A 2-dimensional view of pixel data T in memory.
Buffer is analogous to a (read only) Iterable of pixels, but with a 2-dimensional structure. It is used to represent pixel data in memory without copying it, but also without exposing the raw memory.
In most cases buffers will be used ephemerally; Pixels is an actual representation of pixel data.

Methods
-
compare(
Buffer< T> other, {double epsilon = 1e-10}) → ComparisonResult<T> - Compares the buffer to another buffer and returns the result.
-
contains(
Pos pos) → bool - Returns whether the given position is within the bounds of the buffer.
-
get(
Pos pos) → T - Returns the pixel at the given position.
-
getRect(
Rect rect) → Iterable< T> -
Returns a lazy iterable of pixels in the rectangle defined by
rect. -
getRectUnsafe(
Rect rect) → Iterable< T> -
Returns a lazy iterable of pixels in the rectangle defined by
rect. -
getUnsafe(
Pos pos) → T - Returns the pixel at the given position without bounds checking.
-
map(
T convert(T)) → Buffer< T> - Returns a lazy buffer buffer that converts pixels with the given function.
-
mapConvert<
R> (PixelFormat< R, void> format) → Buffer<R> -
Returns a lazy buffer that converts pixels to the given
format. -
mapIndexed(
T convert(Pos, T)) → Buffer< T> - Returns a lazy buffer that converts pixels with the given function.
-
mapRect(
Rect bounds) → Buffer< T> -
Returns a lazy buffer that clips the buffer to the given
bounds. -
mapScaled(
int scale) → Buffer< T> - Returns a lazy buffer that scales the buffer by the given factor.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
override
Operators

operator ==(
Object other) → bool -
The equality operator.

Static Methods
-
bufferToLongString<
T> (Buffer< T> buffer) → String - Converts a Buffer to a string like Buffer.toString.
