Struct Alpha16 

pub struct Alpha16 {
    pub pix: Vec<u8>,
    pub stride: usize,
    /* private fields */
}

Alpha16 is an in-memory image whose At method returns color::Alpha16 values.

Fields

pix: Vec<u8>

stride: usize

stride is the pix stride (in bytes) between vertically adjacent pixels.

Implementations

impl Alpha16

pub fn new(r: &Rectangle) -> Self

new returns a new Alpha16 image with the given bounds.

pub fn pix_offset(&self, x: isize, y: isize) -> usize

pix_offset returns the index of the first element of pix that corresponds to the pixel at (x, y).

Trait Implementations

impl Debug for Alpha16

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

Formats the value using the given formatter.

impl Image for Alpha16

fn color_model(&self) -> Model

color_model returns the Image’s color model.

fn bounds(&self) -> &Rectangle

bounds returns the domain for which At can return non-zero color:: The bounds do not necessarily contain the point (0, 0).

fn at(&self, x: isize, y: isize) -> Color

at returns the color of the pixel at (x, y). at(bounds().min.x, bounds().min.y) returns the upper-left pixel of the grid. at(bounds().max.x-1, bounds().max.y-1) returns the lower-right one.

fn set(&mut self, x: isize, y: isize, c: &Color)

fn opaque(&self) -> bool

opaque scans the entire image and reports whether it is fully opaque.

fn stride(&self) -> usize

stride returns the pix stride (in bytes) between vertically adjacent pixels.

fn pix(&self) -> &Vec<u8>

pix returns the image pixel data. Format of the data depends on the image type.

fn get_pix_mutable(&mut self) -> &mut Vec<u8>

get_pix_mutable returns the image data for editing. Format of the data depends on the image type.

fn bytes_per_pixel(&self) -> usize

bytes_per_pixel return how many bytes is used per pixel

fn deep_equal(&self, other: &dyn Image) -> bool

deep_equal checks that two images are exactly the same

fn get_line_data(&self, y: isize) -> &[u8]

get_line_data returns data that encode one line of pixels.
