Struct plotters::element::BitMapElement

[+] Show declaration

pub struct BitMapElement<'a, Coord, P: PixelFormat = RGBPixel> { /* fields omitted */ }

[−] Expand description

The element that contains a bitmap on it

Methods

impl<'a, Coord, P: PixelFormat> BitMapElement<'a, Coord, P>[−]

pub fn new(pos: Coord, size: (u32, u32)) -> Self[−]

Create a new empty bitmap element. This can be use as the draw and blit pattern.

• pos: The left upper coordinate for the element
• size: The size of the bitmap

pub fn copy_to<Coord2>(&self, pos: Coord2) -> BitMapElement<Coord2, P>[−]

Copy the existing bitmap element to another location

• pos: The new location to copy

pub fn move_to(&mut self, pos: Coord)[−]

Move the existing bitmap element to a new position

• pos: The new position

pub fn as_bitmap_backend(&mut self) -> BitMapBackend<P>[−]

Make the bitmap element as a bitmap backend, so that we can use plotters drawing functionality on the bitmap element

fn draw<I: Iterator<Item = BackendCoord>>(
    &self,
    points: I,
    backend: &mut DB,
    _: (u32, u32)
) -> Result<(), DrawingErrorKind<DB::ErrorType>>[−]

Actually draws the element. The key points is already translated into the image coordinate and can be used by DC directly
