[iText-questions] HR tag error - Object reference not set to an instance of an object.
Hello, I am using the FreeTextBox control to write the text, which then I want
to export to pdf. I am using iText# of course. all works very nicely untill I
use the hr tag, (the insert rule button). when I want to export to pdf, I get
the error.This is the C# code I use: private byte[] RanderHTMLtoPDF(string html)
{
byte[] doc = null;iTextSharp.text.Document idocument = new
iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 32, 32, 50, 50);
using (MemoryStream m = new MemoryStream())
{
iTextSharp.text.pdf.PdfWriter.GetInstance(idocument, m);
idocument.Open();using (TextReader sReader = new
StreamReader(new MemoryStream(System.Text.Encoding.Default.GetBytes(html)),
Encoding.Default))
{
iTextSharp.text.html.simpleparser.HTMLWorker worker = new
iTextSharp.text.html.simpleparser.HTMLWorker(idocument);
worker.StartDocument();
worker.Parse(sReader);
worker.EndDocument();
}
idocument.Close();doc = m.ToArray();
}
return doc;
} At the worker.Parse(sReader); it crashes. the error is:ERROR: Object
reference not set to an instance of an object.

Re: [iText-questions] HR tag error - Object reference not set to an instance of an object.
Could you please guide me to a link where there is an implementation example in
C# that could help me write with XMLWorker what I wrote here with HMTL worker?
private byte[] RanderHTMLtoPDF(string html)
{
byte[] doc = null;
iTextSharp.text.Document idocument = new
iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 32, 32, 50, 50);
using (MemoryStream m = new MemoryStream())
{
iTextSharp.text.pdf.PdfWriter.GetInstance(idocument, m);
idocument.Open();
using (TextReader sReader = new StreamReader(new
MemoryStream(System.Text.Encoding.Default.GetBytes(html)), Encoding.Default))
{
iTextSharp.text.html.simpleparser.HTMLWorker worker = new
iTextSharp.text.html.simpleparser.HTMLWorker(idocument);
worker.StartDocument();
worker.Parse(sReader);
worker.EndDocument();
}
idocument.Close();
doc = m.ToArray();
}
return doc;
}
I can't make the transition to XMLWorker and I am a bit pressed by time

[iText-questions] Line spacing
Hello, Could you please give me a little help for my problem? I am using the
FreeTextBox to create a html text that later I want to export to pdf. I am
using iText# and the HTMLWorker. This is my code: private byte[]
RanderHTMLtoPDF(string html)
{
byte[] doc = null;iTextSharp.text.Document idocument = new
iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 32, 32, 50, 50);
using (MemoryStream m = new MemoryStream())
{
iTextSharp.text.pdf.PdfWriter.GetInstance(idocument, m);
idocument.Open();using (TextReader sReader = new
StreamReader(new MemoryStream(System.Text.Encoding.Default.GetBytes(html)),
Encoding.Default))
{
iTextSharp.text.html.simpleparser.HTMLWorker worker = new
iTextSharp.text.html.simpleparser.HTMLWorker(idocument);
worker.StartDocument();
worker.Parse(sReader);
worker.EndDocument();
}
idocument.Close();doc = m.ToArray();
}
return doc;
} the problem is that in PDF, the line spacing is too big and the client
wants it smaller. and I couldn't find a solution to do that. Thanks, Gabriel

Re: [iText-questions] Line spacing
Hi,yes, I know it has beed discontinued in favor of XML Worker. I had a problem before with the hr tag I think, and I got the same answer, but I couldn't change it with XML Worker. I tried to use xml worker instead, couldn't. The guy who wrote this before left and I had to take over. I didn't have enough time to do this so I just replaced programatically the hr tag with string.empty as I didn't need it.but now I got this new problem and I really cannot work it out. is there a way I can use the html worker so I don't have to change the whole thing, and make the line spacing in the html I receive smaller? thanks Hi Gabriel, 2012/4/2 Stefanescu Gabi sbiga@...

Unfortunately, free support on this mailing-list is only given for the latest versions of iText. If you are lucky, some other subscriber might have solved the same problem and provide you with an answer, but that I can't assure. If keeping HTMLWorker is that critical for you, you might consider contacting the sales department and inquire for premium technical support http://itextpdf.com/support.php#premium Please note that I'm not affiliated in any way with the iText companies, so I might be wrong in assuming that support for deprecated products might be purchased.
