public sealed class InvertEffect : ICanvasEffect, IGraphicsEffect, IGraphicsEffectSource, ICanvasImage, IDisposable
The InvertEffect type exposes the following members.
Name | Description | |
---|---|---|
InvertEffect | Initializes a new instance of the InvertEffect 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. | |
Name | Attaches a user-defined name string to the effect. | |
Source | Gets or sets the input source for Invert effect. |
Name | Description | |
---|---|---|
Dispose | Releases all resources used by the effect. | |
GetBounds(ICanvasResourceCreator) | Retrieves the bounds of this InvertEffect. | |
GetBounds(ICanvasResourceCreator, Matrix3x2) | Retrieves the bounds of this InvertEffect. | |
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. |
Effect inputs and outputs are assumed to be in premultiplied alpha format, but this effect operates internally on straight alpha data, so its input values will be unpremultiplied, then the invert applied, and finally the result converted back to premultiplied format.
