TopicDescription

IDCompositionAffineTransform2DEffect

The arithmetic composite effect is used to combine 2 images using a weighted sum of pixels from the input images.

IDCompositionAnimation

Represents a function for animating one or more properties of one or more DirectComposition objects.

IDCompositionArithmeticCompositeEffect

The arithmetic composite effect is used to combine 2 images using a weighted sum of pixels from the input images.

IDCompositionBlendEffect

The Blend Effect is used to combine 2 images.

IDCompositionBrightnessEffect

The brightness effect controls the brightness of the image.

IDCompositionColorMatrixEffect

The color matrix effect alters the RGBA values of a bitmap.

IDCompositionCompositeEffect

The composite effect is used to combine 2 or more images. This effect has 13 different composite modes. The composite effect accepts 2 or more inputs. When you specify 2 images, destination is the first input (index 0) and the source is the second input (index 1). If you specify more than 2 inputs, the images are composited starting with the first input and the second and so on.

IDCompositionClip

Represents a clip object that is used to restrict the rendering of a visual subtree to a rectangular area.

IDCompositionDesktopDevice

An application must use the IDCompositionDesktopDevice interface in order to use DirectComposition in a Win32 desktop application. This interface allows the application to connect a visual tree to a window and to host layered child windows for composition

IDCompositionDevice

Serves as a factory for all other DirectComposition objects and provides methods to control transactional composition.

IDCompositionDevice2

Serves as a factory for all other DirectComposition objects and provides methods to control transactional composition.

IDCompositionDevice3

Serves as a factory for all other DirectComposition objects and provides methods to control transactional composition.

IDCompositionDeviceDebug

Provides access to rendering features that help with application debugging and performance tuning. This interface can be queried from the DirectComposition device interface.

IDCompositionEffect

Represents a bitmap effect that modifies the rasterization of a visual's subtree.

IDCompositionEffectGroup

Represents a group of bitmap effects that are applied together to modify the rasterization of a visual's subtree.

IDCompositionFilterEffect

Represents a filter effect.

IDCompositionFloodEffect

The flood effect is used to generate a bitmap based on the specified color and alpha value. You can use this effect when you want a specific color as an input for an effect, like a background color.

IDCompositionGaussianBlurEffect

IDCompositionHueRotationEffect

The hue rotate effect alters the hue of an image by applying a color matrix based on the rotation angle.

IDCompositionLinearTransferEffect

The linear transfer effect is used to map the color intensities of an image using a linear function created from a list of values you provide for each channel.

IDCompositionMatrixTransform

Represents an arbitrary affine 2D transformation defined by a 3-by-2 matrix.

IDCompositionMatrixTransform3D

Represents an arbitrary 3D transformation defined by a 4-by-4 matrix.

IDCompositionRectangleClip

Represents a clip object that restricts the rendering of a visual subtree to the specified rectangular region. Optionally, the clip object may have rounded corners specified.

IDCompositionRotateTransform

Represents a 2D transformation that affects the rotation of a visual around the z-axis. The coordinate system is rotated around the specified center point.

IDCompositionSaturationEffect

This effect is used to alter the saturation of an image. The saturation effect is a specialization of the color matrix effect.

IDCompositionRotateTransform3D

Represents a 3D transformation that affects the rotation of a visual along an arbitrary axis in 3D space. The coordinate system is rotated around the specified center point.

IDCompositionScaleTransform

Represents a 2D transformation that affects the scale of a visual along the x-axis and y-axis. The coordinate system is scaled from the specified center point.

IDCompositionScaleTransform3D

Represents a 3D transformation effect that affects the scale of a visual along the x-axis, y-axis, and z-axis. The coordinate system is scaled from the specified center point.

IDCompositionSkewTransform

Represents a 2D transformation that affects the skew of a visual along the x-axis and y-axis. The coordinate system is skewed around the specified center point.

IDCompositionShadowEffect

The shadow effect is used to generate a shadow from the alpha channel of an image. The shadow is more 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.

IDCompositionSurface

Represents a physical bitmap that can be associated with a visual for composition in a visual tree. This interface can also be used to update the bitmap contents.

IDCompositionTableTransferEffect

The table transfer effect is used to map the color intensities of an image using a transfer function created from interpolating a list of values you provide.

IDCompositionSurfaceFactory

Creates surface and virtual surface objects associated with an application-provided rendering device.

IDCompositionTarget

Represents a binding between a DirectComposition visual tree and a destination on top of which the visual tree should be composed.

IDCompositionTransform

Represents a 2D transformation that can be used to modify the coordinate space of a visual subtree.

IDCompositionTransform3D

Represents a 3D transformation effect that can be used to modify the rasterization of a visual subtree.

IDCompositionTranslateTransform

Represents a 2D transformation that affects only the offset of a visual along the x-axis and y-axis.

IDCompositionTurbulenceEffect

The turbulence effect is used to generate a bitmap based on the Perlin noise function. The turbulence effect has no input image.

IDCompositionTranslateTransform3D

Represents a 3D transformation that affects the offset of a visual along the x-axis, y-axis, and z-axis.

IDCompositionVirtualSurface

Represents a sparsely allocated bitmap that can be associated with a visual for composition in a visual tree.

IDCompositionVisual

Represents a DirectComposition visual.

IDCompositionVisual2

Represents one DirectComposition visual in a visual tree.

IDCompositionVisualDebug

Represents a debug visual.
