pub struct Texture { /* private fields */ }
Expand description
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.
§Properties
§height
The height of the texture, in pixels.
Readable | Writeable | Construct Only
§width
The width of the texture, in pixels.

Implementations§
Source§impl Texture
impl Texture
pub const NONE: Option<&'static Texture> = None
Sourcepub fn for_pixbuf(pixbuf: &Pixbuf) -> Texture
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
§Returns
a new Texture
Sourcepub fn from_bytes(bytes: &Bytes) -> Result<Texture, Error>
Available on crate feature v4_6
only.
pub fn from_bytes(bytes: &Bytes) -> Result<Texture, Error>
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
Sourcepub fn from_file(file: &impl IsA<File>) -> Result<Texture, Error>
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
Sourcepub fn from_filename(path: impl AsRef<Path>) -> Result<Texture, Error>
Available on crate feature v4_6
only.
pub fn from_filename(path: impl AsRef<Path>) -> Result<Texture, Error>
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
Sourcepub fn from_resource(resource_path: &str) -> 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
