Expand description

A category of JPEG marker. Carried in JpegError::UnexpectedMarker and related variants so callers can branch on marker class without parsing the raw byte.

Variants§

§

Soi

Start of image (FFD8).

§

Sof

Start of frame (any of FFC0..=FFC3).

§

Dqt

Define quantization table (FFDB).

§

Dht

Define Huffman table (FFC4).

§

Dri

Define restart interval (FFDD).

§

Sos

Start of scan (FFDA).

§

Eoi

End of image (FFD9).

§

App14

Adobe APP14 (FFEE).

§

Other(u8)

Any other marker, raw byte preserved.
