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 differ-
ence 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 "hyphen-
ation" is set to "true" and the parameter "hyphendict" contains
a valid filename for a hyphenation file. The line spac-
ing 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 out-
put 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. De-
faults 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 "numindent-
lines".
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 justi-
fied 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 open-
office, scribus or koffice. You can find their dictio-
naries 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/open-
office/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.
