Hi Craig,

I don't think this is a PDF output problem because I get the same problem with output to a PNG. Also, when I zoom in on the image in Scribus, it is obviously not displaying the full resolution. (i.e. the picture is pixelated at any zoom level above 100%). I think this is an import problem.
