Hi again,
I'm trying to convert simple HTML content (entries from a blog) to a pdf
document.
But sometimes when there's image in it, I'm facing an
EmptyStackException when
the SAXmyHtmlHandler class tries to add it to the document.
Here is the test code :
package personnal.blogprinter;
import java.io.FileOutputStream;
import java.io.StringReader;
import org.junit.Test;
import org.xml.sax.InputSource;
import com.lowagie.text.Document;
import com.lowagie.text.PageSize;
import com.lowagie.text.html.HtmlParser;
import com.lowagie.text.pdf.PdfWriter;
public class PdfiTextImageFailingTest {
@Test
public void testFailingImage() throws Exception {
String htmlContent = "<html><body>\n" +
"<blockquote>" +
"Lorem ipsum dolor sit amet, consectetur
adipiscing elit. Aliquam lectus augue, vehicula molestie placerat ac,
ultrices vitae risus." +
"<p align=\"center\"><img
src=\"file:/path/to/feu.jpg\" /></p>\n" +
"</blockquote>\n" +
"</body></html>\n";
Document document = new Document(PageSize.A4, 50, 50,
50, 50);
PdfWriter.getInstance(document, new
FileOutputStream("test-image.pdf"));
document.open();
HtmlParser parser = new HtmlParser();
InputSource is = new InputSource(new
StringReader(htmlContent));
parser.go(document, is);
document.close();
}
}
And the related stacktrace :
