Struct gdk4::Texture

#[repr(transparent)]
pub struct Texture { /* private fields */ }

Texture 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 Texture objects from a gdk_pixbuf::Pixbuf, or from bytes stored in memory, a file, or a Gio::Resource.

The ownership of the pixel data is transferred to the Texture instance; you can only make a copy of it, via TextureExtManual::download().

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

This is an Abstract Base Class, you cannot instantiate it.

Implementations

impl Texture

pub const NONE: Option<&'static Texture> = None

pub fn for_pixbuf(pixbuf: &Pixbuf) -> Texture

Creates a new texture object representing the gdk_pixbuf::Pixbuf.

This function is threadsafe, so that you can e.g. use GTask and Gio::Task::run_in_thread() to avoid blocking the main thread while loading a big image.

pixbuf

a gdk_pixbuf::Pixbuf

Returns

a new Texture

pub fn from_bytes(bytes: &Bytes) -> Result<Texture, Error>

Available on crate feature v4_6 only.

Creates a new texture by loading an image from memory,

The file format is detected automatically. The supported formats are PNG, JPEG and TIFF, though more formats might be available.

If None is returned, then @error will be set.

This function is threadsafe, so that you can e.g. use GTask and Gio::Task::run_in_thread() to avoid blocking the main thread while loading a big image.

bytes

a GBytes containing the data to load

Returns

A newly-created Texture

pub fn from_file(file: &impl IsA<File>) -> Result<Texture, Error>

Creates a new texture by loading an image from a file.

The file format is detected automatically. The supported formats are PNG, JPEG and TIFF, though more formats might be available.

If None is returned, then @error will be set.

This function is threadsafe, so that you can e.g. use GTask and Gio::Task::run_in_thread() to avoid blocking the main thread while loading a big image.

file

GFile to load

Returns

A newly-created Texture

pub fn from_filename(path: impl AsRef<Path>) -> Result<Texture, Error>

Available on crate feature v4_6 only.

Creates a new texture by loading an image from a file.

The file format is detected automatically. The supported formats are PNG, JPEG and TIFF, though more formats might be available.

If None is returned, then @error will be set.

This function is threadsafe, so that you can e.g. use GTask and Gio::Task::run_in_thread() to avoid blocking the main thread while loading a big image.

path

the filename to load

Returns

A newly-created Texture

pub fn from_resource(resource_path: &str) -> Texture

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 from_file() to load it.

This function is threadsafe, so that you can e.g. use GTask and Gio::Task::run_in_thread() to avoid blocking the main thread while loading a big image.

resource_path

the path of the resource file

Returns

A newly-created Texture

Trait Implementations

impl Clone for Texture

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Texture

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Texture

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for Texture

type ParamSpec = ParamSpecObject

type SetValue = Texture

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, Texture>

fn param_spec_builder() -> Self::BuilderFn
