Fields

images: Vec<&'a Image<T, C>>

Input images

pixel: Option<(Point, Pixel<C>)>

Input pixel

Implementations

impl<'a, T: 'a + Type, C: 'a + Color> Input<'a, T, C>

pub fn new(images: &'a [&'a Image<T, C>]) -> Self

Create new Input

pub fn with_pixel(self, point: Point, pixel: Pixel<C>) -> Self

Add chained pixel data

pub fn without_pixel(self) -> Self

Remove chained pixel data

pub fn pixel(&self) -> Option<&(Point, Pixel<C>)>

Returns optional pixel value

pub fn len(&self) -> usize

Get number of images

pub fn is_empty(&self) -> bool

Returns true when there are no inputs

pub fn images(&self) -> &[&Image<T, C>]

Get input images

pub fn get_pixel(
    &self,
    pt: impl Into<Point>,
    image_index: Option<usize>
) -> Pixel<C>

Get input pixel at pt - if pt matches the stored pixel from a preview computation then that pixel will be returned instead of the actual input pixel. If image_index is not None then input from the image with that index will be used.

pub fn get_f(
    &self,
    pt: impl Into<Point>,
    c: Channel,
    image_index: Option<usize>
) -> f64

Get input float value - if pt matches the stored pixel from a preview computation then that pixel will be returned instead of the actual input pixel. If image_index is not None then input from the image with that index will be used.

pub fn new_pixel(&self) -> Pixel<C>

Create a new pixel
