How can I generate a thumbnail of a specific page in a PDF on the command line in OS X?

I need to be able to generate a png thumbnail of a specific page of a PDF document in OS X.

I can use 'qlmanage -p MyFile.pdf -o outputDir -s1000' to get a 1000-pixel wide PNG of the first page. This works perfectly, and is almost exactly what I need. The only missing piece is being able to specify a certain page number of the PDF.

Can this be done with qlmanage, or some other command-line utility?

You can use Aspose.Pdf to generate a thumbnail (or image) of any page. Very reliable and generates a perfect image (as good as Acrobat). Only downside is it takes ~20 SECONDS to generate a single thumbnail. And that sucks. Code is as follows:

    Document document = new Document(pdfPath);
    Page page = document.Pages[pageNum];
    document.RemoveMetadata();
    page.Flatten();
    page.SendTo(new PngDevice(page.PageInfo.Width, page.PageInfo.Height), pngPath);
    document.Dispose();

ImageMagick ought to be able to help:

convert -resize 10000x10000 MyFile.pdf[2] MyOutput.png

Where 2 is the page number. Enjoy!
