ITextSharp pdf image from resource file
I am creating a pdf file using iTextSharp in Windows Forms using C #, I want to add an image to the file from the Resource folder (image name: LOGO.png). I have an ExportToPdf.cs class and this class is located in the App_Class folder. I am using the code below. Can anyone please help.
internal static void exportEchoReport(Patient p)
{
using (var ms = new MemoryStream())
{
using (var doc1 = new iTextSharp.text.Document(PageSize.A4, 50, 50, 15, 15))
{
try
{
PdfWriter writer = PdfWriter.GetInstance(doc1, new FileStream("echo.pdf", FileMode.Create));
doc1.Open();
string imagePath = // I want to use this image LOGO.png (Resources.LOGO)
iTextSharp.text.Image logoImg = iTextSharp.text.Image.GetInstance(imagePath);
PdfPTable headerTable = createTable(logoImg, p);
doc1.Add(headerTable);
}
catch (Exception ex)
{
}
finally
{
doc1.Close();
}
}
System.Diagnostics.Process.Start("echo.pdf");
}
}

Visual Studio makes IMHO the dubious decision to store image files as System.Drawing.Bitmap
, (in your code above Resources.LOGO
) instead of byte[]
as it does with other binaries. Therefore, you need to use one of the overloaded methods Image.GetInstance()
. Here's a simple example:
using (var stream = new MemoryStream())
{
using (var document = new Document())
{
PdfWriter.GetInstance(document, stream);
document.Open();
var image = Image.GetInstance(
Resources.LOGO, System.Drawing.Imaging.ImageFormat.Png
);
document.Add(image);
}
File.WriteAllBytes(OUTPUT_FILE, stream.ToArray());
}
