Type Definition imgref::ImgVec

type ImgVec<Pixel> = Img<Vec<Pixel>>;

Image owning its pixels.

A 2D array of pixels. The pixels are oriented top-left first and rows are stride pixels wide.

If size of the buf is larger than width*height, then any excess space is a padding (see width_padded()/height_padded()).

Methods

impl<'a, T: Copy> ImgVec<T>

Important traits for PixelsIter<'a, T>

impl<'a, T: Copy + 'a> Iterator for PixelsIter<'a, T> type Item = T;

pub fn pixels(&self) -> PixelsIter<T>

impl<T> ImgVec<T>

pub fn sub_image_mut(
    &mut self,
    left: usize,
    top: usize,
    width: usize,
    height: usize
) -> ImgRefMut<T>

Create a mutable view into a region within the image. See sub_image() for read-only views.

pub fn sub_image(
    &self,
    left: usize,
    top: usize,
    width: usize,
    height: usize
) -> ImgRef<T>

Make a reference for a part of the image, without copying any pixels.

pub fn as_ref(&self) -> ImgRef<T>

Make a reference to this image to pass it to functions without giving up ownership

The reference should be passed by value (ImgRef, not &ImgRef).

If you need a mutable reference, see as_mut() and sub_image_mut()

pub fn as_mut(&mut self) -> ImgRefMut<T>

Make a mutable reference to the entire image

The reference should be passed by value (ImgRefMut, not &mut ImgRefMut).

See also sub_image_mut() and rows_mut()

pub fn iter(&self) -> Iter<T>

Deprecated:

Size of this buffer may be unpredictable. Use .rows() instead

Important traits for RowsIter<'a, T>

impl<'a, T: 'a> Iterator for RowsIter<'a, T> type Item = &'a [T];

pub fn rows(&self) -> RowsIter<T>

Iterate over rows of the image as slices

Each slice is guaranteed to be exactly width pixels wide.

Important traits for RowsIterMut<'a, T>

impl<'a, T: 'a> Iterator for RowsIterMut<'a, T> type Item = &'a mut [T];

pub fn rows_mut(&mut self) -> RowsIterMut<T>

Iterate over rows of the image as mutable slices

Each slice is guaranteed to be exactly width pixels wide.
