These run on the same hardware, so of course, someone could implement Core Graphics on Linux. However, nobody has as far as I know, and I think it would be rather expensive and time consuming to implement that. It seems it was cheaper for Imgix to use Core Graphics rather than implement it themselves on Linux.
