To answer the question directly... no there isn't.
JPG doesn't really define a vector shape, if you zoom in enough, there will be blurry pixels on the edge of the hexagons.
EGC generation requires toolpaths. As I've found out with my first few experiments using Carbide Create, doing some manual selection of the toolpaths can either greatly speed up, or greatly slow down the speed of cutting. (If you create a single toolpath for a single item, it is much faster than selecting a whole bunch of items and making that one toolpath) it's more labor intensive on the front end, but will save a lot of time when cutting.
