Struct image2::ImageBuf

pub struct ImageBuf<T: Type, C: Color> { /* fields omitted */ }

Image implementation using Vec<T> to store data

Methods

impl<T: Type, C: Color> ImageBuf<T, C>

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

Create a new ImageBuf with the given size

pub fn inner(self) -> Vec<T>

Convert the ImageBuf back to the underlying data buffer

pub fn new_like(&self) -> Self

Create a new image with the same type, shape and color as an existing image

pub fn new_like_with_type<U: Type>(&self) -> ImageBuf<U, C>

Create a new image with the given type and the same shape and color

pub fn new_like_with_color<D: Color>(&self) -> ImageBuf<T, D>

Create a new image with the given color and the same shape and type

pub fn new_from(width: usize, height: usize, data: Vec<T>) -> Self

Create a new image from existing data

Note: This function does not do bounds checking, so you need to ensure that data is the correct length to handle the specified width and height
