deferred  class  Texture2D  from  Graphic3d 
    
inherits  TextureMap  from  Graphic3d  

    ---Purpose: This abstract class for managing 2D textures

uses  
    TypeOfTexture  from  Graphic3d,
    NameOfTexture2D  from  Graphic3d, 
    StructureManager from  Graphic3d 

    
raises
    OutOfRange from Standard
 
is 
    Initialize(SM  :  StructureManager  from  Graphic3d;
    	       aFileName  :  CString  from  Standard; 
    	       aType      :  TypeOfTexture  from  Graphic3d);
	        
    Initialize(SM  :  StructureManager  from  Graphic3d; 
	       aName  :  NameOfTexture2D  from  Graphic3d;
    	       aType :  TypeOfTexture  from  Graphic3d); 

    Name(me) returns NameOfTexture2D from Graphic3d;
    ---Purpose:
    -- Returns the name of the predefined textures or NOT_2D_UNKNOWN
    -- when the name is given as a filename.
    ---Level: Public

    NumberOfTextures(myclass) returns Integer from Standard;
    ---Purpose:
    -- Returns the number of predefined textures.
    ---Level: Public

    TextureName(myclass; aRank: Integer from Standard)
        returns CString from Standard
        raises OutOfRange from Standard;
    ---Purpose:
    -- Returns the name of the predefined texture of rank <aRank>
    ---Trigger: when <aRank> is < 1 or > NumberOfTextures.
    ---Level: Public
