Loads a volume from a file.

Definition

Visual Basic Public Shared Sub FromFile( _
    ByVal destVolume As Volume, _
    ByVal srcFile As String, _
    ByVal filter As Filter, _
    ByVal colorKey As Integer _
)
C# public static void FromFile(
    Volume destVolume,
    string srcFile,
    Filter filter,
    int colorKey
);
C++ public:
static void FromFile(
    VolumedestVolume,
    StringLeave SitesrcFile,
    Filter filter,
    int colorKey
);
JScript public static function FromFile(
    destVolume : Volume,
    srcFile : String,
    filter : Filter,
    colorKey : int
);

Parameters

destVolume Microsoft.DirectX.Direct3D.Volume
A Volume object that specifies the destination volume.
srcFile System.String
String that specifies the file name.
filter Microsoft.DirectX.Direct3D.Filter
One or more Filter flags that control how the image is filtered.
colorKey System.Int32
An Int32Leave Site value to replace with transparent black, or 0 to disable the color key. This is always a 32-bit ARGB color that is independent of the source image format. Alpha is significant, and usually should be set to FF for opaque color keys. For example, for opaque black, the value is equal to 0xFF000000.

Remarks

This method supports the following file formats: .bmp, .dds, .dib, .hdr, .jpg, .pfm, .png, .ppm, and .tga. It handles conversion to and from compressed texture formats.

Writing to any surface except the "zero" level surface of the volume texture does not cause the dirty rectangle to be updated. If FromFile is called and the texture is not already dirty (which is unlikely under normal usage scenarios), the application must explicitly call VolumeTexture.AddDirtyBox on the volume texture.

Exceptions
