Parameters

device Microsoft.DirectX.Direct3D.Device
A Device object that represents the device to associate with the volume texture.

stream System.IO.Stream
A Stream from which to create the texture.

readBytes System.Int32
Size, in bytes, of the file in memory.

width System.Int32
Width in pixels. If this value is 0, the dimensions are taken from the file. The maximum dimension that a driver supports (for width, height, and depth) can be found in the Caps.MaxVolumeExtent property.

height System.Int32
Height in pixels. If this value is 0, the dimensions are taken from the file. The maximum dimension that a driver supports (for width, height, and depth) can be found in the Caps.MaxVolumeExtent property.

depth System.Int32
Depth in pixels. If this value is 0, the dimensions are taken from the file. The maximum dimension that a driver supports (for width, height, and depth) can be found in the Caps.MaxVolumeExtent property.

mipLevels System.Int32
Number of mip levels requested. If this value is 0, a complete mipmap chain is created.

usage Microsoft.DirectX.Direct3D.Usage
Zero or Usage.RenderTarget, or Usage.Dynamic. Setting this flag to Usage.RenderTarget indicates that the surface will be used as a render target. The resource can then be passed to the param_Surface_renderTarget parameter of the Device.SetRenderTarget method. If Usage.RenderTarget is specified, the application should determine whether the device supports this operation by calling Manager.CheckDeviceFormat. The Usage.Dynamic value indicates that the surface should be handled dynamically.

format Microsoft.DirectX.Direct3D.Format
Member of the Format enumerated type that describes the requested pixel format for the cube texture. The returned cube texture might have a different format from that specified by param_Format_format. Applications should check the format of the returned cube texture. If param_Format_format is Unknown, the format is taken from the file.

pool Microsoft.DirectX.Direct3D.Pool
Member of the Pool enumerated type that describes the memory class into which the cube texture should be placed.

filter Microsoft.DirectX.Direct3D.Filter
One or more Filter flags that control how the image is filtered.

mipFilter Microsoft.DirectX.Direct3D.Filter
One or more Filter flags that control how the mipmaps are filtered.

colorKey System.Int32
An Int32 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.

Return Value

Microsoft.DirectX.Direct3D.VolumeTexture
Address of a pointer to a VolumeTexture object that represents the created texture object.

Remarks

This method supports the following file formats: .bmp, .dds, .dib, .hdr, .jpg, .pfm, .png, .ppm, and .tga.

Exceptions
