Here’s the code to replace images in PDFs, in Java and C#. It will replace the first image in the first page.
PdfReader pdf = new PdfReader("in.pdf");
PdfStamper stp = new PdfStamper(pdf, new FileOutputStream("c:\\out.pdf"));
PdfWriter writer = stp.getWriter();
Image img = Image.getInstance("image.png");
PdfDictionary pg = pdf.getPageN(1);
PdfDictionary res =
(PdfDictionary)PdfReader.getPdfObject(pg.get(PdfName.RESOURCES));
PdfDictionary xobj =
(PdfDictionary)PdfReader.getPdfObject(res.get(PdfName.XOBJECT));
if (xobj != null) {

This choropleth uses a threshold scale for quantization, mapping arbitrary slices of a continuous domain to discrete values in the range. Unemployment rates ranging from 2 to 10% are quantized into different shades of purple.

var color = d3.scale.threshold()
    .domain([.02, .04, .06, .08, .10])
    .range(["#f2f0f7", "#dadaeb", "#bcbddc", "#9e9ac8", "#756bb1", "#54278f"]);
