Struct jumpy::prelude::egui::epaint::TextureHandle
pub struct TextureHandle {
tex_mngr: Arc<RwLock<TextureManager>>,
id: TextureId,
}
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§
§impl TextureHandle
impl TextureHandle
pub 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
pub fn set(&mut self, image: impl Into<ImageData>, options: TextureOptions)
pub fn set(&mut self, image: impl Into<ImageData>, options: TextureOptions)
Assign a new image to an existing texture.
pub fn set_partial(
&mut self,
pos: [usize; 2],
image: impl Into<ImageData>,
options: TextureOptions,
)
pub fn set_partial( &mut self, pos: [usize; 2], image: impl Into<ImageData>, options: TextureOptions, )
Assign a new image to a subregion of the whole texture.
