Struct wlroots::render::Renderer

pub struct Renderer<'output> {
    pub damage: Option<(PixmanRegion, Duration)>,
    pub output: &'output mut Output,
    // some fields omitted
}

The state machine type that allows you to manipulate a screen and its buffer.

When this structure is dropped it automatically calls wlr_renderer_end and swaps the buffers.

Fields

damage: Option<(PixmanRegion, Duration)>

output: &'output mut Output

Methods

impl<'output> Renderer<'output>

pub fn create_texture_from_pixels(     &mut self,     format: wl_shm_format,     stride: u32,     width: u32,     height: u32,     data: &[u8] ) -> Option<Texture<'static>>

Create a texture using this renderer.

pub fn clear(&mut self, float: [f32; 4])

pub fn render_texture(     &mut self,     texture: &Texture,     projection: [f32; 9],     x: c_int,     y: c_int,     alpha: c_float ) -> bool

Renders the requseted texture.

pub fn render_texture_with_matrix(     &mut self,     texture: &Texture,     matrix: [f32; 9] ) -> bool

Renders the requested texture using the provided matrix. A typical texture rendering goes like so:

TODO FIXME Show how the typical rendering goes in Rust.

struct wlr_renderer *renderer;
struct wlr_texture *texture;
float projection[16];
float matrix[16];
wlr_texture_get_matrix(texture, &matrix, &projection, 123, 321);
wlr_render_texture_with_matrix(renderer, texture, &matrix);

This will render the texture at <123, 321>.

pub fn render_scissor<T>(&mut self, area: T) where     T: Into<Option<Area>>,

Defines a scissor box. Only pixels that lie within the scissor box can be modified by drawing functions.

Providing a None for area disables the scissor box.

pub fn render_colored_quad(&mut self, color: [f32; 4], matrix: [f32; 9])

Renders a solid quad in the specified color.

pub fn render_colored_ellipse(&mut self, color: [f32; 4], matrix: [f32; 9])

Renders a solid ellipse in the specified color.

pub fn render_colored_rect(     &mut self,     area: Area,     color: [f32; 4],     matrix: [f32; 9] )

Renders a solid rectangle in the specified color.
