  • Method Details

    • getDashArray

      public PdfArray getDashArray()
      Getter for the dash array. The dash array’s elements is number that specify the lengths of alternating dashes and gaps; the numbers are nonnegative. The elements are expressed in user space units.
      Returns:
      The dash array.
    • setDashArray

      public void setDashArray(PdfArray dashArray)
      Setter for the dash array. See getDashArray()
      Parameters:
      dashArray - New dash array.
    • getDashPhase

      public float getDashPhase()
      Getter for the dash phase. The dash phase shall specify the distance into the dash pattern at which to start the dash. The elements are expressed in user space units.
      Returns:
      The dash phase.
    • setDashPhase

      public void setDashPhase(float dashPhase)
      Setter for the dash phase. See getDashArray()
      Parameters:
      dashPhase - New dash phase.
    • next

      Calculates and returns the next element which is either gap or dash.

    • isSolid

      public boolean isSolid()
      Checks whether the dashed pattern is solid or not. It's solid when the size of a dash array is even and sum of all the units off in the array is 0.
      For example: [3 0 4 0 5 0 6 0] (sum is 0), [3 0 4 0 5 1] (sum is 1).
