   My code is bellow:

private PDFLibrary PDFLib = new PDFLibrary();
string sOutputFile = @"C:\my temp\test.pdf";
string sSecondFile = @"C:\my temp\secondfile.pdf";
string sImageFile = @"C:\my temp\thirdfile.jpg";

PDFLib.SaveToFile(sOutputFile);
PDFLib.MergeFiles(sOutputFile, sSecondFile, sOutputFile)
PDFLib.AddImageFromFile(sImageFile, 0);
PDFLib.DrawImage(10, 10, PDFLib.PageWidth() - 10, PDFLib.PageWidth() - 10);

After execute application successfully, My Output File's content is bank.
I don't know what wrong I did. Please help me.

	Hi! I think you have a load before the SaveToFile ... MergeFiles works only on disk... so the first Load (with the old sOutputFile) is still active... So AddImage doesn't touch the new sOutputFile but the old sOutputFile... the old sOutputFile wasn't saved at the end - so the image is lost. Your sequence is wrong ;-) Please read the first threads in the general section from debenu... There are knowledgebase- and sample-sections on the official supportpages. Cheers, Ingo
