import "image/image";

Image class

Contains the image data. For actual painting use the Painter class.

The pixels are stored in a shared array, you can access the same image from different threads.

Initialization

static function create(width: Integer, height: Integer): Image

Creates a new image with given dimensions.

static function load(data: Byte[]): Image

Loads a PNG image from given byte array.

function clone(): Image

Returns a copy of this image.

function get_subimage(x: Integer, y: Integer, width: Integer, height: Integer): Image

Returns a rectangular view to this image (the pixels are shared).

function to_png(): Byte[]

Returns the image encoded in a PNG file format.

Properties

function get_width(): Integer

Returns width of the image.

function get_height(): Integer

Returns height of the image.

function get_stride(): Integer

Returns stride (increments between the rows in pixels array) of the image.

function get_pixels(): Integer[]

Returns shared array with raw pixels.

Operations

function downscale(): Image
function downscale(steps: Integer): Image

Returns downscaled version (halving the resolution) of the image. Optionally you can pass how many steps you want to apply.

function blur(radius: Float)

Applies fast Gaussian blur approximation. The performance is independent of the radius value.

function blur_box(radius: Float)
function blur_box(rx: Float, ry: Float, steps: Integer)

Applies box blur. The performance is independent of the radius value.

function blur_gaussian(radius: Float)

Applies more accurate Gaussian blur approximation. The performance is independent of the radius value.

function remap_color_ramps(table: Byte[])

Applies color remapping for each channel. The table must have either 256 entries (to apply the same to all color channels) or 768 entries (to apply to each color channel independently).

function apply_gamma(value: Float)

Applies gamma correction to the image.
