[iText-questions] Memory footprint

[Scott Purcell]

Hello,

 

I am creating a multi-page document in whcih I am embedding images. Below, as you can see, I have a table, where the left side is some simple text, and the left side is a embeded thumbnail. All works well, but when I queries upon 10,000 images, the JVM on my local box(testing)  was holding all the data in memory. And of course, I noticed a huge performance impact. So when I run on production, someone can query on 100,000 images, and may bring the box down.

 

So in the case of what I am attempting to do, is there a way to perform virtual writes, while I am creating the document?

 

Thanks,

Scott

 

 

 

 

 

 Paragraph headline = new Paragraph("Query Show Images", headFont);
      headline.setAlignment(Paragraph.ALIGN_CENTER);
      document.add(headline);

 

      String query = "select * from asset where path like '%hiddenval%'";

      RowEnum re = dh.getRows(query);

 

      Table tw = new Table(2);

 

      Cell c1;
      while (re.next()) {
        c1 = new Cell(new Paragraph(re.getString("path")));
        tw.addCell(c1);
        // if image good
        if (isImageValid(re.getString("asset_id"))) {
          c1 = embedImage(re.getString("asset_id"), new Cell());
          tw.addCell(c1);
        } else {
          c1 = new Cell("Default Image.");
          tw.addCell(c1);
        }
      }
      document.add(tw);
