  • 项目

Creates a texture resource from a stream object.

Definition

Visual Basic Public Shared Function FromStream( _
    ByVal device As Device, _
    ByVal data As StreamLeave Site, _
    ByVal usage As Usage, _
    ByVal pool As Pool _
) As Texture
C# public static Texture FromStream(
    Device device,
    StreamLeave Site data,
    Usage usage,
    Pool pool
);
C++ public:
static Texture^ FromStream(
    Device^ device,
    StreamLeave Site^ data,
    Usage usage,
    Pool pool
);
JScript public static function FromStream(
    device : Device,
    data : StreamLeave Site,
    usage : Usage,
    pool : Pool
) : Texture;

Parameters

device Microsoft.DirectX.Direct3D.Device
A Device object to associate with the Texture object.
data System.IO.Stream
A StreamLeave Site used to create the texture.
usage Microsoft.DirectX.Direct3D.Usage
Usage can be 0, which indicates no usage value. However, if usage is desired, use one or more Usage constants. It is good practice to match the usage parameter with the CreateFlags in the Device constructor.
pool Microsoft.DirectX.Direct3D.Pool
Member of the Pool enumerated type that describes the memory class into which the texture should be placed.

Return Value

Microsoft.DirectX.Direct3D.Texture
A Texture object.

Remarks

An application can discover support for automatic generation of mipmaps in a particular format by calling Manager.CheckDeviceFormat with Usage.AutoGenerateMipMap. If Manager.CheckDeviceFormat returns false, the Texture constructor succeeds, but returns a single-level texture.
