Right - in fact I already have them all in memory in an ImageIcon
array, properly scaled and all... What I really want to do is simply
tell the html parser to use these instead of building new ones. By the
way, what exactly do I add the "setProviders(map);" to? The code I
have is only this:
HashMap map = new HashMap(); map.put("img_provider", new
MyImageFactory());
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);
HashMap map = new HashMap(); map.put("img_provider", new
MyImageFactory()); d.setProviders(map);
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);
d.add(element);}
d.close ();
} catch(Exception de) {System.err.println("Ouch!!! "
+ de.getMessage());return(-2);}
I can't do d.setProviders(map) or
com.itextpdf.text.html.simpleparser.HTMLWorker.setProviders(map) or
fr.setProviders(map), and I can't figure out what to associate it
with...
