class LineFontDefTemplate from IGESGraph inherits LineFontEntity
---Purpose : defines IGESLineFontDefTemplate, Type <304> Form <1>
-- in package IGESGraph
--
-- Line Font can be defined as a repetition od Template figure
-- that is displayed at regularly spaced locations along a
-- planer anchoring curve. The anchoring curve itself has
-- no visual purpose.
uses
IGESEntity from IGESData,
SubfigureDef from IGESBasic
is
Create returns mutable LineFontDefTemplate;
-- Specific Methods pertaining to class
Init (me : mutable;
anOrientation : Integer;
aTemplate : SubfigureDef;
aDistance : Real;
aScale : Real);
---Purpose : This method is used to set the fields of the class
-- LineFontDefTemplate
-- - anOrientation : Orientation of Template figure on
-- anchoring curve
-- - aTemplate : SubfigureDef entity used as Template figure
-- - aDistance : Distance between the neighbouring Template
-- figures
-- - aScale : Scale factor applied to the Template figure
Orientation (me) returns Integer;
---Purpose : if return value = 0, Each Template display is oriented by aligning
-- the axis of the SubfigureDef with the axis of
-- the definition space of the anchoring curve.
-- = 1, Each Template display is oriented by aligning
-- X-axis of the SubfigureDef with the tangent
-- vector of the anchoring curve at the point of
-- incidence of the curve and the origin of
-- subfigure.
-- Similarly Z-axis is aligned.
TemplateEntity (me) returns SubfigureDef;
---Purpose : returns SubfigureDef as the Entity used as Template figure.
Distance (me) returns Real;
---Purpose : returns the Distance between any two Template figures on the
-- anchoring curve.
Scale (me) returns Real;
---Purpose : returns the Scaling factor applied to SubfigureDef to form
-- Template figure.

-- Class : IGESGraph_LineFontDefTemplate
--
-- Purpose : Declaration of the variables specific to Line Font Templates.
--
-- Reminder : A Line Font Template is defined by :
-- - Orientation of Template figure on the anchoring curve
-- - Sub Figure definition entity used as Template figure
-- - Distance between the neighbouring Template figures
-- - Scale factor applied to the Template figure
