Struct egui::TextureHandle
source · [−]pub struct TextureHandle { /* private fields */ }
Expand description
Used to paint images.
An image is pixels stored in RAM, and represented using ImageData
.
Before you can paint it however, you need to convert it to a texture.
If you are using egui, use egui::Context::load_texture
.
The TextureHandle
can be cloned cheaply.
When the last TextureHandle
for specific texture is dropped, the texture is freed.
See also TextureManager
.
Implementations
sourceimpl TextureHandle
impl TextureHandle
sourcepub fn new(
tex_mngr: Arc<RwLock<TextureManager>>,
id: TextureId
) -> TextureHandle
pub fn new(
tex_mngr: Arc<RwLock<TextureManager>>,
id: TextureId
) -> TextureHandle
If you are using egui, use egui::Context::load_texture
instead.
pub fn id(&self) -> TextureId
sourcepub fn set_partial(&mut self, pos: [usize; 2], image: impl Into<ImageData>)
pub fn set_partial(&mut self, pos: [usize; 2], image: impl Into<ImageData>)
Assign a new image to a subregion of the whole texture.
sourcepub fn aspect_ratio(&self) -> f32
pub fn aspect_ratio(&self) -> f32
width / height
