SetWidthIndex (me: mutable; anIndex: Integer from Standard)
is static;
---Level: Public
---Purpose: Defines the index, in the width map, of the line width.
-- Warning: Note that the index 0 can be undefined as a WidthMapEntry,
-- in this case the default line width of 1 pixel is taken.

SetTypeIndex (me: mutable; anIndex: Integer from Standard)
is static;
---Level: Public
---Purpose: Defines the index, in the type map, of the line type.
-- Warning: Note that the index 0 can be undefined as a TypeMapEntry,
-- in this case the default line type SOLID is taken.
---Category: Methods to manage line attributes
SetInteriorColorIndex (me: mutable; anIndex: Integer from Standard)
is static;
---Level: Public
---Purpose: Defines the index, in the color map, of the interior
-- color.
-- Warning: The type of polygon filling must be :
-- Graphic2d_TOPF_FILLED
---Category: Methods to manage line attributes
SetDrawEdge (me: mutable; aDraw: Boolean from Standard)
is static;
---Level: Public
---Purpose: Defines if the edges are drawn or not.
-- Warning: The type of polygon filling must be :
