Struct CompositeBlendPipelines

pub struct CompositeBlendPipelines {
    pub pipeline: RenderPipeline,
    pub params_layout: BindGroupLayout,
    pub tex_layout: BindGroupLayout,
    pub sampler: Sampler,
}

Pipelines for compositing an isolated fg texture over a captured dst region.

Examples

use ailloli_ui_render_wgpu::composite_blend::CompositeBlendPipelines;
let _: usize = std::mem::size_of::<CompositeBlendPipelines>();

Fields

pipeline: RenderPipeline

Render pipeline implementing normal, multiply, and screen equations.

params_layout: BindGroupLayout

Uniform layout for shader mode and clamped opacity.

tex_layout: BindGroupLayout

Shared texture-plus-sampler layout for foreground and background.

sampler: Sampler

Linear sampler used for both captured textures.

Implementations

impl CompositeBlendPipelines

pub fn new(device: &Device, surface_format: TextureFormat) -> Self

Builds blend resources for one exact output format.

Examples

use ailloli_ui_render_wgpu::composite_blend::CompositeBlendPipelines;
fn build(device: &wgpu::Device) -> CompositeBlendPipelines {
    CompositeBlendPipelines::new(device, wgpu::TextureFormat::Bgra8UnormSrgb)
}
