gboolean gerber_is_rs274x_p	(	gerb_file_t *	fd,
		gboolean *	returnFoundBinary
	)

Checks for signs that this is a RS-274X file Returns TRUE if it is, FALSE if not.

gboolean gerber_parse_file_segment	(	gint	levelOfRecursion,
		gerbv_image_t *	image,
		gerb_state_t *	state,

	)

This function reads the Gerber file char by char, looking for various Gerber codes (e.g. G, D, etc). Once it reads a code, it then dispatches control to one or another bits of code which parse the individual code. It also updates the state struct, which holds info about the current state of the hypothetical photoplotter (i.e. updates whether the aperture is on or off, updates any other parameters, like units, offsets, apertures, etc.)

static void parse_D_code ( gerb_file_t *  fd, gerb_state_t *  state, gerbv_image_t *  image  )

static

This function reads the numeric value of a D code and updates the state. It also updates the D stats counters

gerbv_image_t* parse_gerb	(	gerb_file_t *	fd,
		gchar *	directoryPath
	)

This is a wrapper which gets called from top level. It does some initialization and pre-processing, and then calls gerber_parse_file_segment which processes the actual file. Then it does final modifications to the image created.
