ldp_print - print tool/script for DocBook SGML/XML documents
|
||||
######################################################################
|
||||
|
||||
This process/script is used in the production environment for the
|
||||
LDP. It relies on the HTMLDOC software package (GPL'ed) which can be
|
||||
obtained from the Easy Software Products (c) web site:
|
||||
|
||||
http://www.easysw.com/htmldoc/
|
||||
|
||||
This process creates a PDF variant from the single-file HTML
|
||||
representation of a DocBook SGML (or XML) instance. The simple
|
||||
wrapper script (ldp_print) assumes that the file was created using
|
||||
{open}jade in a manner similar to:
|
||||
|
||||
jade -t sgml -i html -V nochunks -d $style $fname > $fname.html
|
||||
|
||||
Give the script the filename as an argument. It will then parse the
|
||||
file into 'title.html' and 'body.html' and send each to htmldoc (as
|
||||
the corresponding title page and body of the document).
|
||||
|
||||
|
||||
CAVEATS
|
||||
=======
|
||||
|
||||
o Assumes perl is in /usr/bin; adjust if necessary
|
||||
|
||||
o You may need to specify where the htmldoc executable resides.
|
||||
The script assumes it's within your $PATH.
|
||||
|
||||
o If you want Postscript as an output variant, uncomment the
|
||||
appropriate lines (see below).
|
||||
|
||||
o Relies on output from a DocBook instance created via DSSSL/{open}jade!
|
||||
|
||||
o Cleans up (removes) the intermediate files it creates (but not the
|
||||
PDF or Postscript files, obviously!)
|
||||
|
||||
o Works silently; PDF (PostScript) will be created in the same directory
|
||||
as was specified for the input (single-file HTML) file.
|
||||
|
||||
o Provided without warranty or support!
|
||||
|
||||
o I ran into a problem with htmldoc v1.8.8 which required a source
|
||||
code change (I was getting a core dump from the htmldoc process).
|
||||
Here is the change required:
|

htmldoc/ps-pdf.cxx :
