Struct gfx_gtk::PostprocessContext

pub struct PostprocessContext<D> where
    D: Device,  {
    pub sampler: Sampler<D::Resources>,
    pub pso: PipelineState<D::Resources, Meta>,
    pub vbuf: Buffer<D::Resources, BlitVertex>,
    pub ibuf: Slice<D::Resources>,
}

a container for the pre-built data and state needed to perform MSAA resolution and sRGB correction in the post-processing stage

Fields

sampler: Sampler<D::Resources>

a sampler for the source framebuffer

pso: PipelineState<D::Resources, Meta>

pipeline state object with rasterizer and blit shaders

vbuf: Buffer<D::Resources, BlitVertex>

a single large triangle (vertices) covering the full screen

ibuf: Slice<D::Resources>

a single large triangle (indices)

Methods

impl PostprocessContext<GlDevice>

pub fn full_screen_blit<CF>(     &self,     encoder: &mut Encoder<GlResources, GlCommandBuffer>,     render_screen: &GlFrameBufferTextureSrc<CF>,     post_target: &GlFrameBuffer<GtkTargetColorFormat> ) where     CF: Formatted<View = GtkTargetColorView>,     CF::Channel: TextureChannel + RenderChannel,     CF::Surface: RenderSurface + TextureSurface,

performs a full screen pass using the original render screen as the source and the GTK framebuffer as the target, using baked-in settings TODO: make this easy to override
