Lut.BuildFromSpline Method

Public Sub BuildFromSpline ( _
	points As PointF(), _
	extended As Boolean _
)

public void BuildFromSpline(
	PointF[] points,
	bool extended
)

Parameters

points

Type: System.Drawing.PointF []

Array of curve points. Coordinates are normalized on maximum possible luminosity value, i.e. you specify values in range [0, 1] and they are stretched either to [0, 255] or [0, 65535] depending on extended property value. Note, you still can specify values that are out of [0, 1] range, and algorithm automatically truncates the curve. If all points will be strictly inside of this range, algorithm will add points at:

• x equal to 0 and y equal to Y-coordinate of the leftmost point.
• x equal to 1 and y equal to Y-coordinate of the rightmost point.

extended

Type: System.Boolean

Value that specifies if LUTshould be build for extended (16 bits per channel) or non-extended (8 bits per channel) bitmaps. If it is true, LUT entries number is 65536 and maximum value is 65535, otherwise entries number is 256 and maximum value is 255.
