NAME

       pagesizes - HylaFAX page size definitions

DESCRIPTION

       The pagesizes database defines the page dimensions and guaranteed reproducible areas (GRA)
       for well-known page sizes.  The GRA is the portion of the page that is  guaranteed  to  be
       imaged  during  facsimile  transmission.  This region is typically less than the full page
       dimensions because of paper roller contacts and other mechanical aspects of  the  printing
       process in a facsimile machine.

       All  HylaFAX  programs  that  require page size information read the information from this
       database using a page size name.  Documents should be prepared such  that  the  full  page
       dimensions are employed with the imaged area contained within the GRA.

       The  system-wide default page size to use in preparing documents for transmission is given
       by the ``default'' entry in the database.  (NB: the default entry should be placed last so
       that inverse matches find the real page size name and not the default entry.)

       The page size database is an ASCII file with the following format.  Each entry consists of
       whitespace-separated fields:
       name  abbrev  width  height  gra-width  gra-height  top-margin  left-margin
       Fields have the following interpretation:

       name        the full name for the page size; e.g. ISO A4;

       abbrev      an abbreviated version of the full name for use in compact  listings  such  as
                   the receive queue listing printed by faxstat(1);

       width       the full width of the page;

       height      the full height of the page;

       gra-width   the width of the GRA;

       gra-height  the height of the GRA;

       top-margin  the margin between the top of the full page and the top of the GRA;

       left-margin the margin between the left side of the full page the left side of the GRA.

       The  first  two  fields  must  be  separated from the subsequent fields by a tab character
       (possibly followed by more whitespace); this is done to easily permit blank characters  to
       be  included  in  names.   Otherwise  fields can be separated by any amount of any kind of
       whitespace.  Numbers are all base 10 and in basic  measurement  units  (BMU);  defined  as
       1/1200 x 25.4 millimeters for paper output with a scale factor of one.  All fields must be
       present on a single line; otherwise the entry is ignored.  Comments are introduced by  the
       ``#'' character and continue to the end the line.

       Page  size database lookups are either by name or by page dimensions.  Lookups by name are
       done by sequentially scanning the entries in the database for the first entry that  has  a
       matching  abbreviation  or  substring of the page size name field.  The string comparisons
       ignore case so, for example, ``a4'' would match a full name of  ``ISO  A4''.   Lookups  by
       dimension scan the entire database and return the page with the closest dimensions using a
       straightforward distance metric.  If the difference in dimensions of the closest match  is
       greater  than  1/2  inch  on  each  side,  then  no page entry is returned for a lookup by
       dimension.
