Struct rasterize::Shape

pub struct Shape {
    pub start: usize,
    pub width: usize,
    pub height: usize,
    pub row_stride: usize,
    pub col_stride: usize,
}

Shape defines size and layout of the data inside an image

Fields

start: usize

Offset of the first element

width: usize

Width of the image

height: usize

Height of the image

row_stride: usize

How many elements we need to skip to get to the next row.

col_stride: usize

How many elements we need to skip to get to the next column.

Implementations

impl Shape

pub fn simple(height: usize, width: usize) -> Self

Crate shape for a simple image with zero offset, and row-major order

pub fn offset(&self, row: usize, col: usize) -> usize

Convert row and column pair to the data offset

pub fn nth(&self, n: usize) -> Option<(usize, usize)>

Get row and column pair by its index

pub fn size(&self) -> Size

Get the size of the image

Trait Implementations

impl Clone for Shape

fn clone(&self) -> Shape

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Shape

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Shape

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Shape

fn eq(&self, other: &Shape) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
