A 2-dimensional buffer of pixel data in memory.
Pixels is a concrete representation of pixel data in memory, and is a lightweight wrapper around the raw bytes represented by a TypedDataList; but cannot be extended or implemented (similar to TypedDataList).
In most cases either IntPixels or Float32x4Pixels will be used directly.

Methods
-
blit<
S> (Buffer< S> from, {Rect? source, Pos? target, BlendMode blend = BlendMode.srcOver}) → void -
Blits, or copies with blending, the pixel data from a source buffer to
thisbuffer. -
blitUnsafe<
S> (Buffer< S> from, {Rect? source, Pos? target, BlendMode blend = BlendMode.srcOver}) → void -
Blits, or copies with blending, the pixel data from a source buffer to
thisbuffer. -
clear(
[Rect? target]) → void - Clears the buffer to the PixelFormat.zero value.
-
clearUnsafe(
[Rect? target]) → void - Clears the buffer to the PixelFormat.zero value.
-
compare(
Buffer< T> other, {double epsilon = 1e-10}) → ComparisonResult<T> -
Compares the buffer to another buffer and returns the result.
