Detailed Description

manage a DirectX ID3DTexture/IDirect3DTexture9. (may be file or created internally) A texture can be made of 1 or many MIP Mapped surfaces. cSurfaceBase Can be associated with a model or a sprite set.

DeleteDeviceObjects()

HRESULT Gray3D::cDXTextureBase::DeleteDeviceObjects ( )

virtual

Must release this.

Reimplemented from Gray3D::cDXBase.

Reimplemented in Gray3D::cXTextureFile, and Gray3D::cDXTexture.

get_DXTexture()

get_OrigSize()

get_OrigSizeX()

get_OrigSizeY()

PIXELS_t Gray3D::cDXTextureBase::get_OrigSizeY ( ) const

GetDescSize()

bool Gray3D::cDXTextureBase::GetDescSize

(

SIZE *

pSize

The allocated size.

Get the allocated size m_SizeDesc.

Note

This may be a change to a power of 2 ?

IsFullOpaque()

bool Gray3D::cDXTextureBase::IsFullOpaque ( ) const

inlinenoexcept

isLoaded()

bool Gray3D::cDXTextureBase::isLoaded ( ) const

inlinenoexcept

STDMETHOD_()

Gray3D::cDXTextureBase::STDMETHOD_ ( cString  , get_Name    ) const

pure virtual

Implemented in Gray3D::cDXTexture, and Gray3D::cXTextureFile.

UpdateDescSize()

HRESULT Gray3D::cDXTextureBase::UpdateDescSize

(

)

Filtering may change the actual size loaded from m_SizeOrig. ASSUME InitDeviceObjects calls this.

UpdateFullOpaqueHint()

HRESULT Gray3D::cDXTextureBase::UpdateFullOpaqueHint ( )

protected

compute m_IsFullOpaque. its not so costly as it looks, since we've loaded/filtered whole texture already

UpdateOrigSize()

virtual bool Gray3D::cDXTextureBase::UpdateOrigSize ( )

inlinevirtual

We can sometimes read the size before actually loading the image file.

Reimplemented in Gray3D::cXTextureFile.
