VolumeLoader.FromStream Method

Language:

Creates a volume from a file in memory.

Definition

Visual Basic Public Shared Sub FromStream( _
    ByVal destVolume As Volume, _
    ByVal stream As Stream, _
    ByVal readBytes As Integer, _
    ByVal filter As Filter, _
    ByVal colorKey As Integer _
)
C# public static void FromStream(
    Volume destVolume,
    Stream stream,
    int readBytes,
    Filter filter,
    int colorKey
);
C++ public:
static void FromStream(
    VolumedestVolume,
    Streamstream,
    int readBytes,
    Filter filter,
    int colorKey
);
JScript public static function FromStream(
    destVolume : Volume,
    stream : Stream,
    readBytes : int,
    filter : Filter,
    colorKey : int
);

Parameters

destVolume Microsoft.DirectX.Direct3D.Volume
A Volume object that specifies the destination volume.
stream System.IO.Stream
A Stream Leave Site that contains the source volume texture in memory.
readBytes System.Int32
Size of the file in memory, in bytes.
filter Microsoft.DirectX.Direct3D.Filter
One or more Filter flags that control how the image is filtered.
colorKey System.Int32
An Int32 Leave 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 a non-level-zero 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
InvalidCallException The method call is invalid. For example, a method's parameter might contain an invalid value.
InvalidDataException The data is invalid.
