Yes, specifically the cupsRaster API in libcupsimage (which is
GPL'd, not LGPL'd like libcups)

The pstocupsraster and cgpdftoraster filters are MacOS X specific and
use CoreGraphics to produce raster data.

Keep in mind that Apple only supports a subset of the CUPS raster
modes (see the Apple developer site for the technote on this), so
you'll want to choose a colorspace and color order that is supported
by Apple's filters to be compatible with both Linux and OSX.
