Struct graphics::draw_state::DrawState[][src]

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: Option<[u32; 4]>

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: Option<Stencil>

Stencil test to use. If None, no stencil testing is done.

blend: Option<Blend>

Blend function to use. If None, blending is disabled.

Implementations

impl DrawState[src]

pub fn new_alpha() -> DrawState[src]

Uses alpha blending.

pub fn new_clip() -> DrawState[src]

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

For nested clipping, clear the stencil buffer and use DrawState::new_increment.

pub fn new_increment() -> DrawState[src]

Increases stencil buffer. This can be used for nested clipping.

pub fn new_inside() -> DrawState[src]

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

pub fn new_outside() -> DrawState[src]

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

pub fn blend(self, blend: Blend) -> DrawState[src]

Sets blending.

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

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