Struct GrayPixmap 

pub struct GrayPixmap {
    pub width: u32,
    pub height: u32,
    pub data: Vec<u8>,
}

An 8-bit grayscale image, 1 byte per pixel.

Row-major, top-to-bottom. data.len() == width * height. Produced by Pixmap::to_gray8 or [crate::djvu_render::render_gray8].

Fields

width: u32

height: u32

data: Vec<u8>

Grayscale pixel data, row-major. Length = width * height.

Implementations

impl GrayPixmap

pub fn get(&self, x: u32, y: u32) -> u8

Get the luminance value at pixel (x, y).

Trait Implementations

impl Clone for GrayPixmap

fn clone(&self) -> GrayPixmap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GrayPixmap

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

Formats the value using the given formatter.

impl Default for GrayPixmap

fn default() -> GrayPixmap

Returns the “default value” for a type.

impl PartialEq for GrayPixmap

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

Tests for self and other values to be equal, and is used by ==.

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

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