Struct Viewport

Source

pub struct Viewport {
    pub start: Complex,
    pub dx: Complex,
    pub dy: Complex,
}

Expand description

Maps physical pixel coordinates (x, y) to complex plane coordinates via an affine transform defined by start, dx (step per pixel in x) and dy (step per pixel in y).

Fields§

§start: Complex

Complex coordinate at pixel (0, 0).

§dx: Complex

Complex step per pixel along the screen X-axis.

§dy: Complex

Complex step per pixel along the screen Y-axis.

Implementations§

Source §

impl Viewport

Source

pub fn new(width: f64, height: f64, specs: &ViewportSpecs) -> Self

Constructs a viewport from physical screen size and rendering specs.

Source

pub fn map(&self, x: f64, y: f64) -> Complex

Maps physical pixel coordinate (x, y) to the corresponding complex value.
