Put image on existing PDF

[Ben]

Hi there,

I have an existing PDF and want to put an image at a certain x and y position and save the result into a new PDF. Is there someone who can provide a sample on how to achieve this?

Thanks in advance!

Hi Ben,

You can achieve the desired functionality by importing the existing PDF document into a RadFixedDocument using the PdfFormatProvider:

RadFixedDocument document = new RadFixedDocument();

PdfFormatProvider provider = new PdfFormatProvider();
using (Stream input = File.OpenRead("SampleDocument.pdf"))
{
	document = provider.Import(input);
}

Then you can insert an image on a specific Position using the FixedContentEditor and ImageSource object:

ImageSource imageSource;
using (FileStream source = File.Open("image.png", FileMode.Open))
{
	imageSource = new ImageSource(source);
}

RadFixedPage firstPage = document.Pages.First();
FixedContentEditor editor = new FixedContentEditor(firstPage);

editor.Position.Translate(offsetX: 150, offsetY: 200);
editor.DrawImage(imageSource);

 And finally to export the RadFixedDocument to a new PDF file:

string exportedDocument = "Exported.pdf";

using (Stream output = File.OpenWrite(exportedDocument))
{
	provider.Export(document, output);
}

I am attaching the project I created in order to test this scenario. Please, feel free to modify it in a way closer to your scenario.

I hope this helps. Please, let me know if there is anything else I can assist you with.
