    Graphic3d_LevelOfTextureAnisotropy AnisoFilter () const
    void SetAnisoFilter (const Graphic3d_LevelOfTextureAnisotropy theLevel)
    Public Member Functions inherited from Graphic3d_TextureRoot
     ~Graphic3d_TextureRoot () override
     Destructor.
    virtual bool IsDone () const
     Checks if a texture class is valid or not.
    const OSD_PathPath () 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_AsciiStringGetId () const
     This ID will be used to manage resource in graphic driver.
    size_t 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 occ::handle< Image_CompressedPixMapGetCompressedImage (const occ::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 occ::handle< Image_PixMapGetImage (const occ::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())!
    const occ::handle< Graphic3d_TextureParams > & GetParams () const
    bool IsColorMap () const
     Return flag indicating color nature of values within the texture; TRUE by default.

     Returns whether row's memory layout is top-down.
    Public Member Functions inherited from Standard_Transient
     Standard_Transient ()
     Empty constructor.
     Standard_Transient (const Standard_Transient &)
     Copy constructor – does nothing.
    Standard_Transientoperator= (const Standard_Transient &)
     Assignment operator, needed to avoid copying reference counter.
    virtual ~Standard_Transient ()=default
     Destructor must be virtual.
    virtual const opencascade::handle< Standard_Type > & DynamicType () const
     Returns a type descriptor about this object.
    bool IsInstance (const opencascade::handle< Standard_Type > &theType) const
     Returns a true value if this is an instance of Type.
    bool IsInstance (const char *const theTypeName) const
     Returns a true value if this is an instance of TypeName.
    bool IsKind (const opencascade::handle< Standard_Type > &theType) const
     Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
    bool IsKind (const char *const 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_TransientThis () 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.
    int GetRefCount () const noexcept
     Get the reference counter of this object.
    void IncrementRefCounter () noexcept
     Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
    int DecrementRefCounter () noexcept
     Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
    virtual void Delete () const
     Memory deallocator for transient classes.
