Struct JpegInfo 

pub struct JpegInfo {
    pub width: u16,
    pub height: u16,
    pub components: Vec<ComponentInfo>,
}

Image metadata extracted from a JPEG without decoding the entropy stream.

Obtained from inspect. Cheaper than read_coefficients when you only need dimensions, component count, or block counts.

Fields

width: u16

Image width in pixels.

height: u16

Image height in pixels.

components: Vec<ComponentInfo>

Per-component metadata, in SOF order (typically Y, Cb, Cr).
