Class ArcToCommand

java.lang.Object

org.apache.poi.sl.draw.geom.ArcToCommand

All Implemented Interfaces:

ArcToCommandIf, PathCommand

public class ArcToCommand
extends java.lang.Object
implements ArcToCommandIf

ArcTo command within a shape path in DrawingML: <arcTo wR="wr" hR="hr" stAng="stAng" swAng="swAng"/>

Where wr and wh are the height and width radii of the supposed circle being used to draw the arc. This gives the circle a total height of (2 * hR) and a total width of (2 * wR)

stAng is the start angle and swAng is the swing angle

convertOoxml2AwtAngle

@Internal
public static double convertOoxml2AwtAngle(double ooAngle,
                                                     double width,
                                                     double height)

Arc2D angles are skewed, OOXML aren't ... so we need to unskew them

Furthermore, ooxml angle starts at the X-axis and increases clock-wise, whereas Arc2D api states "45 degrees always falls on the line from the center of the ellipse to the upper right corner of the framing rectangle" so we need to reverse it

 AWT:                      OOXML:
            |90/-270                     |270/-90 (16200000)
            |                            |
 +/-180-----------0           +/-180-----------0
            |               (10800000)   |
            |270/-90                     |90/-270 (5400000)
 

Parameters:

ooAngle - the angle in OOXML units divided by 60000

width - the width of the bounding box

height - the height of the bounding box

Returns:

the angle in degrees
