NAME

       PS_show_boxed — Output text in a box

SYNOPSIS

       #include <pslib.h>

       int  PS_show_boxed(PSDoc  *psdoc, char *text, float left, float bottom, float width, float
       height, const char *hmode, const char *feature)

DESCRIPTION

       Outputs a text in a given box. The lower left corner of the box is at (left, bottom).   If
       the height is set to 0.0 the box will become as tall as needed to contain all the text. If
       feature is set to blind no text will be output but the is  set  as  usual.  This  can  for
       example  be  used  to  calculate the box height needed to comprise all text or in order to
       determine how much text fits into a box.

       Line breaks will be inserted where needed. Multiple spaces are treated as one.  Tabulators
       are  treated  as  spaces.  The  parameter  hmode can be "justify", "fulljustify", "right",
       "left", or "center". The difference of "justify" and "fulljustify" just affects  the  last
       line of the box. In fulljustify mode the last line will be left and right justified unless
       this is also the last line of paragraph. In justify mode it will always be left justified.

       The text will be hyphenated if the parameter  "hyphenation"  is  set  to  "true"  and  the
       parameter  "hyphendict" contains a valid filename for a hyphenation file. The line spacing
       is taken from the value "leading". Paragraphs can be separated by an empty line just  like
       in  TeX.  If  the  value  "parindent" is set to value > 0.0 then the first n lines will be
       indented. The number of indented lines is set by the parameter "numindentlines". In  order
       to prevent indenting of the first m paragraphs set the value "parindentskip" to a positive
       number.

USED PARAMETERS

       The output of PS_show_boxed can be configured with several  parameters  and  values  which
       must  be set with either PS_set_parameter(3) or PS_set_value(3). Beside the parameters and
       values which affect text output the following parameters and values are evaluated.

       leading (value)
                 Distance between baselines of two consecutive lines.

       linebreak (parameter)
                 Set to "true" if you want a carrige return  to  start  a  new  line  instead  of
                 treating it as a space. Defaults to "false".

       parbreak (parameter)
                 Set  to  "true"  if  you  want  a carrige return on a single line to start a new
                 paragraph instead of treating it as a space.  Defaults to "true".

       hyphenation (parameter)
                 Set to "true" in order to turn hyphenation on. This requires a dictionary to  be
                 set with the parameter "hyphendict". Defaults to "false".

       hyphendict (parameter)
                 Filename of the dictionary used for hyphenation pattern (see below).

       hyphenminchar (value)
                 The number of chars which must at least be left over before or after the hyphen.
                 This implies that  only  words  of  at  least  two  times  this  value  will  be
                 hyphenated.  The  default value is three. Setting a value of zero will result in
                 the default value.

       parindent (value)
                 Set the amount of space in pixel for indenting the first m lines of a paragraph.
                 m can be set with the value "numindentlines".

       parskip (value)
                 Set  the amount of extra space in pixel between paragraphs.  Defaults to 0 which
                 will result in a normal line distance.

       numindentlines (value)
                 Number of lines from the start of the paragraph which will be indented. Defaults
                 to 1.

       parindentskip (value)
                 Number  of  paragraphs  in  the box whose first lines will not be indented. This
                 defaults to 0. This is useful for paragraphs right after a  section  heading  or
                 text being continued in a second box. In both case one would set this to 1.

       linenumbermode (parameter)
                 Set  how lines are to be numbered. Possible values are "box" for numbering lines
                 in the whole box or "paragraph" to number lines within each paragraph.

       linenumberspace (value)
                 The space for the column left of the numbered line containing the  line  number.
                 The line number will be right justified into this column. Defaults to 20.

       linenumbersep (value)
                 The  space between the column with line numbers and the line itself. Defaults to
                 5.

HYPHENATION

       Text is hyphenated if the parameter "hyphenation" is set to true and a  valid  hyphenation
       dictory  is  set.  pslib  does  not  ship its own hyphenation dictionary but uses one from
       openoffice, scribus or koffice.  You can find their dictionaries for  different  languages
       in    one    of    the    following    directories   if   the   software   is   installed:
       /usr/share/apps/koffice/hyphdicts/,              /usr/lib/scribus/dicts/,               or
       /usr/lib/openoffice/share/dict/ooo/.   Currently scribus appears to have the most complete
       hyphenation dictionaries.

RETURN VALUE

       Number of charactes that could not be written. This  function  will  also  set  the  value
       "boxheight" to the actual height of the box. This enables you to put several boxed beneath
       each other and keep the propper line spacing.
