Implementations§

source§

impl GLTexture

source

pub fn release(&self)

Releases the GL resources held by a GLTexture.

The texture contents are still available via the TextureExtManual::download() function, after this function has been called.

source§

impl GLTexture

source

pub unsafe fn new(context: &GLContext, id: u32, width: i32, height: i32) -> Self

Creates a new texture for an existing GL texture.

Note that the GL texture must not be modified until @destroy is called, which will happen when the GdkTexture object is finalized, or due to an explicit call of release().

context

a GLContext

id

the ID of a texture that was created with @context

width

the nominal width of the texture

height

the nominal height of the texture

Returns

A newly-created Texture

source

pub unsafe fn with_release_func<F: FnOnce() + 'static>( context: &GLContext, id: u32, width: i32, height: i32, release_func: F ) -> Self
