hi ,
This is santosh here.Actually i have to merge the pdf docs into one
pdf.before this i have to get the content from the database and inseerted
respective content into respective pdf dynamically by using pdfstamper
class and then i save that into one temprary folder.i repeat the same
process for all pdf documents.after this i tried to merge the pdfs which are
in temprary folder by using pdfcontentbyte and i got one single pdf
document.but in that document there is no data which i inserted before .
could u help me if possible with the solution.please send the solution to
this mail only,
The sample code is
public static byte[] MergeFiles(ArrayList sourceFiles)
{
Document document = new Document();
MemoryStream output = new MemoryStream();
try
{
// Initialize pdf writer
PdfWriter writer = PdfWriter.GetInstance(document, output);
//set our custom event to the pdf writer
writer.PageEvent = new PdfPageEvents();
// Open document to write
document.Open();
PdfContentByte content = writer.DirectContent;
// Iterate through all pdf documents
for (int fileCounter = 0; fileCounter < sourceFiles.Count;
fileCounter++)
{
// Create pdf reader
PdfReader reader = new
PdfReader(sourceFiles[fileCounter].ToString());
int numberOfPages = reader.NumberOfPages;
// Iterate through all pages
for (int currentPageIndex = 1; currentPageIndex <=
numberOfPages; currentPageIndex++)
{
// Determine page size for the current page
document.SetPageSize(
reader.GetPageSizeWithRotation(currentPageIndex));
// Create page
document.NewPage();
PdfImportedPage importedPage =
writer.GetImportedPage(reader, currentPageIndex);
// Determine page orientation
int pageOrientation =
reader.GetPageRotation(currentPageIndex);
if ((pageOrientation == 90) || (pageOrientation ==
270))
{
content.AddTemplate(importedPage, 0, -1f, 1f, 0,
0,
reader.GetPageSizeWithRotation(currentPageIndex).Height);
}
else
{
content.AddTemplate(importedPage, 1f, 0, 0, 1f,
0, 0);
}
}
}
}
catch (Exception exception)
{
throw new Exception("There has an unexpected exception" +
" occured during the pdf merging process.",
exception);
}
finally
{
document.Close();
}
return output.GetBuffer();
}
Thanking you.
