Here is an example of how to convert an image to a PDF document in C# using the Syncfusion PDF library. You can convert an image to a PDF document with just a few lines of code. 

//Create an instance of the ImageToPdfConverter class from Syncfusion 
    ImageToPdfConverter imageToPdfConverter = new ImageToPdfConverter(); 

    //Set the page size for the PDF 
    imageToPdfConverter.PageSize = PdfPageSize.A4; 

    //Set the position of the image in the PDF 
    imageToPdfConverter.ImagePosition = PdfImagePosition.TopLeftCornerOfPage; 

    //Specify the file path of the image to be converted to PDF 
    var imageFile = Path.Combine("Autumn Leaves.jpg"); 

    //Create a file stream to read the image file 
    FileStream stream = new FileStream(imageFile, FileMode.Open, FileAccess.Read); 

    //Convert the image to a PDF document using the ImageToPdfConverter 
    PdfDocument document = imageToPdfConverter.Convert(stream); 

    //Create a file stream for the output PDF file 
    using (FileStream outputFileStream = new FileStream(Path.GetFullPath("Output.pdf"), FileMode.Create, FileAccess.ReadWrite)) 
        //Save the generated PDF document to the output file stream 

    //Close the document.
