• setSplitAtPage

  public void setSplitAtPage(int split)

  This will tell the splitting algorithm where to split the pages. The default is 1, so every page will become a new document. If it was two then each document would contain 2 pages. If the source document had 5 pages it would split into 3 new documents, 2 documents containing 2 pages and 1 document containing one page.

  Parameters:

  split - The number of pages each split document should contain.

• splitAtPage

  protected boolean splitAtPage(int pageNumber)

  Parameters:

  pageNumber - the page number to be checked as splitting page

  Returns:

  true If a new document should be created.
