I tried your sample with my approach and see the problem. Do you have any suggestions for options to use with pdftocairo? I tried pdf2cairo -png input.pdf output.png and the output wasn't anywhere near as good as what I see if I look at the pdf with preview on my Mac. It's frustrating that a PDF viewer does such a great job of rasterizing the image and the only way I can get an equivalent .png is to take a screen shot of it.
