Struct DecodeRequest 

pub struct DecodeRequest {
    pub fmt: PixelFormat,
    pub region: Option<Rect>,
    pub scale: Downscale,
}

Owned-output JPEG decode request.

This consolidates the full-image, region, and downscale axes for callers that want a freshly allocated tightly packed output buffer.

Fields

fmt: PixelFormat

Requested output pixel format.

region: Option<Rect>

Optional source-image region to decode.

scale: Downscale

Requested decoder downscale.

Implementations

impl DecodeRequest

pub const fn full(fmt: PixelFormat) -> Self

Full-image decode at native scale.

pub const fn scaled(fmt: PixelFormat, scale: Downscale) -> Self

Full-image decode with downscale.

pub const fn region(fmt: PixelFormat, region: Rect) -> Self

Region decode at native scale.

pub const fn region_scaled( fmt: PixelFormat, region: Rect, scale: Downscale, ) -> Self

Region decode with downscale.
