Struct CanvasVector

Namespace

FlowGraph.Core.Coordinates

Assembly

FlowGraph.Core.dll

A vector/delta in canvas coordinate space.

Canvas vectors represent movements, offsets, and distances in canvas space. Unlike canvas points, vectors are relative (they represent the difference between two points, not an absolute position).

When to use:

• Drag distances in canvas space
• Node movement offsets
• Snap offsets
• Collision avoidance adjustments

public CanvasVector(double DX, double DY)

Parameters

DX double

DY double

Properties

DX

public double DX { get; init; }

Property Value

double

DY

public double DY { get; init; }

Property Value

double

Length

The length (magnitude) of this vector.

public double Length { get; }

Property Value

double

LengthSquared

The squared length of this vector (faster than Length).

public double LengthSquared { get; }

Property Value

double

CanvasVector

Methods

FromCore(Point)

Creates a vector from a core Point (treating it as a delta).

public static CanvasVector FromCore(Point delta)

Parameters

delta Point

Returns

CanvasVector

Normalized()

Returns a normalized (unit length) version of this vector. Returns Zero if this vector has zero length.

public CanvasVector Normalized()

Returns

CanvasVector

ToCore()

Converts to a core Point (for APIs that expect Point as delta).

public Point ToCore()

Returns

Point

ToString()

Returns the fully qualified type name of this instance.

public override string ToString()

Returns

string

The fully qualified type name.
