How to merge multiple PDF's of different sizes into one PDF with uniform pages.

[Karla Franke]

I am reading multiple pdf files into a stream and merging into one PDF document.  It works great if all the pages are the same standard size 8.5" x 11'.  Sometimes one of the multiple documents is a different size, so I need to know how to resize the pdf documents to the legal size 8.5" x 14", so the original document is visible and readable.

Hi Karla, 

Thank you for contacting Syncfusion support. 

Currently we do not have support to resize the existing PDF document. However, as a workaround we can able to resize the existing PDF documents by using PdfTemplate. So, we recommend to resize the all PDF documents to similar size and merge those PDF documents into one PDF document. Please try the below sample code snippet for resize the existing PDF document pages and let us know the result. 

 

Note: Please assign required resize value for highlighted variables. 

// Create a new instance of PdfLoadedDocument class.  

PdfLoadedDocument document = new PdfLoadedDocument(path);  

  

// Create a new instance of PdfDocument class.   

PdfDocument doc = new PdfDocument();  

   

SizeF size = new SizeF(document.Pages[0].Size.Width + left + right, document.Pages[0].Size.Height + top + bottom);  

  

//Need to set page size here, if not it will use default size.  

doc.PageSettings.Size = size;  

   

for (int i = 0; i < document.Pages.Count; i++)  

{  

   PdfTemplate template = document.Pages[i].CreateTemplate();  

   PdfPage page = doc.Pages.Add();  

  

   // Create Pdf graphics for the page.  

   PdfGraphics g = page.Graphics;  

  

   g.DrawPdfTemplate(template, new PointF(0, 0), new SizeF(page.GetClientSize().Width, page.GetClientSize().Height));  

}  

  

doc.Save("output.pdf”); 

Once resized the existing PdfDocuments then merge those PDF documents. Kindly find the below link to get more details,
