Not sure what you mean by a vector object or carrier, but generally a
"vector image" is a series of instructions of lines and curves
to draw rather than an array of pixels.

Jpeg, PNG and GIF are all arrays of pixels just compressed in different
ways. I'm pretty sure you can't have vector pngs in that sense.
