Struct SourcePresentation 

pub struct SourcePresentation {
    pub output_size: RenderSize,
    pub visible_rect: Rect,
    pub orientation: Orientation,
    pub sample_aspect_ratio: (u32, u32),
    pub chroma_siting: ChromaLocation,
}

GPU presentation transform applied while converting a decoded source.

Fields

output_size: RenderSize

Destination canvas. Pixels outside the contained source are transparent.

visible_rect: Rect

Visible crop inside the coded source.

orientation: Orientation

How the source is shown upright: mirrored, then rotated.

sample_aspect_ratio: (u32, u32)

Horizontal pixel aspect-ratio numerator and denominator.

chroma_siting: ChromaLocation

Chroma sample position. An unspecified location is sampled as centered.
