}Expand description
Trait to inspect an image.
Associated Types
type InnerImageView: GenericImageView<Pixel = Self::Pixel>
type InnerImageView: GenericImageView<Pixel = Self::Pixel>
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.
Required methods
Returns the pixel located at (x, y). Indexed from top left.
Panics
Panics if (x, y) is out of bounds.
TODO: change this signature to &P
fn inner(&self) -> &Self::InnerImageView
fn inner(&self) -> &Self::InnerImageView
Returns a reference to the underlying image.
Provided methods
Returns true if this x, y coordinate is contained inside the image.
unsafe fn unsafe_get_pixel(&self, x: u32, y: u32) -> Self::Pixel
unsafe fn unsafe_get_pixel(&self, x: u32, y: u32) -> Self::Pixel
Returns an Iterator over the pixels of this image. The iterator yields the coordinates of each pixel along with their value
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.
