Struct plotters::backend::RGBPixel

pub struct RGBPixel;

The marker type that indicates we are currently using a RGB888 pixel format

Trait Implementations

impl PixelFormat for RGBPixel

const PIXEL_SIZE: usize = 3usize

Number of bytes per pixel

const EFFECTIVE_PIXEL_SIZE: usize = 3usize

Number of effective bytes per pixel, e.g. for BGRX pixel format, the size of pixel is 4 but the effective size is 3, since the 4th byte isn’t used

fn byte_at(r: u8, g: u8, b: u8, _a: u64, idx: usize) -> u8

Encoding a pixel and returns the idx-th byte for the pixel

fn decode_pixel(data: &[u8]) -> (u8, u8, u8, u64)

Decode a pixel at the given location

fn can_be_saved() -> bool

Indicates if this pixel format can be saved as image. Note: Currently we only using RGB pixel format in the image crate, but later we may lift this restriction
