Struct graphics::draw_state::DrawState

pub struct DrawState {
    pub scissor: Option<[u32; 4]>,
    pub stencil: Option<Stencil>,
    pub blend: Option<Blend>,
}

Graphics draw state used for blending, clipping and stencil rendering.

Fields

scissor	Scissor mask to use. If set, no pixel outside of this rectangle (in screen space) will be written to as a result of rendering.
stencil	Stencil test to use. If None, no stencil testing is done.
blend	Blend function to use. If None, blending is disabled.

Methods

impl DrawState

fn new_alpha() -> DrawState

Uses alpha blending.

fn new_clip() -> DrawState

Draws to stencil buffer with value 255. This can be used for clipping.

fn new_inside() -> DrawState

Tests against stencil buffer with value 255. Draws inside the shape defined by stencil buffer.

fn new_outside() -> DrawState

Tests against stencil buffer with value 255. Draws outside the shape defined by stencil buffer.

fn blend(self, blend: Blend) -> DrawState

Sets blending.

fn scissor(self, scissor: [u32; 4]) -> DrawState

Sets scissor [x, y, w, h].
