Type Definition imgref::ImgRef

type ImgRef<'a, Pixel> = Img<&'a [Pixel]>;

Reference to pixels inside another image. Pass this structure by value (i.e. ImgRef, not &ImgRef).

Only width of pixels of every stride can be modified. The buf may be longer than height*stride, but the extra space should be ignored.

Methods

impl<'a, T> ImgRef<'a, T>

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

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

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>

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

Deprecated

: Size of this buffer is unpredictable. Use .rows() instead

Deprecated

Note: it iterates all pixels in the underlying buffer, not just limited by width/height.

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>

Trait Implementations

impl<'a, T> Copy for ImgRef<'a, T>

References (ImgRef) should be passed "by value" to avoid a double indirection of &Img<&[]>.
