Expand description

Tile-batch helpers that return synchronous device surfaces.

Required Associated Types§

Source

type Context: CodecContext

Codec-specific context cached across tiles.

Source

type DeviceSurface: DeviceSurface

Device surface returned by decode calls.

Provided Methods§

Source

fn decode_tile_to_device<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], fmt: PixelFormat, backend: BackendRequest, ) -> Result<Self::DeviceSurface, Self::Error>
where Self: TileBatchDecodeSubmit<Context = Self::Context, DeviceSurface = Self::DeviceSurface>,

Decode one tile to the requested backend.

Source

fn decode_tile_region_to_device<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], fmt: PixelFormat, roi: Rect, backend: BackendRequest, ) -> Result<Self::DeviceSurface, Self::Error>
where Self: TileBatchDecodeSubmit<Context = Self::Context, DeviceSurface = Self::DeviceSurface>,

Decode one tile region to the requested backend.

Source

fn decode_tile_scaled_to_device<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], fmt: PixelFormat, scale: Downscale, backend: BackendRequest, ) -> Result<Self::DeviceSurface, Self::Error>
where Self: TileBatchDecodeSubmit<Context = Self::Context, DeviceSurface = Self::DeviceSurface>,

Decode one tile at reduced resolution to the requested backend.

Source

fn decode_tile_region_scaled_to_device<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], fmt: PixelFormat, roi: Rect, scale: Downscale, backend: BackendRequest, ) -> Result<Self::DeviceSurface, Self::Error>
where Self: TileBatchDecodeSubmit<Context = Self::Context, DeviceSurface = Self::DeviceSurface>,

Decode one tile region at reduced resolution to the requested backend.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
