Struct JpegCodec 

pub struct JpegCodec;

JPEG codec marker type for j2k-core trait integrations.

Trait Implementations

impl Clone for JpegCodec

fn clone(&self) -> JpegCodec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for JpegCodec

impl Debug for JpegCodec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for JpegCodec

fn default() -> JpegCodec

Returns the “default value” for a type.

impl Eq for JpegCodec

impl ImageCodec for JpegCodec

type Error = JpegError

Codec-specific error type.

type Warning = Warning

Non-fatal warning type returned in successful decode outcomes.

type Pool = ScratchPool

Caller-owned scratch pool type used to reuse allocations.

impl PartialEq for JpegCodec

fn eq(&self, other: &JpegCodec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for JpegCodec

impl TileBatchDecode for JpegCodec

type Context = DecoderContext

Codec-specific context cached across tiles.

fn decode_tile( ctx: &mut CoreDecoderContext<Self::Context>, pool: &mut Self::Pool, input: &[u8], out: &mut [u8], stride: usize, fmt: PixelFormat, ) -> Result<CoreDecodeOutcome<Self::Warning>, Self::Error>

Decode one tile into caller-owned output.

fn decode_tile_region( ctx: &mut CoreDecoderContext<Self::Context>, pool: &mut Self::Pool, input: &[u8], out: &mut [u8], stride: usize, fmt: PixelFormat, roi: Rect, ) -> Result<CoreDecodeOutcome<Self::Warning>, Self::Error>

Decode one tile region into caller-owned output.

fn decode_tile_scaled( ctx: &mut CoreDecoderContext<Self::Context>, pool: &mut Self::Pool, input: &[u8], out: &mut [u8], stride: usize, fmt: PixelFormat, scale: Downscale, ) -> Result<CoreDecodeOutcome<Self::Warning>, Self::Error>

Decode one tile at reduced resolution into caller-owned output.

fn decode_tile_region_scaled( ctx: &mut CoreDecoderContext<Self::Context>, pool: &mut Self::Pool, input: &[u8], out: &mut [u8], stride: usize, fmt: PixelFormat, roi: Rect, scale: Downscale, ) -> Result<CoreDecodeOutcome<Self::Warning>, Self::Error>

Decode one tile region at reduced resolution into caller-owned output.

fn decode_tile_request<'a>( ctx: &mut DecoderContext<Self::Context>, pool: &mut Self::Pool, input: &'a [u8], out: &mut [u8], stride: usize, fmt: PixelFormat, request: DecodeRequest, ) -> Result<DecodeOutcome<Self::Warning>, Self::Error>

Decode one tile for a normalized full/ROI/scaled request.
