Struct Scan 

pub struct Scan {
    pub components: Vec<ScanComponent>,
    pub spectral_start: u8,
    pub spectral_end: u8,
    pub approx_high: u8,
    pub approx_low: u8,
}

A parsed start-of-scan header.

Fields

components: Vec<ScanComponent>

The components this scan codes, in the order they interleave.

spectral_start: u8

First coefficient in the spectral selection.

spectral_end: u8

Last coefficient in the spectral selection.

approx_high: u8

Successive approximation high bit.

approx_low: u8

Successive approximation low bit.

Implementations

impl Scan

pub fn parse(payload: &[u8], frame: &Frame) -> Result<Self>

Parse an SOS payload against the frame it belongs to.

Errors

Returns PixelsError::Malformed for a truncated header, a component id the frame never declared, or a table slot above 3.

Trait Implementations
