Package org.apache.poi.sl.draw.geom

Class ArcToCommand

java.lang.Object
org.apache.poi.sl.draw.geom.ArcToCommand
All Implemented Interfaces:
ArcToCommandIf, PathCommand
public class ArcToCommand extends 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
