现在的版本是3.18版,记得在引用里导入itextsharp.下面的代码是把图象合并到一个多页pdf的例子.
private void process(string[] files, string newpdf)
{
iTextSharp.text.Document document = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 25, 25, 25, 25);
try
{
iTextSharp.text.pdf.PdfWriter.GetInstance(document, new FileStream(newpdf, FileMode.Create, FileAccess.ReadWrite));
document.Open();
iTextSharp.text.Image image;
for (int i = 0; i < files.Length; i++)
{
image = iTextSharp.text.Image.GetInstance(files[i]);
if (image.Height > iTextSharp.text.PageSize.A4.Height - 25)
{
image.ScaleToFit(iTextSharp.text.PageSize.A4.Width - 25, iTextSharp.text.PageSize.A4.Height - 25);
}
else if (image.Width > iTextSharp.text.PageSize.A4.Width - 25)
{
image.ScaleToFit(iTextSharp.text.PageSize.A4.Width - 25, iTextSharp.text.PageSize.A4.Height - 25);
}
image.Alignment = iTextSharp.text.Image.ALIGN_MIDDLE;
//image.SetDpi(72, 72);
document.NewPage();
document.Add(image);
//Phrase phrase3 = new Phrase("dreign@163.com\n", FontFactory.GetFont(FontFactory.TIMES, 9, iTextSharp.text.Font.NORMAL, new iTextSharp.text.Color(192, 192, 192)));
//document.Add(phrase3);
}
}
catch (Exception ioe)
{
MessageBox.Show(ioe.Message);
}
document.Close();
}
