture
, in pixels.
gdk_texture_save_to_png
Store the given texture
to the filename
as a PNG file.

Signals
Signals inherited from GObject (1)
GObject.Object::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)
Gdk.Paintable::invalidate-contents
Emitted when the contents of the paintable
change.
Gdk.Paintable::invalidate-size
Emitted when the intrinsic size of the paintable
changes.
