    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);
     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.
