pub struct Graphics<'buffer> { /* private fields */ }

Implementations

impl Graphics<'_>

pub fn index(&self, x: usize, y: usize) -> usize

Convert an x,y coord to idx for use with self.pixels

pub fn width(&self) -> usize

pub fn height(&self) -> usize

pub fn is_on_screen(&self, point: Coord) -> bool

impl Graphics<'_>

pub fn get_translate(&self) -> Coord

Get the canvas offset in pixels

pub fn set_translate(&mut self, new_value: Coord) -> Coord

Set the canvas offset in pixels

All drawing commands will be offset by this value

Returns

The previous translate value

pub fn with_translate<F>(&mut self, set: Coord, method: F)where F: Fn(&mut Graphics<'_>),

pub fn update_translate(&mut self, delta: Coord)

Adds delta to the current canvas offset

pub fn copy_to_image(&self) -> Image

Copy entire pixels array to an image

pub fn get_px_for_char(x: usize, y: usize, size: TextSize) -> (usize, usize)

Get top left pixel coord for letter px coord

pub fn get_text_size(text: &str, width: usize, size: TextSize) -> (usize, usize)

Get width and height for string

Arguments

• text - The string to be measured
• width - The line width in characters
• size - The text size to use when measuring

Returns

The width and height of the string in pixels

pub fn draw_image<P>(&mut self, xy: P, image: &Image)where P: Into<Coord>,

Draw an image at x, y

pub fn draw_indexed_image<P>(&mut self, xy: P, image: &IndexedImage)where P: Into<Coord>,

Draw an indexed image at x, y

pub fn draw_animated_image<P>(&mut self, xy: P, image: &AnimatedIndexedImage)where P: Into<Coord>,

Draw an animated image at x, y

pub fn draw_arc( &mut self, center: Coord, angle_start: isize, angle_end: isize, radius: usize, close: bool, color: Color )

pub fn draw_line<P1, P2>(&mut self, start: P1, end: P2, color: Color)where P1: Into<Coord>, P2: Into<Coord>,

pub fn draw_offset<T, P>(&mut self, xy: P, renderable: &dyn Renderable<T>)where P: Into<Coord>,

Draw renderable offset by [xy]

pub fn draw<T>(&mut self, renderable: &dyn Renderable<T>)

Draw renderable

pub fn update_pixel(&mut self, x: isize, y: isize, color: Color)

Update a pixel color, using set_pixel or blend_pixel depending on whether colors alpha is 255 or not If the alpha is 0 the call is does nothing

pub fn clear(&mut self, color: Color)

Sets every pixel to the same color, this ignores translate and clip

pub fn clear_aware(&mut self, color: Color)

Sets every pixel to the same color, same as [clear] but this follows translate and clip

pub fn draw_letter( &mut self, pos: (isize, isize), chr: char, size: TextSize, color: Color )

Draw a letter at pos

pub fn draw_ascii_letter( &mut self, pos: (isize, isize), code: u8, size: TextSize, color: Color )

pub fn draw_ascii<P, F>(&mut self, text: &[Vec<u8, Global>], pos: P, format: F)where P: Into<TextPos>, F: Into<TextFormat>,

Should only be used by Text::render text param must already be corrected wrapped

pub fn draw_text<P, F>(&mut self, text: &str, pos: P, format: F)where P: Into<TextPos>, F: Into<TextFormat>,

pub fn draw_rect<R>(&mut self, rect: R, draw_type: DrawType)where R: Into<Rect>,

pub fn draw_circle<C>(&mut self, circle: C, draw_type: DrawType)where C: Into<Circle>,

pub fn draw_polygon<P>(&mut self, polygon: P, draw_type: DrawType)where P: Into<Polygon>,

pub fn draw_triangle<T>(&mut self, triangle: T, draw_type: DrawType)where T: Into<Triangle>,

pub fn blend_pixel(&mut self, x: isize, y: isize, color: Color)

Set the RGB values for a pixel by blending it with the provided color This method uses alpha blending, note that the canvas pixels always have 255 alpha

pub fn set_pixel(&mut self, x: isize, y: isize, color: Color)

Set the RGB values for a pixel

Generally you should use update_pixel instead

This ignores alpha, so 255,0,0,0 will draw a red pixel
