SkiaSharp effects

The SkiaSharp SKPaint class defines six properties that can be classified under the general term of effects. These are properties that alter the normal display of graphics in some way. The SkiaSharp effects fall into six categories:

Path Effects

Set the PathEffect property of SKPaint to an object of type SKPathEffect to display dashed lines, or to stroke or fill an area with a pattern created from paths. The path effect was covered earlier in this series in the article Path Effects in SkiaSharp.

Shaders

Set the Shader property of SKPaint to an object of type SKShader to display linear or circular gradients, tiled bitmaps, and Perlin noise patterns.

Blend Modes

Set the BlendMode property of SKPaint to a member of the SKBlendMode enumeration to govern what happens when a source graphic is displayed on a destination. SkiaSharp supports all the CSS compositing and blend modes, including the Porter-Duff modes, separable blend modes, and non-separable blend modes.

Mask Filters

Set the MaskFilter property of SKPaint to an object of type SKMaskFilter for blurs and other alpha effects.

Image Filters

Set the ImageFilter property of SKPaint to an object of type SKImageFilter for blurring bitmaps and creating drop shadows, embossing, or engraving effects.

Color Filters

Set the ColorFilter property of SKPaint to an object of type SKColorFilter to alter colors using tables or matrix transforms.
