BeginString (me: mutable;
X,Y: Length from Quantity;
anOrientation: PlaneAngle from Quantity;
aWidth,aHeight: Length from Quantity;
aSlant: PlaneAngle from Quantity;
aPaintType: Integer from Standard) is redefined;
---Purpose: Calls when string drawing is started.
-- with a string aspect <aPaintType> :
-- 0 for filled string
-- 1 for stroke string
-- 2 for outline string
-- The origine of the string <X>,<Y>,
-- The orientation of the string <anOrientation>,
-- The medium size of the char <aWidth,aHeight>,
-- The Slant of the char <aSlant>,
BeginChar (me: mutable;
aCharCode: Integer from Standard;
X,Y: Length from Quantity)
returns Boolean from Standard is redefined;
---Purpose: Calls when a char drawing is started
-- and give the current string position for this char.
-- and give the relative char position from the beginning
-- of the string.
--The application can returns FALSE for skipping the char drawing.
SetCharBoundingBox (me: mutable;
X1,Y1,X2,Y2,X3,Y3,X4,Y4: Length from Quantity)
returns Boolean from Standard is redefined;
---Purpose: Calls to defines the current char bounding-box.
-- The application can returns FALSE for ending the char drawing.
SetCharEncoding (me: mutable;
anEncoding: CString from Standard)
returns Boolean from Standard is redefined;
---Purpose: Calls to defines the current char encoding.
-- Warning: The application can returns FALSE for skipping the char drawing.
Moveto (me: mutable; X,Y: Length from Quantity)
returns Boolean from Standard is redefined;
---Purpose: Calls to sets the current string position.
-- The application can returns FALSE for ending the char drawing.
Lineto (me: mutable; X,Y: Length from Quantity)
returns Boolean from Standard is redefined;
---Purpose: Calls to drawn to the current string position.
-- The application can returns FALSE for ending the char drawing.
Curveto (me: mutable; X1,Y1,X2,Y2,X3,Y3,X4,Y4: Length from Quantity)
returns Boolean from Standard is redefined;
---Purpose: Calls to drawn to the current string position.
-- The application can drawn the curve defined by
-- his descriptor P1,P2,P3,P4 or
-- returns FALSE to let the interpretor compute the curve
-- vectors.
ClosePath (me: mutable) is redefined;
---Purpose: Calls when a char path drawing is ended
EndChar (me: mutable; X,Y: Length from Quantity)
returns Boolean from Standard is redefined;
---Purpose: Calls when a char drawing is ended
-- and give the relative char ending position from the
-- beginning of the string.
-- The application can returns FALSE for skipping the string
-- drawing.
EndString (me: mutable ) is redefined;
---Purpose: Calls when string drawing is ended (Normally the last call).

SetTextAttribs (me: mutable;

---Purpose: Sets the current attribs of the text.
