Struct RendererPrimitives 

pub struct RendererPrimitives<'a, PF: PixelFormat> { /* private fields */ }

Basic shape primitives renderer.

Draws rectangles, ellipses, and Bresenham lines directly into a RendererBase without anti-aliasing. Maintains separate fill and line colors and a current position for line_to operations.

Port of C++ renderer_primitives<BaseRenderer>.

Implementations

impl<'a, PF: PixelFormat> RendererPrimitives<'a, PF>

where PF::ColorType: Default + Clone,

pub fn new(ren: &'a mut RendererBase<PF>) -> Self

pub fn coord(c: f64) -> i32

Convert a floating-point coordinate to subpixel Bresenham coordinate.

pub fn set_fill_color(&mut self, c: PF::ColorType)

pub fn set_line_color(&mut self, c: PF::ColorType)

pub fn fill_color(&self) -> &PF::ColorType

pub fn line_color(&self) -> &PF::ColorType

pub fn rectangle(&mut self, x1: i32, y1: i32, x2: i32, y2: i32)

Draw an outlined rectangle (line color only).

pub fn solid_rectangle(&mut self, x1: i32, y1: i32, x2: i32, y2: i32)

Draw a solid filled rectangle (fill color only).

pub fn outlined_rectangle(&mut self, x1: i32, y1: i32, x2: i32, y2: i32)

Draw an outlined and filled rectangle.

pub fn ellipse(&mut self, x: i32, y: i32, rx: i32, ry: i32)

Draw an outlined ellipse (line color only).

pub fn solid_ellipse(&mut self, x: i32, y: i32, rx: i32, ry: i32)

Draw a solid filled ellipse (fill color only).

pub fn outlined_ellipse(&mut self, x: i32, y: i32, rx: i32, ry: i32)

Draw an outlined and filled ellipse.

pub fn line(&mut self, x1: i32, y1: i32, x2: i32, y2: i32, last: bool)

Draw a Bresenham line from (x1,y1) to (x2,y2).

Coordinates are in subpixel units (use coord() to convert).

pub fn move_to(&mut self, x: i32, y: i32)

Set the current position for line_to.

pub fn line_to(&mut self, x: i32, y: i32, last: bool)

Draw a line from the current position to (x, y).

pub fn ren(&self) -> &RendererBase<PF>

pub fn ren_mut(&mut self) -> &mut RendererBase<PF>
