Texture

Object Hierarchy:

Description:

[ CCode ( type_id = "gdk_texture_get_type ()" ) ]
public abstract class Texture : Object, Paintable, Icon, LoadableIcon

`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 [class@GdkPixbuf.Pixbuf], or from bytes stored in memory, a file, or a [ struct@Gio.Resource].

The ownership of the pixel data is transferred to the `GdkTexture` instance; you can only make a copy of it, via [method@Gdk.Texture.download].

`GdkTexture` is an immutable object: That means you cannot change anything about it other than increasing the reference count via [ method@GObject.Object.ref], and consequently, it is a thread-safe object.

Properties:

public int height { get; construct; }
The height of the texture, in pixels.
public int width { get; construct; }

Static methods:

public static Texture for_pixbuf (Pixbuf pixbuf)
Creates a new texture object representing the `GdkPixbuf`.
public static Texture from_bytes (Bytes bytes) throws Error
Creates a new texture by loading an image from memory,
public static Texture from_file (File file) throws Error
Creates a new texture by loading an image from a file.
public static Texture from_filename (string path) throws Error
Creates a new texture by loading an image from a file.
public static Texture from_resource (string resource_path)
Creates a new texture by loading an image from a resource.

Creation methods:
