Struct LcdBitmap 

pub struct LcdBitmap {
    pub width: u32,
    pub height: u32,
    pub rgb: Vec<u8>,
}

An LCD subpixel bitmap.

Stores three bytes per pixel (R, G, B) corresponding to the physical sub-pixel layout of an LCD screen. LCD rendering allows individual sub-pixel addressing for smoother horizontal antialiasing at small sizes on colour displays.

The buffer length must equal width * height * 3.

Fields

width: u32

Width in pixels (each pixel contains 3 sub-pixel bytes).

height: u32

Height in pixels.

rgb: Vec<u8>

Sub-pixel data in RGB order: width * height * 3 bytes.

Implementations

impl LcdBitmap

pub fn new(width: u32, height: u32, rgb: Vec<u8>) -> Self

Constructs a new LcdBitmap from its components.

Panics (debug only)

In debug builds a debug assertion fires if rgb.len() does not equal width * height * 3, catching accidental buffer-size mismatches early.

pub fn is_empty(&self) -> bool

Returns true if the bitmap has zero area.

Trait Implementations

fn clone(&self) -> LcdBitmap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LcdBitmap

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