Creates a render target surface.

Namespace: Microsoft.WindowsMobile.DirectX.Direct3D
Assembly: Microsoft.WindowsMobile.DirectX (in Microsoft.WindowsMobile.DirectX.dll)

Syntax

'Declaration
Public Function CreateRenderTarget ( _
    width As Integer, _
    height As Integer, _
    format As Format, _
    multiSampleType As MultiSampleType, _
    lockable As Boolean _
) As Surface
'Usage
Dim instance As Device
Dim width As Integer
Dim height As Integer
Dim format As Format
Dim multiSampleType As MultiSampleType
Dim lockable As Boolean
Dim returnValue As Surface

returnValue = instance.CreateRenderTarget(width, _
    height, format, multiSampleType, _
    lockable)

public Surface CreateRenderTarget(
    int width,
    int height,
    Format format,
    MultiSampleType multiSampleType,
    bool lockable
)

public:
Surface^ CreateRenderTarget(
    int width, 
    int height, 
    Format format, 
    MultiSampleType multiSampleType, 
    bool lockable
)

member CreateRenderTarget : 
        width:int * 
        height:int * 
        format:Format * 
        multiSampleType:MultiSampleType * 
        lockable:bool -> Surface

Parameters

width
Type: System.Int32
The width of the render-target surface, in pixels.

height
Type: System.Int32
The height of the render-target surface, in pixels.

format
Type: Microsoft.WindowsMobile.DirectX.Direct3D.Format
A member of the Format enumerated type that describes the format of the render target.

multiSampleType
Type: Microsoft.WindowsMobile.DirectX.Direct3D.MultiSampleType
A member of the MultiSampleType enumerated type that describes the multisampling buffer type. This parameter specifies the anti-aliasing type for the render target. When this surface is passed to SetRenderTarget, its multisample type must be the same as that of the depth stencil property DepthStencilSurface.

lockable
Type: System.Boolean
Set to true if render targets are lockable; otherwise, false. Note that lockable render targets reduce performance on some graphics hardware.

Return Value

Type: Microsoft.WindowsMobile.DirectX.Direct3D.Surface
A Surface.

Exceptions

Exception	Condition
NotAvailableException	The device does not support the queried multisample type.
InvalidCallException	The method call is invalid. For example, a parameter might contain an invalid value.
OutOfMemoryException	Direct3D has insufficient memory to complete the call.

Remarks

A render target surface is a rendering surface. For example, a 3-D renderer writes per-pixel scene data, such as color, to a render target surface.

Render-target surfaces are placed in the Pool memory class. The creation of lockable, multisampled render targets is not supported.
