[−][src]Type Definition imgref::ImgRefMut

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

Same as ImgRef, but mutable Pass this structure by value (i.e. ImgRef, not &ImgRef).

Methods

impl<'a, T> ImgRefMut<'a, T>[src]

#[must_use]pub fn sub_image(
    &'a mut self,
    left: usize,
    top: usize,
    width: usize,
    height: usize
) -> ImgRef<'a, T>[src]

Turn this into immutable reference, and slice a subregion of it

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

Trim this image without copying. Note that mutable borrows are exclusive, so it's not possible to have more than one mutable subimage at a time.

#[must_use]pub fn as_ref(&self) -> ImgRef<T>[src]

Make mutable reference immutable
