Class

ChartPolarProjection

ChartForgeX.Rendering

Namespace: ChartForgeX.Rendering
Assembly: ChartForgeX
Source: ChartPolarProjection.cs:34
Modifiers: sealed

A detached directional and radius projection captured by a usable continuous Polar preparation.

Inheritance

object
ChartPolarProjection

Remarks

Angular windows clip a sector; they never stretch or rewrite source bearings. Each radius window uniformly magnifies captured full-domain geometry and crops an annulus. The nearer projected boundary is an inner aperture, not a nonlinear remapping to the center. Original cubic curves, tangents and closed areas remain intact before the shared SVG/native-raster paint clip.

Methods

public ChartAxisWindow? ConstrainRadius(ChartAxisWindow window, ChartAxisSide axis = Primary) #

ChartPolarProjection.cs:40

Confines a requested radius window using the captured axis transform. Null means the full domain.

Parameters

window ChartForgeX.Core.ChartAxisWindow required
axis ChartForgeX.Core.ChartAxisSide = Primary optional

Returns

ChartAxisWindow?

public bool Contains(double angle, double radius, ChartAxisSide axis = Primary) #

ChartPolarProjection.cs:69

Tests source-mark membership without filtering or rewriting captured observations.

Parameters

angle double required
radius double required
axis ChartForgeX.Core.ChartAxisSide = Primary optional

Returns

bool

public double GetInnerRadius(ChartAxisSide axis = Primary) #

ChartPolarProjection.cs:44

Gets the selected radius axis's captured inner aperture in logical drawing units.

Parameters

axis ChartForgeX.Core.ChartAxisSide = Primary optional

Returns

double

public double GetOuterRadius(ChartAxisSide axis = Primary) #

ChartPolarProjection.cs:46

Gets the selected radius axis's captured outer crop radius in logical drawing units.

Parameters

axis ChartForgeX.Core.ChartAxisSide = Primary optional

Returns

double

public ChartAxisWindow GetRadiusWindow(ChartAxisSide axis = Primary, bool fullDomain = false) #

ChartPolarProjection.cs:34

Gets the current or full source-radius window for an available selected axis.

Parameters

axis ChartForgeX.Core.ChartAxisSide = Primary optional
fullDomain bool = false optional

Returns

ChartAxisWindow

public ChartPolarViewport? Pan(double clockwiseAngleDelta, double outwardLogicalRadiusDelta, ChartPolarNavigationAxes axes = Angle, Radius)

ChartPolarProjection.Navigation.cs:74

Moves selected captured windows by clockwise screen radians and outward logical drawing units.

Parameters

clockwiseAngleDelta double required
outwardLogicalRadiusDelta double required
axes ChartForgeX.Core.ChartPolarNavigationAxes = Angle, Radius optional

Returns

ChartPolarViewport? An immutable native request, or null for the complete view.

Exceptions

ArgumentOutOfRangeException – A delta, selected axes or resulting span is invalid or unrepresentable.
NotSupportedException – A selected radius axis is unavailable.

public ChartPoint Project(double angle, double radius, ChartAxisSide axis = Primary) #

ChartPolarProjection.cs:51

Maps raw radians and a supported nonnegative radius onto the uniformly magnified full-domain geometry.

Parameters

angle double required
radius double required
axis ChartForgeX.Core.ChartAxisSide = Primary optional

Returns

ChartPoint

public double UnprojectRadius(double logicalRadius, ChartAxisSide axis = Primary) #

ChartPolarProjection.cs:63

Converts a nonnegative logical distance from the center into the selected source radius.

Parameters

logicalRadius double required
axis ChartForgeX.Core.ChartAxisSide = Primary optional

Returns

double

Zoom 2 overloads

public ChartPolarViewport? Zoom(double factor, ChartPolarNavigationAxes axes = Angle, Radius) #

ChartPolarProjection.Navigation.cs:16

Crops selected captured coordinates around the visible sector and selected-annulus midpoint.

Parameters

factor double required
axes ChartForgeX.Core.ChartPolarNavigationAxes = Angle, Radius optional

Returns

ChartPolarViewport? An immutable native request, or null for the complete view.

Exceptions

ArgumentOutOfRangeException – The factor or selected axes are invalid, or a span is unrepresentable.
NotSupportedException – A selected radius axis is unavailable.

public ChartPolarViewport? Zoom(double factor, ChartPoint logicalAnchor, ChartPolarNavigationAxes axes = Angle, Radius) #

ChartPolarProjection.Navigation.cs:35

Crops selected captured coordinates around a logical pointer anchor. Factors above one zoom in.

Parameters

factor double required
logicalAnchor ChartForgeX.Primitives.ChartPoint required
axes ChartForgeX.Core.ChartPolarNavigationAxes = Angle, Radius optional

Returns

ChartPolarViewport? An immutable native request, or null when all coordinates return to their complete domains.

Exceptions

ArgumentOutOfRangeException – The factor, anchor or selected axes are invalid, or a span is unrepresentable.
NotSupportedException – A selected radius axis is unavailable.
