BufferPrecision | Specifies what precision to use for intermediate buffers when drawing this effect. | |
CacheOutput | Enables caching the output from drawing this effect. | |
InterpolationMode | Gets or sets the interpolation mode. | |
MaintainSize | Specifies whether the image will be scaled such that the result fits
within the original rectangle without any invalid regions, no matter how

GetBounds(ICanvasResourceCreator, Matrix3x2) | Retrieves the bounds of this StraightenEffect. | |
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. | |

InvalidateSourceRectangle | Notifies the effect that one of its source images has changed. |
Supported by Win2D but not Windows.UI.Composition.
This effect is useful for correcting photos that were taken at an angle so their horizon is not quite horizontal.
This Windows Runtime type corresponds to the D2D Straighten effect.
