Struct BlendLayer 

pub struct BlendLayer<'a> {
    pub data: &'a [u8],
    pub width: u32,
    pub height: u32,
    pub opacity: f32,
    pub blend_mode: BlendMode,
}

A single compositing layer.

The pixel data must be RGBA (4 bytes per pixel), packed row-major.

Fields

data: &'a [u8]

Raw RGBA pixel data.

width: u32

Layer width in pixels.

height: u32

Layer height in pixels.

opacity: f32

Global opacity in [0.0, 1.0] (multiplied into the alpha channel).

blend_mode: BlendMode

Blend mode applied when compositing this layer onto the accumulator.

Implementations

impl<'a> BlendLayer<'a>

pub fn new( data: &'a [u8], width: u32, height: u32, opacity: f32, blend_mode: BlendMode, ) -> Result<Self>

Create a new layer with the given parameters.

Errors

Returns an error if opacity is outside [0.0, 1.0] or if the buffer is too small for the given dimensions.

Trait Implementations

impl<'a> Clone for BlendLayer<'a>

fn clone(&self) -> BlendLayer<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for BlendLayer<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
