Public Member Functions inherited from Graphic3d_TextureRoot
	~Graphic3d_TextureRoot ()
	Destructor.

virtual Standard_Boolean	IsDone () const
	Checks if a texture class is valid or not.

const OSD_Path &	Path () const
	Returns the full path of the defined texture. It could be empty path if GetImage() is overridden to load image not from file.

Graphic3d_TypeOfTexture	Type () const

const TCollection_AsciiString &	GetId () const
	This ID will be used to manage resource in graphic driver.

Standard_Size	Revision () const
	Return image revision.

void	UpdateRevision ()
	Update image revision. Can be used for signaling changes in the texture source (e.g. file update, pixmap update) without re-creating texture source itself (since unique id should be never modified).

virtual Handle< Image_CompressedPixMap >	GetCompressedImage (const Handle< Image_SupportedFormats > &theSupported)
	This method will be called by graphic driver each time when texture resource should be created. It is called in front of GetImage() for uploading compressed image formats natively supported by GPU.

virtual Handle< Image_PixMap >	GetImage (const Handle< Image_SupportedFormats > &theSupported)
	This method will be called by graphic driver each time when texture resource should be created. Default constructors allow defining the texture source as path to texture image or directly as pixmap. If the source is defined as path, then the image will be dynamically loaded when this method is called (and no copy will be preserved in this class instance). Inheritors may dynamically generate the image. Notice, image data should be in Bottom-Up order (see Image_PixMap::IsTopDown())!

	Returns a true value if this is an instance of TypeName.

Standard_Boolean	IsKind (const Standard_CString theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

Standard_Integer	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object.

Standard_Integer	DecrementRefCounter () noexcept
