IDirect3DDevice8::CreateTexture

  • Article

This method creates a texture resource.

HRESULT CreateTexture(
  UINT Width,
  UINT Height,
  UINT Levels,
  DWORD Usage,
  D3DFORMAT Format,
  D3DPOOL Pool,
  IDirect3DTexture8** ppTexture
);

Parameters

  • Width
    [in] Width of the top-level of the texture, in pixels. The pixel dimensions of subsequent levels will be the truncated value of half of the previous level's pixel dimension (independently). Each dimension clamps at a size of 1 pixel. Thus, if the division by 2 results in 0 (zero), 1 will be taken instead.

  • Height
    [in] Height of the top-level of the texture, in pixels. The pixel dimensions of subsequent levels will be the truncated value of half of the previous level's pixel dimension (independently). Each dimension clamps at a size of 1 pixel. Thus, if the division by 2 results in 0 (zero), 1 will be taken instead.

  • Levels
    [in] The number of levels in the texture. If this is zero, Microsoft® Direct3D® will generate all texture sublevels down to 1×1 pixels for hardware that supports MIP mapped textures. Otherwise, it will create one level. Call IDirect3DBaseTexture8::GetLevelCount to see the number of levels generated.

  • Usage
    [in] Combination of one or more of the following flags, describing the usage for this resource.

    Flag Description
    D3DUSAGE_DEPTHSTENCIL Set to indicate that the surface is to be used as a depth-stencil surface. The resource can be passed to the pNewZStencil parameter of the IDirect3DDevice8::SetRenderTarget method.
    D3DUSAGE_RENDERTARGET Set to indicate that the surface is to be used as a render target. The resource can be passed to the pRenderTarget parameter of SetRenderTarget.

    If either D3DUSAGE_RENDERTARGET or D3DUSAGE_DEPTHSTENCIL is specified, the application should check that the device supports these operations by calling IDirect3D8::CheckDeviceFormat.

  • Format
    [in] Member of the D3DFORMAT enumerated type, describing the format of all levels in the texture.

  • Pool
    [in] Member of the D3DPOOL enumerated type, describing the memory class into which the texture should be placed.

  • ppTexture
    [out, retval] Address of a pointer to an IDirect3DTexture8 interface, representing the created texture resource.

Return Values

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be one of the following values:

Remarks

In order to call IDirect3DDevice8::SetRenderTarget with a texture, you must select a level using IDirect3DTexture8::GetSurfaceLevel and pass the resulting surface to SetRenderTarget.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: D3d8.h.
Link Library: D3d8.lib.
