How to Add image in pdf using C# and iTextSharp?

I need your help adding an image to a PDF.

I'm using:

string imgPath2 = localPath + "\\TempChartImages\\" + LegendPath;
img2.Save(imgPath2);
ith.WriteImage(imgPath2, 80);

But this code gives me the error:

Use of unassigned local variable img2

How can I solve this error?

You have to create a getinstance of the image.

iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance("path of the image");

I believe you have to instantiate first the Image.

Image img2 = new Image();

it solved my problems. Hope it will solve yours.

it's a hunch, but if you're assigning the value of img2 inside a Try-Catch block you might be hitting an exception that prevents the assignment from taking place. For example:

var img2;
try
{
    var x = 5 / 0; // Generate a DivideByZero exception
    img2 = GetImage(); // <-- the above exception will prevent this code from executing
}
catch
{
}
img2.Save(imgPath2); <-- img2 wasn't assigned, so another exception will occur

When you declare a variable, in your case img2, without assigning a value it is pointing to absolutely nothing. Make sure you initialize img2 to something before using it.

I think what you want your img2.Save line to be changed to:

Image img2 = Image.FromFile(yourInitialImageHere);  // You could be reading from memory as well.
img2.Save(imgPath2);

I could be way off though as your snippet of code is pretty vague.

Here is the iTextSharp tutorial on images. Without seeing more of your code, it's tough to judge what piece of code from this you'll need.

You'll need some third-party tool for this.
