  • Article

Adds a dirty region to a cube texture resource.

Definition

Visual Basic Public Sub AddDirtyRectangle( _
    ByVal faceType As CubeMapFace, _
    ByVal rect As RectangleLeave Site _
)
C# public void AddDirtyRectangle(
    CubeMapFace faceType,
    RectangleLeave Site rect
);
C++ public:
void AddDirtyRectangle(
    CubeMapFace faceType,
    RectangleLeave Site rect
);
JScript public function AddDirtyRectangle(
    faceType : CubeMapFace,
    rect : RectangleLeave Site
);

Parameters

faceType Microsoft.DirectX.Direct3D.CubeMapFace
A CubeMapFace value that identifies the face where the dirty region will be added. Omitting the sig_CubeMapFace_Rectangle parameter indicates that the dirty region should expand to cover the full face.
rect System.Drawing.Rectangle
A RectangleLeave Site that specifies the dirty region.

Remarks

For performance reasons, dirty regions are recorded only for level 0 of a texture. For sublevels, it is assumed that the corresponding (scaled) rectangle or box is also dirty. Dirty regions are automatically recorded when CubeTexture.LockRectangle is called without LockFlags.NoDirtyUpdate or LockFlags.ReadOnly.

Exceptions

InvalidCallException

The method call is invalid. For example, a method's parameter might contain an invalid value.
