Texture
open class Texture : GLibObject.Object, TextureProtocol
The Texture
type acts as a reference-counted owner of an underlying GdkTexture
instance.
It provides the methods that can operate on this data type through TextureProtocol
conformance.
Use Texture
as a strong reference or owner of a GdkTexture
instance.
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
[methodGdk.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()
.
-
Designated initialiser from the underlying `C` data type.
This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the
Texture
instance.Declaration
Swift
@inlinable public init(_ op: UnsafeMutablePointer<GdkTexture>)
Parameters
op
pointer to the underlying object
-
Designated initialiser from a constant pointer to the underlying
C
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theTexture
instance.Declaration
Swift
@inlinable public init(_ op: UnsafePointer<GdkTexture>)
Parameters
op
pointer to the underlying object
-
Optional initialiser from a non-mutating
gpointer
to the underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theTexture
instance.Declaration
Swift
@inlinable override public init!(gpointer op: gpointer?)
Parameters
op
gpointer to the underlying object
-
Optional initialiser from a non-mutating
gconstpointer
to the underlyingC
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theTexture
instance.Declaration
Swift
@inlinable override public init!(gconstpointer op: gconstpointer?)
Parameters
op
pointer to the underlying object
-
Optional initialiser from a constant pointer to the underlying
C
data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theTexture
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafePointer<GdkTexture>?)
Parameters
op

data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to theTexture
instance.Declaration
Swift
@inlinable public init!(_ op: UnsafeMutablePointer<GdkTexture>?)
Parameters

data type. Will retainGdkTexture
. i.e., ownership is transferred to theTexture
instance.Declaration

TextureProtocol
.Declaration
Swift
@inlinable override public init(retainingOpaquePointer p: OpaquePointer)

-
Creates a new texture object representing the
GdkPixbuf
.Declaration
Swift
@inlinable public init<PixbufT>(pixbuf: PixbufT) where PixbufT : PixbufProtocol
-
Creates a new texture by loading an image from a file.
The file format is detected automatically. The supported formats are PNG and JPEG, though more formats might be available.
If
nil
is returned, thenerror
will be set.Declaration
Swift
@inlinable public init<FileT>(file: FileT) throws where FileT : FileProtocol
-
Creates a new texture by loading an image from a resource.
The file format is detected automatically. The supported formats are PNG and JPEG, though more formats might be available.
It is a fatal error if
resource_path
does not specify a valid image resource and the program will abort if that happens. If you are unsure about the validity of a resource, use [ctorGdk.Texture.new_from_file
] to load it.Declaration
Swift
@inlinable public init(resource resourcePath: UnsafePointer<CChar>!)
-

GdkPixbuf

@inlinable public static func newFor<PixbufT>(pixbuf: PixbufT) -> Texture! where PixbufT : PixbufProtocol
-
Creates a new texture by loading an image from a file.
