| 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.

color channels set to 0. Use it to make a semitransparent overlay based on the
brightness of the source image.
|
| MorphologyEffect | [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).
|
| OpacityEffect | [Win10_14393]
Changes the opacity (alpha) of an image.
|
| OpacityMetadataEffect | [NoComposition]

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.
|

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

opaque for higher alpha values and more transparent for lower alpha
values. You can set the amount of blur and the color of the shadow.
|
| SharpenEffect | [NoComposition]
Sharpens the image.
|
| SpotDiffuseEffect |
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

source. Note, height map is not supported with Composition.

the light source is limited to a directed cone of light. This effect uses the
