G2DCoordinateSystemLogicalToLayerCoordinatesAndDirection Method

Converts logical coordinates along an isoline to layer coordinates and the appropriate derivative.

Namespace: Altaxo.Graph.Gdi
Assembly: AltaxoBase (in AltaxoBase.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
Copy
public abstract bool LogicalToLayerCoordinatesAndDirection(
	Logical3D r0,
	Logical3D r1,
	double t,
	out double ax,
	out double ay,
	out double adx,
	out double ady
)

Parameters

r0  Logical3D
Logical position of starting point of the isoline.
r1  Logical3D
Logical position of end point of the isoline.
t  Double
Parameter between 0 and 1 that determines the point on the isoline. A value of 0 denotes the starting point of the isoline, a value of 1 the end point. The logical coordinates are linear interpolated between starting point and end point.
ax  Double
Layer coordinate x of the isoline point.
ay  Double
Layer coordinate y of the isoline point.
adx  Double
Derivative of layer coordinate x with respect to parameter t at the point (ax,ay).
ady  Double
Derivative of layer coordinate y with respect to parameter t at the point (ax,ay).

Return Value

Boolean
True if the conversion was sucessfull, otherwise false.
