Struct DrawBeginClip 

#[repr(C)]
pub struct DrawBeginClip {
    pub blend_mode: u32,
    pub alpha: f32,
}

Draw data for a clip or layer.

Fields

blend_mode: u32

Blend mode.

alpha: f32

Group alpha.

Implementations

impl DrawBeginClip

pub const LUMINANCE_MASK_BLEND_MODE: u32 = 0x10000

The blend_mode used to indicate that a layer should be treated as a luminance mask.

The least significant 16 bits are reserved for Mix + Compose combinations.

pub const CLIP_BLEND_MODE: u32 = 0x8003

The blend_mode used to indicate that a layer should be treated as a clip.

This is equivalent to Compose::SrcOver with a Mix of 128, for legacy reasons. We expect this to change in the future.

pub fn new(blend_mode: BlendMode, alpha: f32) -> Self

Creates new clip draw data for a Porter-Duff blend mode.

pub fn luminance_mask(alpha: f32) -> Self

Creates a new clip draw data for a luminance mask.

pub fn clip() -> Self

Creates the clip draw data for a clip-only layer.
