impl<T> PaddingStrategy<T> for ConstantPadding<T>
where T: Copy,

Source§

fn pad( &self, image: ArrayView<'_, T, Ix3>, padding: (usize, usize), ) -> ArrayBase<OwnedRepr<T>, Ix3>

Taking in the image data and the margin to apply to rows and columns returns a padded image
Source§

fn get_pixel( &self, image: ArrayView<'_, T, Ix3>, index: (isize, isize), ) -> Option<Array1<T>>

Taking in the image data and row and column return the pixel value if the coordinates are within the image bounds this should probably not be used in the name of performance
Source§

fn get_value( &self, image: ArrayView<'_, T, Ix3>, index: (isize, isize, usize), ) -> Option<T>

Gets a value for a channel rows and columns can exceed bounds but the channel index must be present
Source§

fn will_pad(&self, _coord: Option<(isize, isize)>) -> bool

Returns true if the padder will return a value for (row, col) or if None if it can pad an image at all. NoPadding is a special instance which will always be false
Source§

impl<T> PartialEq for ConstantPadding<T>
where T: Copy + PartialEq,

Source§

fn eq(&self, other: &ConstantPadding<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
