Class

VisualDropShadow

ChartForgeX.Effects

Namespace: ChartForgeX.Effects
Assembly: ChartForgeX
Source: VisualDropShadow.cs:22
Modifiers: sealed

Immutable alpha shadow for a captured viewport or a retained native surface.

Inheritance

object
VisualDropShadow

Remarks

Offsets and signed spread use integer logical units, multiplied once by capture density. Positive spread dilates source alpha; negative spread erodes it with transparent exterior samples. Gaussian targets use the existing three-box approximation and one final sRGB RGBA8 conversion.

Constructors

public VisualDropShadow(ChartColor color, int offsetX, int offsetY, double sigmaX, double? sigmaY = null, int spread = 0, bool orderedDither = true, double opacity = 1, ChartRect? relativeRegion = null)

VisualDropShadow.cs:22

Creates a literal alpha shadow. No existing scene or theme opts into it automatically.

Parameters

color ChartForgeX.Primitives.ChartColor required: Resolved shadow tint; its alpha multiplies captured source alpha once.
offsetX int required: Signed horizontal logical-pixel offset.
offsetY int required: Signed vertical logical-pixel offset.
sigmaX double required: Finite nonnegative horizontal target, at most 128 device pixels after density conversion.
sigmaY double? = null optional: Optional vertical target; null uses sigmaX.
spread int = 0 optional: Signed integer logical radius; dilation when positive, erosion when negative.
orderedDither bool = true optional: Independent finite 0..1 tint opacity; applied once before final byte conversion.
opacity double = 1 optional: Optional positive shadow-only region relative to source geometry, excluding stroke. Original source is retained.
relativeRegion ChartForgeX.Primitives.ChartRect? = null optional: Whether final RGBA8 conversion uses the existing layer-local Bayer pattern.
