Enum ScreenPixelFormat

#[repr(usize)]
pub enum ScreenPixelFormat {
    Mono = 0,
    Mono_8BitPage = 6,
    RGB_4BIT = 5,

How pixels are encoded for the screen.

Variants

Mono = 0

Pixels encoded as 1-bit, used for monochromatic displays.

Mono_8BitPage = 6

Pixels encoded as 1-bit, used for monochromatic displays.

The pixel order uses 8-bit (1-byte) pages where each page is displayed vertically. That is, buffer[0] bit0 is pixel (0,0), but buffer[0] bit1 is pixel (0,1). The page continues, so buffer[0] bit 7 is pixel (0,7). Then the page advances horizontally, so buffer[1] bit0 is pixel (1,0), and buffer[1] bit4 is pixel (1,4).

An example of a screen driver that uses this format is the SSD1306.

RGB_4BIT = 5

Pixels encoded as 1-bit blue, 1-bit green, 1-bit red, and 1-bit for opaque (1) vs transparent (0)

RGB_332 = 1

Pixels encoded as 3-bit red channel, 3-bit green channel, 2-bit blue channel.

RGB_565 = 2

Pixels encoded as 5-bit red channel, 6-bit green channel, 5-bit blue channel.

RGB_888 = 3

Pixels encoded as 8-bit red channel, 8-bit green channel, 8-bit blue channel.

ARGB_8888 = 4

Pixels encoded as 8-bit alpha channel, 8-bit red channel, 8-bit green channel, 8-bit blue channel.

Implementations

impl ScreenPixelFormat

pub fn get_bits_per_pixel(&self) -> usize

Trait Implementations

impl Clone for ScreenPixelFormat

fn clone(&self) -> ScreenPixelFormat

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for ScreenPixelFormat

fn eq(&self, other: &ScreenPixelFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
