ApngDecoder

oximedia_codec::apng

Struct ApngDecoder

pub struct ApngDecoder;

Expand description

APNG decoder — parses an APNG byte stream and reconstructs ApngFrames.

Implementations§

impl ApngDecoder

pub fn decode(data: &[u8]) -> Result<(Vec<ApngFrame>, ApngConfig), CodecError>

Decode a raw APNG byte stream.

Returns the list of frames (with decompressed RGBA pixels) and the global ApngConfig.

§Errors

Returns CodecError if the PNG signature is missing, any chunk is truncated, or pixel decompression fails.

pub fn frame_count(data: &[u8]) -> Result<u32, CodecError>

Quick probe: returns the number of frames declared in the acTL chunk.

Does not decompress pixel data.

§Errors

Returns CodecError if the PNG signature is invalid or the file is truncated.

pub fn is_apng(data: &[u8]) -> bool

Returns true if data is an APNG (valid PNG signature + acTL chunk).
