Underlying image type. This is mainly used by SubImages in order to always have a reference to the original image. This allows for less indirections and it eases the use of nested SubImages. Read more
sourcefn get_pixel(&self, x: u32, y: u32) -> Rgba<u8>
fn get_pixel(&self, x: u32, y: u32) -> Rgba<u8>
Returns the pixel located at (x, y). Indexed from top left. Read more
sourcefn inner(&self) -> &Self::InnerImageView
fn inner(&self) -> &Self::InnerImageView
Returns a reference to the underlying image.
sourcefn in_bounds(&self, x: u32, y: u32) -> bool
fn in_bounds(&self, x: u32, y: u32) -> bool
Returns true if this x, y coordinate is contained inside the image.
sourceunsafe fn unsafe_get_pixel(&self, x: u32, y: u32) -> Self::Pixel
unsafe fn unsafe_get_pixel(&self, x: u32, y: u32) -> Self::Pixel
Returns the pixel located at (x, y). Indexed from top left. Read more

fn pixels(&self) -> Pixels<'_, Self>ⓘNotable traits for Pixels<'a, I>impl<'a, I: GenericImageView> Iterator for Pixels<'a, I> type Item = (u32, u32, I::Pixel);
Returns an Iterator over the pixels of this image. The iterator yields the coordinates of each pixel along with their value Read more
sourcefn view(
&self,
x: u32,
y: u32,

height: u32
) -> SubImage<&Self::InnerImageView>
fn view(
&self,
x: u32,
y: u32,
width: u32,
height: u32
) -> SubImage<&Self::InnerImageView>
Returns an subimage that is an immutable view into this image.
You can use GenericImage::sub_image
if you need a mutable view instead.
The coordinates set the position of the top left corner of the view. Read more
