The IDXSurfaceFactory interface provides methods to create and load data into DXSurface data objects.
Members
The IDXSurfaceFactory interface inherits from the IUnknown interface. IDXSurfaceFactory also has these types of members:
- Methods
Methods
The IDXSurfaceFactory interface has these methods.
| Method | Description |
|---|---|
| BitBlt | Copies samples from one DXSurface to another. |
| CopySurfaceToNewFormat | Copies one surface to another and changes its pixel format. |
| CreateD3DRMTexture | |
| CreateFromDDSurface | Creates a DXSurface that contains a specified DirectDrawSurface object. |
| CreateSurface | Creates a DXSurface object of the specified size and format. |
| LoadImage | Binds the specified file name or URL and returns a DXSurface containing the image data. |
| LoadImageFromStream | Loads an image from a stream and returns a DXSurface. |
Remarks
The most commonly used method of this interface is IDXSurfaceFactory::CreateSurface, which creates an uninitialized DXSurface of a specified size and pixel format. The IDXSurfaceFactory::LoadImage method is also useful. This method translates an image from a common image format, such as .gif, .jpg, and .bmp, and stores the result in a new DXSurface.
This interface is exposed by the IDXTransformFactory interface. The recommended way to expose the interface is by using the IServiceProvider::QueryService method on the IDXTransformFactory with SID_DXSurfaceFactory as the service ID. You can create procedural surfaces by specifying the class identifier (CLSID) of the procedural surface for the pFormatID parameter and by using the IDXSurfaceFactory::CreateSurface method.
