The code below works for me and the gradient appears.

However, if I try to fill a rectangle by following

	contentStream.appendRawCommands("/sh1 sh");

with

        contentStream.setNonStrokingColor(Color.MAGENTA);
        contentStream.fillRect(100,100,100,100);

then the gradient no longer appears nor does the rectangle. If I put the =
rectangle code before the appendRawCommands call, then both the =
rectangle and the gradient appear.

In this simple example, switching the order is an acceptable solution, =
but in the real application that I'm working on, I need to do these =
operations in either order. Is that possible?

Thanks

For the 1.8 version the code is slightly different:

             PDDocument document =3D new PDDocument();
             PDPage page =3D new PDPage();
             document.addPage(page);

             // shading attributes
             COSDictionary dict =3D new COSDictionary();
             dict.setInt(COSName.SHADING_TYPE, 2);
             dict.setName(COSName.COLORSPACE, "DeviceRGB");
             COSArray coords =3D new COSArray();
             coords.add(COSInteger.get(100));
             coords.add(COSInteger.get(400));
             coords.add(COSInteger.get(400));
             coords.add(COSInteger.get(600));
             dict.setItem(COSName.COORDS, coords);

             // function with attributes
             COSDictionary fdict =3D new COSDictionary();
             fdict.setInt(COSName.FUNCTION_TYPE, 2);
             COSArray domain =3D new COSArray();
             domain.add(COSInteger.get(0));
             domain.add(COSInteger.get(1));
             COSArray c0 =3D new COSArray();
             c0.add(COSFloat.get("1"));
             c0.add(COSFloat.get("0"));
             c0.add(COSFloat.get("0"));
             COSArray c1 =3D new COSArray();
             c1.add(COSFloat.get("0.5"));
             c1.add(COSFloat.get("1"));
             c1.add(COSFloat.get("0.5"));
             fdict.setItem(COSName.DOMAIN, domain);
             fdict.setItem(COSName.C0, c0);
             fdict.setItem(COSName.C1, c1);
             fdict.setInt(COSName.N, 1);
             dict.setItem(COSName.FUNCTION, fdict);

             PDShadingType2 shading =3D new PDShadingType2(dict);

             // create and add to shading resources
             page.setResources(new PDResources());
             Map<String, PDShadingResources> shadings =3D new=20
HashMap<String, PDShadingResources>();
             shadings.put("sh1", (PDShadingResources) shading);
             page.getResources().setShadings(shadings);

             // invoke shading from content stream
             PDPageContentStream contentStream =3D new=20
PDPageContentStream(document, page, true, false);
             contentStream.appendRawCommands("/sh1 sh");
             contentStream.close();

             document.save("shtest.pdf");
             document.close();
