Microsoft.Graphics.Canvas.Effects Namespace

This namespace provides image manipulation effects such as blur and saturation.

Effects are a type of ICanvasImage, so they can be displayed using DrawImage(ICanvasImage) or CanvasImageBrush. The source data fed into an effect is also of type ICanvasImage, which allows you to connect either a bitmap or another effect. Complex image processing graphs can be constructed by chaining many effects together.

Classes
  ClassDescription

Public classCompositeEffect
Combines two or more images.
Public classContrastEffect

Public classConvolveMatrixEffect
[NoComposition] Applies an arbitrary 2D filter kernel to an image. This can perform operations such as edge detect, emboss, sharpen, or blur.

Public classCrossFadeEffect
[Win10_14393] Cross-fades (interpolates) between two images.

Public classDisplacementMapEffect
[NoComposition] Displaces the pixels of an input image by the intensity values of a second image.
Public classDistantDiffuseEffect
Lighting effect creates an image that appears to be an illuminated non-reflective surface. This effect uses the alpha channel as a height map, and lights it with an infinitely distant light source (such as the sun). Note, height map is not supported with Composition.
Public classDistantSpecularEffect
Lighting effect creates an image that appears to be a reflective surface. This effect uses the alpha channel as a height map, and lights it with an infinitely distant light source (such as the sun) applying the specular portion of the Phong lighting model. Note, height map is not supported with Composition.

Public classEffectTransferTable3D
[Win10] A three dimensional lookup table, for use with TableTransfer3DEffect.

[Win10] Inverts the colors of an image.
Public classLinearTransferEffect
[NoComposition] Alters the colors of an image by applying a per-channel linear transfer function.
Public classLuminanceToAlphaEffect

Public classMorphologyEffect
[NoComposition] Thins or thickens edge boundaries in an image. This effect uses a filter kernel that is 2 times the size you specify. The kernel is centered on the pixel being calculated, and returns the maximum value in the kernel (if dilating) or minimum value (if eroding).
Public classOpacityEffect
[Win10_14393] Changes the opacity (alpha) of an image.
Public classOpacityMetadataEffect
[NoComposition] Marks an area of an input image as opaque, which can enable internal rendering optimizations.
Public classCode examplePixelShaderEffect
[NoComposition] Custom image effect which uses a pixel shader to apply arbitrary user-defined processing.
Public classPointDiffuseEffect
Lighting effect creates an image that appears to be an illuminated non-reflective surface. This effect uses the alpha channel as a height map, and lights it with a point light source. Note, height map is not supported with Composition.
Public classPointSpecularEffect
Lighting effect creates an image that appears to be a reflective surface. This effect uses the alpha channel as a height map, and lights it with a point light source applying the specular portion of the Phong lighting model. Note, height map is not supported with Composition.
Public classPosterizeEffect
[Win10] [NoComposition] Reduces the number of unique colors in an image.
Public classPremultiplyEffect

Public classSharpenEffect
[Win10] [NoComposition] Sharpens the image.
Public classSpotDiffuseEffect
Lighting effect creates an image that appears to be an illuminated non-reflective surface where the light source is limited to a directed cone of light. This effect uses the alpha channel as a height map, and lights it with a point light source. Note, height map is not supported with Composition.
