Removing last page from document results in error

I’m generating pdf files based on database info. I’m not clear why, but currently it appends a single blank page to the end of the completed document. I was hoping to just delete that final blank page, but when I try I get a “stream is not writeable” error.

Here’s how it’s coded right now:

var pdf = new Pdf();
var section = pdf.Sections.Add();
var marginInfo = new Aspose.Pdf.Generator.MarginInfo();
marginInfo.Top = topMargin;
marginInfo.Bottom = marginInfo.Left = marginInfo.Right = MarginOneInch;
section.PageInfo.Margin = marginInfo;
section.TextInfo.FontSize = 12;
section.TextInfo.LineSpacing = 1.5F;
Aspose.Pdf.Generator.Text t = new Text(stringBuilderContainingInfo.ToString());
t.IsHtmlTagSupported = true;
section.Paragraphs.Add(t);
pdf.Save(“c:\someFileName.pdf”);
Document d = new Document(“c:\someFileName.pdf”);
d.Pages.Delete(d.Pages.Count);
d.Save();

Why does this not work?

Hi Scott,


The development team has further investigated the issue reported earlier and in order to resolve this problem, we recommend using the new Document Object Model (DOM) of Aspose.Pdf namespace. Please try using the following code snippet to resolve the issue.

[C#]

Aspose.Pdf.Document
doc = new Aspose.Pdf.Document();<o:p></o:p>

//add a new page with text and change its page size-ignored

Page page = doc.Pages.Add();

Aspose.Pdf.MarginInfo marginInfo = new Aspose.Pdf.MarginInfo();

marginInfo.Top = 10;

marginInfo.Bottom = marginInfo.Left = marginInfo.Right = 72;

page.PageInfo.Margin = marginInfo;

TextFragment t = new TextFragment("Manufactured on a modern- efficient chassis line and a state of the art cab line using robotic processes and with unmatched confort features, we have made every investment to ensure that the Chief delivers on quality, durability and reliability. We are confident of making significant headway in the fast - growing ABC market - with the new Chief,\" said Robert Gross, TY, Chuck Spencer. Specifically engineered to meet evolving customer expectations in the areas of performance, comfort and realiability, the Chief promises to make our customers more profitable by offering them a tailor-made product solution to meet ther needs and certainly will be a game-changer for them,\" he said.");

t.TextState.FontSize = 12;

t.TextState.LineSpacing = 1.5F;

page.Paragraphs.Add(t);

doc.Save(outFile);

Aspose.Pdf.Document d = new Aspose.Pdf.Document(outFile);

d.Pages.Delete(d.Pages.Count);

string outFile = "c:/pdftest/37210.pdf";

d.Save(outFile);

Hi Scott,


In addition to above reply. Please note to support IsHtmlTagSupported feature for adding HTML string into PDF document using new generator(DOM), we have already logged a feature request as PDFNEWNET-35804 in out issue tracking system. Hopefully HTMLFragment class will be implement in upcoming release of Aspsoe.Pdf for .NET i.e. 9.5 for new generator. However we will notify you via this forum thread as soon as it is fixed and added into new release.

Please feel free to contact us for any further assistance.

Best Regards,

The issues you have found earlier (filed as PDFNEWNET-35804;PDFNEWNET-37210) have been fixed in Aspose.Pdf for .NET 9.5.0.
