PImage class

An image in Processing.

PImage provides APIs for accessing and altering bitmap data.

Use toFlutterImage to obtain a dart:ui Image to draw with Flutter.

Constructors

PImage.empty(int width, int height, ImageFileFormat format)

PImage.fromPixels(int width, int height, ByteData pixels, ImageFileFormat format)

Properties

Methods

blend(PImage other, {required Rect sourceRect, required Rect destRect, required SketchBlendMode mode}) → void

Blends pixels from the other image into this PImage, using the given blend mode.

copy([Rect? rect]) → PImage

Copies and returns all, or part of, this PImage.

copyFrom({PImage? source, required Rect sourceRect, required Rect destRect}) → void

Copies pixels into this PImage from the given source, or replicates a region of this PImage within itself if no source is provided.

filter(ImageFilter filter, [double? value]) → void

get(int x, int y) → Color

Returns the ARGB color of the pixel at the given (x, y).

getRegion({required int x, required int y, required int width, required int height}) → Future<PImage>

Creates a returns a new PImage that replicates a region of this PImage, defined by the given (x,y) origin and the given width and height.

loadPixels() → Future<void>

Loads this image's pixels into an pixel in-memory buffer.

mask({PImage? maskImage, List<int>? maskPixels}) → void

Masks this PImage with the given maskImage or the given maskPixels.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

resize({int? width, int? height}) → void

Resizes this PImage to the given width and height.

save(String filePath) → Future<void>

Saves this PImage to a file at the given filePath.

set(int x, int y, Color color) → void

Sets the ARGB color of the pixel at the given (x,y).

setRegion({required PImage image, int x = 0, int y = 0}) → void

Copies the given image into this PImage at the given (x,y).

toFlutterImage() → Future<Image>

Returns a dart:io Image version of this PImage so that it can be drawn with Flutter.

toString() → String

A string representation of this object.

inherited

updatePixels() → Future<void>

Applies all recent operations to the in-memory pixel buffer.

Operators

operator ==(Object other) → bool

The equality operator.
