Enum Layout 

pub enum Layout {
    Strips {
        rows_per_strip: u32,
    },
    Tiles {
        width: u32,
        height: u32,
    },
}

Whether the pixels are stored in strips or tiles.

Variants

Strips

Horizontal bands the full width of the image.

Fields

rows_per_strip: u32

Rows in each strip but the last.

Tiles

A grid of independently compressed rectangles.

This is the layout that makes region random access possible, and therefore the one M5’s exit criterion turns on.

Fields

width: u32

Tile width in pixels; always a multiple of 16.

height: u32

Tile height in pixels; always a multiple of 16.

Implementations

impl Layout

pub const fn is_random_access(self) -> bool
