Implementations

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

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

Create new Input

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

Add chained pixel data

pub fn without_pixel(self) -> Self[src]

Remove chained pixel data

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

Returns optional pixel value

pub fn len(&self) -> usize[src]

Get number of images

pub fn is_empty(&self) -> bool[src]

Returns true when there are no inputs

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

Get input images

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

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[src]

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>[src]

Create a new pixel
