Code to do this can be found in the Android source tree. The old screenshot tool reads from the framebuffer device and saves it to PNG.

Note this does not work on newer devices, which may use hardware composer overlays to avoid writing to a single framebuffer. On such devices you need to use the screencap tool instead.
