D3DX8.CheckTextureRequirements

Checks texture creation parameters.

object.CheckTextureRequirements( _ 
    Device As Direct3DDevice8, _ 
    Width As Long, _ 
    Height As Long, _ 
    NumMipLevels As Long, _ 
    Usage As Long, _ 
    Format As CONST_D3DFORMAT, _ 
    Pool As CONST_D3DPOOL)

Parts

object: Object expression that resolves to a D3DX8 object.
Device: Direct3DDevice8 object representing the device associated with the cube texture.
Width: Requested width in pixels, or ByVal 0. Returns the corrected size.
Height: Requested height in pixels, or ByVal 0. Returns the corrected size.
NumMipLevels: Number of requested mipmap levels, or ByVal 0. Returns the corrected number of mipmap levels.
Usage: 0 or the D3DUSAGE_RENDERTARGET member of the CONST_D3DUSAGEFLAGS enumeration. Specifying D3DUSAGE_RENDERTARGET indicates that the surface is to be used as a render target. The resource can be passed to the NewRenderTarget parameter of the SetRenderTarget method. If D3DUSAGE_RENDERTARGET is specified, the application should check that the device supports this operation by calling Direct3D8.CheckDeviceFormat.
Format: Member of the CONST_D3DFORMAT enumeration. Specifies the desired pixel format. Returns the corrected format.
Pool: Member of the CONST_D3DPOOL enumeration, describing the memory class into which the texture should be placed.
