Struct zng_view::extensions::ExternalImages
source · pub struct ExternalImages { /* private fields */ }
Expand description
Tracks extension external images for a renderer.
Implementations§
source§impl ExternalImages
impl ExternalImages
sourcepub fn register_texture(
&mut self,
uv: TexelRect,
texture: GLuint,
) -> ExternalImageId
pub fn register_texture( &mut self, uv: TexelRect, texture: GLuint, ) -> ExternalImageId
Register an OpenGL texture.
Returns an ExternalImageId
that can be used in display lists.
The id is only valid in the same renderer, and the texture
must be generated by the same
GL API used by the renderer. Note that you must manage the texture
lifetime, unregister
only releases the external image entry.
sourcepub fn register_image(
&mut self,
descriptor: ImageDescriptor,
pixels: IpcBytes,
) -> ExternalImageId
pub fn register_image( &mut self, descriptor: ImageDescriptor, pixels: IpcBytes, ) -> ExternalImageId
Register a loaded image.
Returns an ExternalImageId
that can be used in display lists.
The pixels
are held in memory until unregister
or the window is closed.
sourcepub fn unregister(&mut self, id: ExternalImageId)
pub fn unregister(&mut self, id: ExternalImageId)
Unregister the image or texture.
The id
is invalid after this call, using it in a display list is undefined behavior and
will likely cause access violation or other memory problems.
