Struct PackedSpec 

pub struct PackedSpec {
    pub width: usize,
    pub height: usize,
    pub bits: u32,
    pub flags: u32,
    pub field2_offset: Option<usize>,
}

A load-flags packed raster description.

Fields

width: usize

height: usize

bits: u32

Bits per sample (1..=16).

flags: u32

Load flags (see the module docs).

field2_offset: Option<usize>

Byte offset (relative to the start of src) of the second field when flags & 4.
