Trait Implementations

impl Debug for Gles2Frame

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Frame for Gles2Frame

type Error = Gles2Error

Error type returned by the rendering operations of this renderer.

type TextureId = Gles2Texture

Texture Handle type used by this renderer.

fn clear(&mut self, color: [f32; 4]) -> Result<(), Self::Error>

Clear the complete current target with a single given color.

fn render_texture(
    &mut self,
    tex: &Self::TextureId,
    matrix: Matrix3<f32>,
    tex_coords: [Vector2<f32>; 4],
    alpha: f32
) -> Result<(), Self::Error>

Render a texture to the current target using given projection matrix and alpha. The given vertices are used to source the texture. This is mostly useful for cropping the texture.

fn render_texture_at(
    &mut self,
    texture: &Self::TextureId,
    pos: Point<f64, Physical>,
    texture_scale: i32,
    output_scale: f64,
    transform: Transform,
    alpha: f32
) -> Result<(), Self::Error>

Render a texture to the current target as a flat 2d-plane at a given position and applying the given transformation with the given alpha value.

fn render_texture_from_to(
    &mut self,
    texture: &Self::TextureId,
    src: Rectangle<i32, Buffer>,
    dest: Rectangle<f64, Physical>,
    transform: Transform,
    alpha: f32
) -> Result<(), Self::Error>

Render part of a texture as given by src to the current target into the rectangle described by dest as a flat 2d-plane after applying the given transformations.
