Description
This article describes how to import two PDF documents and merge their first pages into a new single page.
Solution
The following example demonstrates how to use the PdfStreamWriter in order to import and merge the first pages of two different documents into a new single page.
Example
string firstDocument = "SampleDocument1.pdf";
string secondDocument = "SampleDocument2.pdf";
string exportedPdf = "Merged.pdf";
if (File.Exists(exportedPdf))
{
File.Delete(exportedPdf);
}
using (FileStream fileStream = File.OpenWrite(exportedPdf))
{
using (PdfStreamWriter fileWriter = new PdfStreamWriter(fileStream))
{
using (PdfFileSource firstDocumentToMerge = new PdfFileSource(File.OpenRead(firstDocument)))
using (PdfFileSource secondDocumentToMerge = new PdfFileSource(File.OpenRead(secondDocument)))
{
PdfPageSource firstDocumentPageToMerge = firstDocumentToMerge.Pages[0];
PdfPageSource secondDocumentPageToMerge = secondDocumentToMerge.Pages[0];
double largestPageHeight = Math.Max(firstDocumentPageToMerge.Size.Height, secondDocumentPageToMerge.Size.Height);
Size size = new Size(firstDocumentPageToMerge.Size.Width + secondDocumentPageToMerge.Size.Width, largestPageHeight);
using (PdfPageStreamWriter newPage = fileWriter.BeginPage(size))
{
newPage.WriteContent(firstDocumentPageToMerge);
double offsetX = newPage.PageSize.Width / 2;
newPage.ContentPosition.Translate(offsetX, 0);
newPage.WriteContent(secondDocumentPageToMerge);
}
}
}
}
