Struct forma::buffer::layout::LinearLayout

pub struct LinearLayout { /* private fields */ }

A linear buffer layout where each optionally strided pixel row of an image is saved sequentially into the buffer.

Implementations

impl LinearLayout

pub fn new(width: usize, width_stride: usize, height: usize) -> LinearLayout

Creates a new linear layout from width, width_stride (in bytes) and height.

Examples

let layout = LinearLayout::new(2, 3 * 4, 4);

assert_eq!(layout.width(), 2);

Trait Implementations

impl Debug for LinearLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Layout for LinearLayout

fn width(&self) -> usize

Width in pixels.

fn height(&self) -> usize

Height in pixels.

fn slices_per_tile(&self) -> usize

Number of buffer sub-slices that will be passes to Layout::write.

fn slices<'l, 'b>( &'l mut self, buffer: &'b mut [u8] ) -> Ref<'l, [Slice<'b, u8>]>

Returns self-stored sub-slices of buffer which are stored in a SliceCache.

fn write( slices: &mut [Slice<'_, u8>], flusher: Option<&dyn Flusher>, fill: TileFill<'_> )

Writes fill to slices, optionally calling the flusher.

fn width_in_tiles(&self) -> usize

Width in tiles.

fn height_in_tiles(&self) -> usize

Height in tiles.
