pub struct Texture { /* private fields */ }

A container for a bindable texture.

Implementations

impl Texture

pub fn from_raw_parts(
    texture: Texture,
    view: TextureView,
    bind_group: BindGroup,
    size: Extent3d
) -> Self

Create a Texture from its raw parts.

pub fn new(
    device: &Device,
    renderer: &Renderer,
    config: TextureConfig<'_>
) -> Self

Create a new GPU texture width the specified config.

        // Clear imgui texture data to save memory.
        fonts.clear_tex_data();
    }

pub fn write(&self, queue: &Queue, data: &[u8], width: u32, height: u32)

Write data to the texture.

• data: 32-bit RGBA bitmap data.
• width: The width of the source bitmap (data) in pixels.
• height: The height of the source bitmap (data) in pixels.
