Abstract

When imaging a document which contains horizontally aligned presentation spaces on one or more of its pages, such as columns, a function is needed to horizontally align the first and last lines across two or more of these presentation spaces.

White Space Compression Or Expansion

      When imaging a document which contains horizontally aligned
presentation spaces on one or more of its pages, such as columns, a
function is needed to horizontally align the first and last lines
across two or more of these presentation spaces.

      First and last data lines within horizontally aligned
presentation spaces are themselves horizontally aligned by providing
an alignment parameter on the presentation space definition function.
To align lines, an Object Area Format Flags parameter is placed on
the Object Area Descriptor (OBD) structured field.  When off, bit 6
of the Object Area Format Flags parameter specifies that white space
within the presentation area defined by the OBD structured field can
be compressed or expanded when the data is imaged.

      The method of compression or expansion is decided upon by the
application or device imaging the data.  White space at the top and
bottom borders of the presentation spaces may be increased or
decreased as well as the leading between one or more lines of the
data to achieve the required visual effect.

      The described method provides a simple way to specify balancing
of data between columns of an imaged page.  The function also
provides an efficient way to align associated text, such as the
English translation for a clause, paragraph, etc., that is written
and displayed in German.

      The English text can be entered into a document and assigned...
