A 2-dimensional buffer of multi-channel floating point pixel data in memory.
Each pixel is represented by a Float32x4 value, which is a 128-bit SIMD compatible (on supported platforms) floating point vector, and typically (but not necessarily) stores 4 floating point values in the range of 0.0 to 1.0, which allows a higher dynamic range than the 8-bit integer based pixel formats.
Constructors
-
Float32x4Pixels(int width, int height, {PixelFormat<
Float32x4, void> format = floatRgba, Float32x4List? data}) -
Creates a new buffer of multi-channel floating point pixel data.
factory
-
Float32x4Pixels.from(Buffer<
Float32x4> buffer) -
Creates a copy of the given buffer with the same pixel data and
dimensions.
