Text is superimposed on image by default when converting html using HTMLWorker

[tommyp]

Hi everyone,
I'm having a really annoying problem converting html to pdf. I'm using HTMLWorker and no stylesheet, trying to convert a rather simple html page with images.
My problem is, that the text on the page is superimposed on the images, as if the images were background images, or underlying.
I am not changing any attributes etc. during my HTMLWorker processing, and the alignment attribute is 0.

Any ideas about what could be the problem - any ideas are appreciated.

Thanks
>Tommy

Try using this one....
 document.SetMargins(40, 50, 25, 30)
dim tempPath as string= Some path
dim   strPDFpath = Server.MapPath("~/PDFS/TempPDFS/") & tempPath
                        Dim styles As New iTextSharp.text.html.simpleparser.StyleSheet()
                        'styles.LoadTagStyle("ol", "leading", "16,0")
                        Dim fs As New FileStream(strPDFpath, FileMode.Create, FileAccess.Write)
                        PdfWriter.GetInstance(document, fs)
                        Dim path As String = Server.MapPath("~/App_Themes/MainTheme/")
                        path = path & "main.css"
                        document.Add(New Header(iTextSharp.text.html.Markup.HTML_ATTR_STYLESHEET, path))

                        Dim objects As ArrayList

                        styles.LoadTagStyle("li", "face", "garamond")
                        styles.LoadTagStyle("span", "size", "8px")
                        styles.LoadTagStyle("body", "font-family", "times new roman")
                        styles.LoadTagStyle("body", "font-size", "10px")
                        'styles.LoadTagStyle("HR", "page-break-after", "always")
                        document.Open()

                        document.NewPage()
                        'Add footer
                        Dim footer As New HeaderFooter(New Phrase(" "), False)
                        footer.Border = 0
                        footer.Alignment = iTextSharp.text.Element.ALIGN_CENTER
                        document.Footer = footer

                        'Dim headerPhrase As New Phrase("-")
                        'Dim header As New HeaderFooter(headerPhrase, False)
                        'header.Border = iTextSharp.text.Rectangle.NO_BORDER
                        'header.Alignment = iTextSharp.text.Element.ALIGN_LEFT
                        'header.BackgroundColor = iTextSharp.text.Color.WHITE
                        'document.Header = header

                        'doc.Add(headerPhrase)
                        'objects=itextsharp.text .html .simpleparser .HTMLWorker .
                        objects = iTextSharp.text.html.simpleparser.HTMLWorkerExtended.ParseToList(New StreamReader(strHTMLpath, Encoding.[Default]), styles)

                        For k As Integer = 0 To objects.Count - 1
                            document.Add(DirectCast(objects(k), IElement))
                        Next
                        document.Close()

Thanks for your answer.
However, had some problems working out exactly what would make your solution fix my problems.
Now I found that when the img-tag is lacking the align attribute I get the problems - when I add the align attribute I do not have the problem.
Now, using my CMS we normally do not use align's and try to position everything using css stylesheets instead.
Any ideas about how to handle this? I'm thinking some css-tricks forcing iTextSharp to react like if an align were present, or maybe some special handling in the HTMLWorker processing?
