I am doing a conversion from HTML to PDF, trying to use the existing
tools. For this particular case I have cheated and fixed the "table"
entry to have columns that are reasonable for the application (as you
will see below). The problem I am having now is that the output file
is quite large relative to what it needs to be, and I believe it is
because this approach duplicates all of the jpeg images contained in
the file, which in this case turns what should be a 200K PDF file into
a 3Meg PDF file.
It seems to me that iText might want to create a hashtable of images
so that, instead of including one after another, it only includes one
of each and then points to them. I know too little about PDF to do
this myself, but I am wondering if anyone else has thought through
this - done it before - or if it is a simple fix to the HTML reader or
PDF writer, whether it is likely to appear in an update soon... Or is
there a way to do this by parsing the PDF directly?
Here is sameple code as it runs reasonably well today - except for the
size problem.
File ff = new File(OutP);if (ff.exists()) {ff.delete();}
com.itextpdf.text.Document d = new com.itextpdf.text.Document
(PageSize.LETTER, 40, 40, 40, 40);
try {PdfWriter.getInstance(d, new FileOutputStream
(OutP));d.open ();
FileReader fr = new FileReader(OutF);
ArrayList elementlist =
com.itextpdf.text.html.simpleparser.HTMLWorker.parseToList(fr, null);
for (int i = 0; i < elementlist.size(); i++)
{com.itextpdf.text.Element element =
(com.itextpdf.text.Element)elementlist.get(i);
if (ShowCount.equals("T")) {if (element.type() ==
23) {float [] f = new float[] { 0.10f, 0.90f};
PdfPTable
p;p=(PdfPTable)element;p.setWidths(f);}}
d.add(element);}
d.close ();
} catch(Exception de) {System.err.println("Ouch!!! "
+ de.getMessage());return(-2);}
