Interfaces

Direct2D provides the following interfaces.

In this section

TopicDescription

ID2D1AnalysisTransform

Supplies data to an analysis effect.

ID2D1Bitmap

Represents a bitmap that has been bound to an ID2D1RenderTarget.

ID2D1Bitmap1

Represents a bitmap that can be used as a surface for an ID2D1DeviceContext or mapped into system memory, and can contain additional color context information.

ID2D1BitmapBrush

Paints an area with a bitmap.

ID2D1BitmapBrush1

Paints an area with a bitmap.

ID2D1BitmapRenderTarget

Renders to an intermediate texture created by the CreateCompatibleRenderTarget method.

ID2D1BlendTransform

Provides methods to allow a blend operation to be inserted into a transform graph.

ID2D1BorderTransform

Extends the input rectangle to infinity using the specified extend modes.

ID2D1BoundsAdjustmentTransform

ID2D1Brush

Defines an object that paints an area. Interfaces that derive from ID2D1Brush describe how the area is painted.

ID2D1ColorContext

Represents a color context that can be used with an ID2D1Bitmap1 object.

ID2D1CommandList

Represents a sequence of commands that can be recorded and played back.

ID2D1CommandSink

The command sink is implemented by you for an application when you want to receive a playback of the commands recorded in a command list. A typical usage will be for transforming the command list into another format such as XPS when some degree of conversion between the Direct2D primitives and the target format is required.

The command sink interface doesn't have any resource creation methods on it. The resources are still logically bound to the Direct2D device on which the command list was created and will be passed in to the command sink implementation.

This interface performs all the same functions as the existing ID2D1CommandSink interface. It also enables access to the new primitive blend modes, MIN and ADD, through its SetPrimitiveBlend1 method.

ID2D1CommandSink2

This interface performs all the same functions as the existing ID2D1CommandSink1 interface. It also enables access to ink rendering and gradient mesh rendering.

ID2D1Device

Represents a resource domain whose objects and device contexts can be used together.

ID2D1Device1

Represents a resource domain whose objects and device contexts can be used together.

This interface performs all the same functions as the ID2D1DeviceContext1 interface, plus it enables functionality such as ink rendering, gradient mesh rendering, and improved image loading.

ID2D1GdiMetafile

A Direct2D resource that wraps a WMF, EMF, or EMF+ metafile.

ID2D1GdiMetafile1

This interface performs all the same functions as the existing ID2D1GdiMetafile interface. It also enables accessing the metafile DPI and bounds.

ID2D1GdiMetafileSink

A developer implemented interface that allows a metafile to be replayed.

ID2D1GdiMetafileSink1

This interface performs all the same functions as the existing ID2D1GdiMetafileSink interface. It also enables access to metafile records.
