Struct piston_window::DrawState [−][src]
pub struct DrawState {
pub scissor: Option<[u32; 4]>,
pub stencil: Option<Stencil>,
pub blend: Option<Blend>,
}
Expand description
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
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
.
Increases stencil buffer. This can be used for nested clipping.
Tests against stencil buffer with value 255. Draws inside the shape defined by stencil buffer.
Tests against stencil buffer with value 255. Draws outside the shape defined by stencil buffer.
