Implementations

impl Viewport

pub fn new(position: ScreenPos, size: ScreenSize) -> Self

Create a new viewport with a given screen position.

pub fn resize(&mut self, width: u16, height: u16)

Resize the viewport. Remember to clear the renderer or residual characters might remain.

pub fn draw_pixels(&mut self, pixels: Vec<Pixel>)

Draw the pixels onto the renderable surface layers. This is offset by the camera and the viewport.

pub fn draw_pixel(&mut self, pixel: Pixel)

Draw a single pixel onto the rendereable surface layers. This is called from draw_pixels for each pixel.

This is useful if it’s desired to draw just one pixel.

pub fn draw_widget(&mut self, widget: &impl Widget, offset: ScreenPos)

Draw a widget with an offset in the viewport.
