---Copyright:
--
package IGESGraph
---Purpose : This package contains the group of classes necessary
-- to define Graphic data among Structure Entities.
-- (e.g., Fonts, Colors, Screen management ...)
uses
Standard,
TCollection,
gp,
TColgp,
TColStd,
Message,
Interface,
IGESData,
IGESBasic
is
class LineFontDefTemplate;
-- type <304> form <1>
---Purpose : Line Font Def can be defined as a repetition of Template
-- figure that is displayed at regularly spaced locations
-- along a planar anchoring curve. The anchoring curve
-- itself has no visual purpose.
class LineFontDefPattern;
-- type <304> form <2>
---Purpose : Line Font Def may be defined by repetition of a basic
-- pattern of visible-blank(or, on-off) segments
-- superimposed on a line or a curve. The line or curve
-- is then displayed according to the basic pattern.
class TextFontDef;
-- type <310>
---Purpose : Used to define the appearance of characters in a text
-- font. It may be used to describe a complete font or a
-- modification to a subset of characters in another font.
class TextDisplayTemplate;
-- type <312> form <0, 1>
---Purpose : Used to set parameters for display of information
-- which has been logically included in another entity
-- as a parameter value.
class Color;
-- type <314>
---Purpose : The Color Definition Entity is used to communicate the
-- relationship of primary colors to the intensity level of
-- the respective graphics devices as a percent of full
-- intensity range.
class DefinitionLevel;
-- type <406> form <1>
---Purpose : Indicates the no. of levels on which an entity is
-- defined.
class NominalSize;
-- type <406> form <13>
---Purpose : Specifies a value, a name, and optionally a
-- reference to an engineering standard.
class DrawingSize;
-- type <406> form <16>
---Purpose : Specifies the drawing size in drawing units. The
-- origin of the drawing is defined to be (0,0) in
-- drawing space.
class DrawingUnits;
-- type <406> form <17>
---Purpose : Specifies the drawing space units as outlined
-- in the Drawing entity.
class IntercharacterSpacing;
-- type <406> form <18>
---Purpose : Specifies the gap between letters when fixed-pitch
-- spacing is used.
class LineFontPredefined;
-- type <406> form <19>
---Purpose : Provides the ability to specify a line font pattern
-- from a predefined list rather than from
-- Directory Entry Field 4.
class HighLight;
-- type <406> form <20>
---Purpose : Attaches information that an entity is to be
-- displayed in some system dependent manner.
class Pick;
-- type <406> form <21>
---Purpose : Attaches information that an entity may be picked
-- by whatever pick device is used in the receiving
-- system.
class UniformRectGrid;
-- type <406> form <22>
---Purpose : Stores sufficient information for the creation of
-- a uniform rectangular grid within a drawing.
-- Tools for Entities --
class ToolLineFontDefTemplate;
class ToolLineFontDefPattern;
class ToolTextFontDef;
class ToolTextDisplayTemplate;
class ToolColor;
class ToolDefinitionLevel;
class ToolNominalSize;
class ToolDrawingSize;
class ToolDrawingUnits;
class ToolIntercharacterSpacing;
class ToolLineFontPredefined;
class ToolHighLight;
class ToolPick;
class ToolUniformRectGrid;
-- Definition and Exploitation of Entities defined in this Package
class Protocol;
class ReadWriteModule;
class GeneralModule;
class SpecificModule;
-- The class instantiations :
class Array1OfColor instantiates Array1 from TCollection (Color);
class Array1OfTextDisplayTemplate instantiates
Array1 from TCollection (TextDisplayTemplate);
class Array1OfTextFontDef instantiates
Array1 from TCollection (TextFontDef);
class HArray1OfColor instantiates HArray1 from TCollection
(Color,Array1OfColor);
class HArray1OfTextDisplayTemplate instantiates HArray1 from TCollection
(TextDisplayTemplate,Array1OfTextDisplayTemplate);
class HArray1OfTextFontDef instantiates HArray1 from TCollection
(TextFontDef,Array1OfTextFontDef);
-- Package Methods
Init;
---Purpose : Prepares dynamic data (Protocol, Modules) for this package
Protocol returns Protocol from IGESGraph;
---Purpose : Returns the Protocol for this Package
end IGESGraph;
