Struct Frame 

pub struct Frame {
    pub precision: u8,
    pub width: u16,
    pub height: u16,
    pub components: Vec<Component>,
}

A parsed start-of-frame header.

Fields

precision: u8

Sample precision in bits. Baseline is always 8.

width: u16

Image width in pixels.

height: u16

Image height in pixels. Zero here means the height is deferred to a DNL marker after the first scan.

components: Vec<Component>

The components, in the order the frame declares them.

Implementations

impl Frame

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

Parse a SOF0/SOF1 payload (the bytes after the segment length).

Errors

Returns PixelsError::Malformed for a truncated header, a zero width, an out-of-range sampling factor or a duplicate component id.

pub fn h_max(&self) -> u8

The largest horizontal sampling factor across components.

pub fn v_max(&self) -> u8

The largest vertical sampling factor across components.
