fn dimensions(&self) -> (u32, u32)
[src]
The width and height of this image.
fn bounds(&self) -> (u32, u32, u32, u32)
[src]
The bounding rectangle of this image.
fn get_pixel(&self, x: u32, y: u32) -> I::Pixel
[src]
Returns the pixel located at (x, y) Read more

fn in_bounds(&self, x: u32, y: u32) -> bool
[src]
Returns true if this x, y coordinate is contained inside the image.

ⓘImportant traits for Pixels<'a, I>fn pixels(&self) -> Pixels<Self>
[src]
Returns an Iterator over the pixels of this image. The iterator yields the coordinates of each pixel along with their value Read more
ⓘImportant traits for MutPixels<'a, I>fn pixels_mut(&mut self) -> MutPixels<Self>
[src]
: This cannot be implemented safely in Rust. Please use the image buffer directly.
Returns an Iterator over mutable pixels of this image. The iterator yields the coordinates of each pixel along with a mutable reference to them. Read more
