OneBitFrame

Struct OneBitFrame 

Source
pub struct OneBitFrame { /* private fields */ }
Expand description

A one-bit picture of the display, 400 × 240, in the Playdate’s layout: each row ROW_BYTES bytes (padded to a whole number of 32-bit words, as its display takes them), a byte’s highest bit its left pixel, a set bit white.

Implementations§

Source§

impl OneBitFrame

Source

pub fn white() -> Self

The display, all white.

Source

pub const fn width(&self) -> i32

Its width in pixels.

Source

pub const fn height(&self) -> i32

Its height in pixels.

Source

pub fn bytes(&self) -> &Frame

Its bytes, row after row.

Source

pub fn bytes_mut(&mut self) -> &mut Frame

Its bytes, to draw in.

Source

pub fn is_white(&self, x: i32, y: i32) -> bool

Whether pixel (x, y) is white; off the display, false.

Source

pub fn changed_rows(&self, previous: &Self) -> RowMask

The rows it differs from previous in.
