Due to some policy issues I may not be able to provide you the entire code or formats of documents. But I can provide you a detailed explanation of what we are doing. We are building a string by replacing values with placeholders for a html template , this string is used to build PDF. During this process we are getting a exception
While inserting image (logo) at header of PDF. See code snippet below.
This exception occurs only after few hours of business day, Not always .
AsposeDoc = new Aspose.Words.Document();
AsposeBuilder = new DocumentBuilder(AsposeDoc);
AsposeBuilder.CellFormat.WrapText = true;
AsposeBuilder.RowFormat.AllowAutoFit = true;
Aspose.Words.Section currentSection = AsposeBuilder.CurrentSection;
Aspose.Words.PageSetup pageSetup = currentSection.PageSetup;
//pageSetup.Orientation = Aspose.Words.Orientation.Landscape;
pageSetup.LeftMargin = 30;
pageSetup.RightMargin = 30;
//Creating the Header Section
//string strImgPath = "C:\\Images\\Logo.png";
string strImgPath = string.Empty;
if (HttpContext.Current != null && HttpContext.Current.Session != null && HttpContext.Current.Session["AttachmentPath"] != null)
strImgPath = HttpContext.Current.Session["AttachmentPath"].ToString() + poSqlDao.Client + "\\Images\\" + poSqlDao.Client + "_logo.gif";
if (File.Exists(strImgPath))
{
FileStream fs = null;
fs = File.OpenRead(strImgPath);
int fileSize = (int)fs.Length;
byte[] _BufImage = new byte[fileSize];
fs.Read(_BufImage, 0, fileSize);
fs.Close();
fs.Dispose();
pageSetup.DifferentFirstPageHeaderFooter = false;
AsposeBuilder.MoveToHeaderFooter(HeaderFooterType.HeaderPrimary);
pageSetup.HeaderDistance = 2;
AsposeBuilder.StartTable();
double tableWidth1 = pageSetup.PageWidth - pageSetup.LeftMargin - pageSetup.RightMargin;
AsposeBuilder.InsertCell();
AsposeBuilder.Font.Underline = Underline.None;
AsposeBuilder.CellFormat.Width = tableWidth1 * 2 / 3;
AsposeBuilder.CurrentParagraph.ParagraphFormat.Alignment = ParagraphAlignment.Left;
AsposeBuilder.InsertImage(_BufImage);
AsposeBuilder.EndRow();
AsposeBuilder.EndTable();
}
//End Header Logo
// Create a Footer Section to show Page Number
AsposeBuilder.MoveToHeaderFooter(HeaderFooterType.FooterPrimary);
pageSetup.FooterDistance = 10;
AsposeBuilder.StartTable();
double tableWidth = pageSetup.PageWidth - pageSetup.LeftMargin - pageSetup.RightMargin;
AsposeBuilder.InsertCell();
AsposeBuilder.Font.Name = "Arial";
AsposeBuilder.Font.Size = 10;
//AsposeBuilder.CellFormat.Width = tableWidth;
AsposeBuilder.CellFormat.Width = tableWidth;
AsposeBuilder.InsertField("PAGE", "");
AsposeBuilder.Write(" of ");
AsposeBuilder.InsertField("NUMPAGES", "");
AsposeBuilder.CurrentParagraph.ParagraphFormat.Alignment = ParagraphAlignment.Right;
AsposeBuilder.EndRow();
AsposeBuilder.EndTable();
AsposeBuilder.MoveToDocumentEnd();
pageSetup.PaperSize = PaperSize.A4;
pageSetup.TopMargin = 30;
pageSetup.BottomMargin = 10;
AsposeBuilder.InsertHtml(sbPDFData.ToString());
NodeCollection paragraphs = AsposeDoc.GetChildNodes(NodeType.Paragraph, true);
foreach (Aspose.Words.Paragraph paragraph in paragraphs)
{
paragraph.ParagraphFormat.SpaceAfterAuto = false;
paragraph.ParagraphFormat.SpaceAfter = 0;
}
AsposeDoc.Save(strDocumentPath, Aspose.Words.SaveFormat.Pdf);
Thanks,
