SpotSpecularEffect Class |
Namespace: Microsoft.Graphics.Canvas.Effects
public sealed class SpotSpecularEffect : ICanvasEffect, IGraphicsEffect, IGraphicsEffectSource, ICanvasImage, IDisposable
The SpotSpecularEffect type exposes the following members.
Name | Description | |
---|---|---|
SpotSpecularEffect | Initializes a new instance of the SpotSpecularEffect class. |
Name | Description | |
---|---|---|
BufferPrecision | Specifies what precision to use for intermediate buffers when drawing this effect. | |
CacheOutput | Enables caching the output from drawing this effect. | |
Focus | Focus of the spot light. Default value 1. | |
HeightMapInterpolationMode | [NoComposition] Interpolation mode used to filter the height map.
Default value Linear. | |
HeightMapKernelSize | [NoComposition] Size of the Sobel filter kernel used to convert the input heightmap to
surface normal vectors. Default value (1,1). | |
HeightMapScale | [NoComposition] Height map scale factor in the Z direction. Default value 1. | |
LightColor | Color of the incoming light. Default value white. | |
LightColorHdr | High-dynamic-range color of the incoming light. Default value white. | |
LightPosition | Position of the light source. Default value (0,0,0). | |
LightTarget | Target that the spot light is pointing at. Default value (0,0,0). | |
LimitingConeAngle | Angle (in radians) that restricts the region where light is projected.
No light is projected outside the cone. Default value pi/2. | |
Name | Attaches a user-defined name string to the effect. | |
Source | Gets or sets the input source for SpotSpecular effect. | |
SpecularAmount | Intensity of the specular light. Default value 1. | |
SpecularExponent | Specular power for the Phong lighting model. Larger values produce
more sharply defined highlights. Default value 1. |
Name | Description | |
---|---|---|
Dispose | Releases all resources used by the effect. | |
GetBounds(ICanvasResourceCreator) | Retrieves the bounds of this SpotSpecularEffect. | |
GetBounds(ICanvasResourceCreator, Matrix3x2) | Retrieves the bounds of this SpotSpecularEffect. | |
GetInvalidRectangles | Queries what regions of the effect output have changed since it was last drawn. | |
GetRequiredSourceRectangle | Queries what part of an effect source image is needed to draw an output region. | |
GetRequiredSourceRectangles | Queries what parts of the effect source images are needed to draw an output region. | |
InvalidateSourceRectangle | Notifies the effect that one of its source images has changed. |
This Windows Runtime type corresponds to the D2D Spot-specular lighting effect.
