  • Method Details

    • getPageCount

      int getPageCount()
      Get the current count of pages.
      Returns:
      the page count
      Since:
      16.2
    • clear

      void clear()
      Reset this output in the initial state. So getPageCount() == 0 and getFontCount() == 0.

      @Nonnull byte[] getPageData(int idx) throws ArrayIndexOutOfBoundsException
      Get the binary data of a page/chunk.
      Parameters:
      idx - the index, starts with 1
      Returns:
      the data, never null
      Throws:
      ArrayIndexOutOfBoundsException - if index is out of range
      Since:
      16.2
    • getGroupTree

      byte[] getGroupTree()
      Get the data of the group tree.
      Returns:
      Can be null, if not set.
      Since:
      16.2
    • addPage

      void addPage(@Nonnull byte[] page) throws IllegalStateException
      Add a page/chunk. Increment getPageCount()
      Parameters:
      page - the binary data, never null
      Throws:
      IllegalStateException - if this output is finish or stopped.
      Since:
      16.2
    • setPageData

      void setPageData(@Nonnull byte[] page, int idx) throws IllegalStateException
      Override/patched an existing page/chunk.
