getPrimaryDirection
Get the primary writing direction of the word list.
getPrimaryDirection([out, retval] int *dir)
This function returns the primary writing direction of the word list
constructed by the most recent call to
buildWordList. The result
will be +1 for left-to-right scripts, and -1 for right-to-left
scripts. The primary writing direction is determined by counting the
number of left-to-right and right-to-left characters, and choosing the
larger count.
To get the writing direction of individual words, call
getWordDirection.
VB:
Dim word As Long

primaryDir = pdf.getPrimaryDirection()
For i = 0 To pdf.getNumWords() - 1
word = pdf.getWord(i)
