Electronic Leading

       Methods for specifying the formatting characteristics of
a document, and electronically encoding these specifications with the
document content are well known.  A method is provided here for
specifying and encoding the formatting characteristics for the
vertical 'leading.'

      Vertical leading refers to the amount of space inserted between
lines of text.  The technique is used to align the first and last
line of text on facing pages, or providing a balanced visual
appearance of blocks (paragraphs) of text on a page.  The term
'leading' refers to a technique used by manual typesetters where lead
spacers are inserted between lines or blocks of type set text.  The
places where leading is to be inserted are called lead-out points.

      The current method uses an electronically encoded formatting
command which specifies that leading is to be inserted, the maximum
size of the leading at any given lead-out point, the automatic
selection of lead-out points through a priority scheme definition.
The automatic lead-out point assignments include paragraph
boundaries, line boundaries, between title and body, between footnote
and body, and between figures and body.  Another electronic
formatting command is provided for specifying lead-out points
independently of the algorithm.

      The leading command is processed after a page is formatted.
Additional vertical spacing is inserted at the highest priority
lead-out point to achieve the...
