Struct GlesTexture

pub struct GlesTexture(/* private fields */);

Available on crate feature renderer_gl only.

A handle to a GLES texture

The texture can be used with the same GlesRenderer it was created with, or one using a shared EGLContext.

Implementations

impl GlesTexture

pub unsafe fn from_raw( renderer: &GlesRenderer, internal_format: Option<GLenum>, opaque: bool, tex: GLuint, size: Size<i32, BufferCoord>, ) -> GlesTexture

Create a GlesTexture from a raw gl texture id.

It is expected to not be external or y_inverted.

Ownership over the texture is taken by the renderer, you should not free the texture yourself.

Safety

The renderer cannot make sure tex is a valid texture id.

pub fn tex_id(&self) -> GLuint

OpenGL texture id of this texture

This id will become invalid, when the GlesTexture is dropped and does not transfer ownership.

pub fn is_y_inverted(&self) -> bool

Whether the texture is upside down

pub fn is_unique_reference(&mut self) -> bool

Whether this is the only reference to this texture (strong or weak)

Note that this tracks only references to this Smithay object (that you can get by cloning it). If you make a reference via OpenGL directly somehow, you need to keep track of it on your own.
