42 | -- Specific Methods pertaining to the class |
43 | |
44 | Init (me : mutable; |
45 | leftCorner : XYZ; |
46 | anAngle : Real; |
47 | aNote : GeneralNote; |
48 | someLeaders : HArray1OfLeaderArrow); |
49 | ---Purpose : This method is used to set the fields of the class |
50 | -- FlagNote |
51 | -- - leftCorner : Lower left corner of the Flag |
52 | -- - anAngle : Rotation angle in radians |
53 | -- - aNote : General Note Entity |
54 | -- - someLeaders : Leader Entities |
55 | |
56 | LowerLeftCorner (me) returns Pnt; |
57 | ---Purpose : returns Lower Left coordinate of Flag as Pnt from package gp |
58 | |
59 | TransformedLowerLeftCorner (me) returns Pnt; |
60 | ---Purpose : returns Lower Left coordinate of Flag as Pnt from package gp |
61 | -- after Transformation. |
62 | |
63 | Angle (me) returns Real; |
64 | ---Purpose : returns Rotation angle in radians |
65 | |
66 | Note (me) returns GeneralNote; |
67 | ---Purpose : returns General Note Entity |

77 | -- The below provided methods do not have corresponding fields. |
78 | -- They are provided as mentioned in the IGES specs. |
79 | |
80 | Height (me) returns Real; |
81 | ---Purpose : returns Height computed by the formula : |
82 | -- Height = 2 * CH where CH is from theNote |

85 | ---Purpose : returns the Character Height (from General Note) |
86 | |
87 | Length (me) returns Real; |
88 | ---Purpose : returns Length computed by the formula : |
89 | -- Length = TW + 0.4*CH where CH is from theNote |
90 | -- and TW is from theNote |
91 | |
92 | TextWidth (me) returns Real; |
93 | ---Purpose : returns the Text Width (from General Note) |
94 | |
95 | TipLength (me) returns Real; |
96 | ---Purpose : returns TipLength computed by the formula : |
97 | -- TipLength = 0.5 * H / tan 35(deg) where H is Height() |
