PDF image specification - byte data and attributes that describe how image is encoded.

Fields

data: &'a [u8]

Image data - length is width * height * (bits_per_component/8) * 3 (for RGB).

width: Px

Width

height: Px

Height

bits_per_component: u8

Bits per component, usually 8

color_space: &'a [u8]

Color space, such as b“/DeviceGray“, b“/DeviceRGB“, b“/DeviceCMYK“

other: &'a [u8]

Any other attributes, e.g. b“/Filter/DCT“ for a jpeg
