Methods

any(bool test(num element)) → bool: Checks whether any element of this iterable satisfies test.
inherited
cast<R>() → Iterable<R>: A view of this iterable as an iterable of R instances.
inherited
clone() → PixelUndefined: Returns a copy of the color.
override
contains(Object? element) → bool: Whether the collection contains an element equal to element.
inherited
convert({Format? format, int? numChannels, num? alpha}) → Color: Convert the format and/or the numChannels of the color. If numChannels is 4 and the current color does not have an alpha value, then alpha can specify what value to use for the new alpha channel. If alpha is not given, then maxChannelValue will be used.
override
elementAt(int index) → num: Returns the indexth element.
inherited
every(bool test(num element)) → bool: Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(num element)) → Iterable<T>: Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(num element), {num orElse()?}) → num: The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, num element)) → T: Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<num> other) → Iterable<num>: Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(num element)) → void: Invokes action on each element of this iterable in iteration order.
inherited
getChannel(Channel channel) → num: Get a channel from the color. If the channel isn't available, 0 will be returned.
override
getChannelNormalized(Channel channel) → num: Get the normalized [0, 1] value of a channel from the color. If the channel isn't available, 0 will be returned.
override
join([String separator = ""]) → String: Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(num element), {num orElse()?}) → num: The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(num e)) → Iterable<T>: The current elements of this iterable modified by toElement.
inherited
moveNext() → bool: Move to the next pixel, returning false if it moved past the end of the image data.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
reduce(num combine(num value, num element)) → num: Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
set(Color c) → void: Set the values of this color to the given color.
override
setPosition(int x, int y) → void: Set the coordinates of the pixel.
override
setPositionNormalized(num x, num y) → void: Set the normalized coordinates of the pixel, in the range [0, 1].
override
setRgb(num r, num g, num b) → void: Set the individual r, g, b channels of the color.
override
setRgba(num r, num g, num b, num a) → void: Set the individual r, g, b, a channels of the color.
override
singleWhere(bool test(num element), {num orElse()?}) → num: The single element that satisfies test.
inherited
skip(int count) → Iterable<num>: Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(num value)) → Iterable<num>: Creates an Iterable that skips leading elements while test is satisfied.
inherited
take(int count) → Iterable<num>: Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(num value)) → Iterable<num>: Creates a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) → List<num>: Creates a List containing the elements of this Iterable.
inherited
toSet() → Set<num>: Creates a Set containing the same elements as this iterable.
inherited
toString() → String: Returns a string representation of (some of) the elements of this.
inherited
where(bool test(num element)) → Iterable<num>: Creates a new lazy Iterable with all elements that satisfy the predicate test.
inherited
