CMYK Support

Is it possible to add CMYK support? Poppler seems to support it.

Hi!
You have problems with rendering or with something else? Could you describe your problem and, if possible, provide sample PDF file?

Hi @blackbeam, I don't have a problem at all, on the contrary, it works incredibly well.

The only problem I'm facing is that I need to create CMYK images from a PDF file and that is not supported since RGB is hard coded.

When I compile Poppler with SPLASH_CMYK, and node-gyp rebuild then the library stops working at all.

It will be really great if I could do something like this:

pdf.renderToFile('filename.jpg', 'jpeg', 300, {quality: 100, colorspace: 'cmyk'});

Does the version of jpeg/jfif used support CMYK? IIRC TIFF is an option.
