Struct plotters_bitmap::bitmap_pixel::BGRXPixel

pub struct BGRXPixel;

The marker type that indicates we are currently using a BGRX8888 pixel format

Trait Implementations

impl PixelFormat for BGRXPixel

const PIXEL_SIZE: usize = 4usize

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 blend_rect_fast( target: &mut BitMapBackend<'_, Self>, upper_left: (i32, i32), bottom_right: (i32, i32), r: u8, g: u8, b: u8, a: f64, )

The fast alpha blending algorithm for this pixel format

fn fill_rect_fast( target: &mut BitMapBackend<'_, Self>, upper_left: (i32, i32), bottom_right: (i32, i32), r: u8, g: u8, b: u8, )

The fast rectangle filling algorithm

fn fill_vertical_line_fast( target: &mut BitMapBackend<'_, Self>, x: i32, ys: (i32, i32), r: u8, g: u8, b: u8, )

The fast vertical line filling algorithm

fn draw_pixel( target: &mut BitMapBackend<'_, Self>, point: (i32, i32), (r, g, b): (u8, u8, u8), alpha: f64, )

Drawing a single pixel in this format

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
