sample()

CRGB fl::sample	(	const CRGB *	grid,
		const XYMap &	xyMap,
		float	x,
		float	y,
		SampleMode	mode = SampleMode::SAMPLE_BILINEAR )

Sample a pixel from a 2D CRGB grid at floating-point coordinates.

Parameters

grid	Pixel buffer (row-major or XYMap-indexed)
xyMap	Coordinate-to-index mapping for the grid
x	Floating-point x coordinate
y	Floating-point y coordinate
mode	Interpolation mode (default: SAMPLE_BILINEAR)
