Inserting Blank Page to existing document

[alntechnology]

We have an application which we have changed to use Spire.pdf for wcf C# and it is working great.
But when we have a document which is normally in landscape mode and we add a page to the start of the document, it has been reported that it is printing out in portrait mode.

What is the correct way to load an existing pdf into a new instance of the document for manipulation following code has been extracted from the program;

Code: Select all

 PdfDocument documentDrawing = new PdfDocument();
 PdfDocument origionalDrawing = new PdfDocument();
 origionalDrawing.LoadFromFile(Properties.Settings.Default.WOPrintDrawings + PartNo + ".pdf");
 PdfPageBase documentDrawingPage = documentDrawing.Pages.Insert(1, origionalDrawing.Pages[0].Size);
 documentDrawing.InsertPage(origionalDrawing, 0);
 documentWorksOrder.InsertPage(origionalWorksOrder, 0);
 PdfSolidBrush brush = new PdfSolidBrush(Color.Black);
 PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Left);
 PdfFont font = new PdfFont(PdfFontFamily.Helvetica, 13f);
 PdfGraphicsState state = documentDrawingPage.Canvas.Save();
 string datastring = @"Stock No : " + PartNo + @" Account No : " + AccountNo + @" Works Order No : " + WOrderNo;
 SizeF size = font.MeasureString(datastring, format);
 documentDrawingPage.Canvas.DrawString(Properties.Settings.Default.WOrderSpindleDrawing, font, brush, 55, 0, format);
 documentDrawingPage.Canvas.DrawString(datastring, font, brush, 55, 20, format);
 documentDrawingPage.Canvas.Restore(state);
 documentDrawing.SaveToFile(Properties.Settings.Default.WOWorkingFolder + out2);


Thanks in advance

Hello,

Thank you for your inquiry.
I simulated a PDF file and tested it with your code, but didn't found your issue. The version I used is the latest version(Spire.PDF Pack(Hot Fix) Version:7.8.2). If you were not using the latest version, please first give it a try. If the issue still exists after trying, please provide your PDF sample file as well as your resultant PDF for further investigation.

Thanks for the update.

Have had some feed back from the end user and they what to see the inserted blank page in portrait mode and the original document in its original mode which is landscape.

have been checking out the Insert page method I am using but cannot figure out what need to change on it, need to insert an A4 portrait page as the first page.

Hi,

Thank you for your clarification.
I understand your meaning now. Please correct your code as below to insert a A4 page in portrait mode.

Code: Select all

...
//the default page size is A4, orientation is portrait
PdfPageBase documentDrawingPage = documentDrawing.Pages.Insert(1);
documentDrawing.InsertPage(origionalDrawing, 0)
...
