    • setFoundParagraphAsArray

      public int[] setFoundParagraphAsArray(int x, int y, int page)
      Highlights a section of lines that form a paragraph and returns the area that encloses all highlight localAreas.
      Parameters:
      x - Coord x value to begin looking for a paragraph
      y - Coord y value to begin looking for a paragraph
      page - Page number of page to look for a paragraph on
      Returns:
      int[] that contains x,y,w,h of all localAreas highlighted

    • addToLineAreas

      public void addToLineAreas(int[] area, int writingMode, int page)

    • clearHighlights

      public void clearHighlights()
      Clear all highlights that are being displayed

    • addHighlights

      public void addHighlights(int[][] highlights, boolean areaSelect, int page)
      Method to highlight text on page.

      If areaSelect = true then the Rectangle array will be highlgihted on screen unmodified. areaSelect should be true when being used with values returned from the search as these localAreas are already corrected and modified for display.

      If areaSelect = false then all lines between the top left point and bottom right point will be selected including two partial lines the top line starting from the top left point of the rectangle and the bottom line ending at the bottom right point of the rectangle.

      Parameters:
      highlights - :: The 2DArray contains the raw x,y,w,h params of a set of rectangles that you wish to have highlighted
      areaSelect - :: The flag that will either select text as line between points if false or characters within an area if true.
      page - :: The page to add highlights to.
