Usage: you must use this class as is. You should never derive it.
public class CAT2DArrowSymbolGP
Class to create a dynamic graphic primitive of a 2D arrow symbol.
Constructor and Destructor Index
- o
CAT2DArrowSymbolGP()
- Constructs a default graphic primitive of a two dimensional arrow symbol.
- o
CAT2DArrowSymbolGP(float[2],float[2],float,float,CATSymbolType,int)
- Constructs a 2D arrow symbol Graphic primitive.
Method Index
- o
Get(float**,float**,float*,float*,CATSymbolType*,int*)

Constructor and Destructor
o CAT2DArrowSymbolGP
| public CAT2DArrowSymbolGP( | ) |
-
Constructs a default graphic primitive of a two dimensional arrow symbol.
o CAT2DArrowSymbolGP
| public CAT2DArrowSymbolGP( | const | iPoint, |
| const | iDirection, |
| const | iSize_in_mm, |
| const | iAngle, |
| | iSymbol, |
| const | iZoom | = 0) |
-
Constructs a 2D arrow symbol Graphic primitive.
- Parameters:
-
- iPoint
- the position of the 2D arrow symbol.
This is the point which represents the top of the 2D arrow symbol.
- iDirection
- the direction vector of the 2D arrow symbol.
The direction vector is assumed to be normalized
- iSize_in_mm
- the size of the 2D arrow symbol among the axis defined by the Direction vector.
- iAngle
- the angle (in radians) formed by the line going from
iPoint and directed by iDirection, and one of the slanted arrowhead
lines.
It determines how wide the arrowhead is at the base.
- iSymbol
- the type of 2D arrow symbol.
legal values:
OPEN_ARROW :
arrow drawn with two symetric segments
with respect to the vector director
UNFILLED_ARROW :
unfilled arrow drawn with three segments.
FILLED ARROW :
filled arrow drawn with three segments.
BLANKER_ARROW :
arrow drawn with three segments.
This arrow is composed of two arrows: one
is an UNFILLED_ARROW 2D arrow and the other one is
a FILLED_ARROW 2D arrow which has the color of the background.
- iZoom
- the type of size values.
legal values:
0 :
size is expressed in millimeter.
1 :
size is expressed in model unit.
