Struct orthoproj::OrthoProj

pub struct OrthoProj<T: Clone> { /* fields omitted */ }

An orthographic image

Images are square, with the globe in the middle. Create one with a size of 500x500, where all pixels are set to 0, centred on Rome:

# Examples

use orthoproj::OrthoProj;
let mut image = OrthoProj::new(500, 41.89889, 12.47337, 0);

We can then set pixels on this image, based on their lat/lon

image.set(51.50791, -0.12786, 1);

You can then loop over all the pixels, getting the current value.

Methods

impl<T: Clone> OrthoProj<T>

fn new(size: u32, lat: f32, lon: f32, default: T) -> Self

Create a new orthographic projection with width & height of size, centred on lat and lon. default is the default value

fn new_with_bg(size: u32, lat: f32, lon: f32, bg: T, surface: T) -> Self

Create a new OrthoProj, size and lon/lat, but the background (non-sphere) is bg, and surface is used for values on the sphere.

fn xy_for_pos(&self, lat: f32, lon: f32) -> Option<(u32, u32)>

For this projection, what would be the pixel x/y values for this point. None if the lat/lon lies outside the visible area.

fn set(&mut self, lat: f32, lon: f32, value: T)

Set the value of lat, lon to value

fn get(&self, lat: f32, lon: f32) -> &T

For lat/lon what is the currently stored value?

fn get_pixel(&self, x: u32, y: u32) -> &T

What is the current value of pixel x, y
