Struct Image 

pub struct Image {
    pub width: u32,
    pub height: u32,
    pub data: Vec<u8>,
    pub filter_type: FilterType,
}

Image

Contains pixel data for a width * height image in RGBA format. Data is stored as 4 * w * h 8-bit r, g, b, a values.

Fields

width: u32

height: u32

data: Vec<u8>

filter_type: FilterType

Implementations

impl Image

pub fn new(width: u32, height: u32, filter_type: FilterType) -> Self

Creates a new black/transparent image filled with zeros (RGBA 8-bit).

pub fn from_data( width: u32, height: u32, filter_type: FilterType, data: Vec<u8>, ) -> Self

Wraps an existing Vec RGBA buffer.

pub fn from_pixels( width: u32, height: u32, filter_type: FilterType, pixels: Vec<Color>, ) -> Self

Creates an image from a collection of Colors.

Color channels are expected to be normalized to [0.0, 1.0] and are converted to 8-bit [0, 255] values.

pub fn with_filter_type(self, filter_type: FilterType) -> Self

Returns image with filter type.

pub fn set_pixel(&mut self, x: u32, y: u32, color: Color)

Sets the RGBA color [r, g, b, a] for pixel at (x, y).

Color channels are expected to be normalized to [0.0, 1.0].

pub fn get_pixel(&self, x: u32, y: u32) -> Option<Color>

Gets the RGBA color [r, g, b, a] at (x, y). Returns None if out of bounds.

Color channels are returned normalized to [0.0, 1.0].

pub fn clear(&mut self, color: [f32; 4])

Clears the image using a single RGBA color.

Color channels are expected to be normalized to [0.0, 1.0].

pub fn to_dynamic(&self) -> DynamicImage

Converts this struct directly into image::DynamicImage.

pub fn from_dynamic(dynamic: &DynamicImage, filter_type: FilterType) -> Self

Creates an Image from an image::DynamicImage.

Pixel data is stored directly as normalized 8-bit RGBA.

pub fn to_rgba8_buffer(&self) -> RgbaImage

Converts this image to an 8-bit RGBA ImageBuffer.

This clones the underlying data because the returned ImageBuffer owns it.

Trait Implementations

impl Clone for Image

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Image

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

Formats the value using the given formatter.

impl Default for Image

fn default() -> Self

Returns the “default value” for a type.
