+# PLSET.H -- User global defines for the Pixel List (image mask) package.

+define	PL_MAXDIM	7		# maximum mask dimensionality
+define	PL_MAXDEPTH	27		# max mask depth, pixels
+define	PL_NOTEQUAL	0		# two masks are not equivalent
+define	PL_EQUAL	1		# two masks are equivalent
+define	PL_UPDATE	1		# enable overwrite of existing savefile
+
+# PLSETI/PLSTATI parameter codes.
+define	P_PRIVATE1	1		# used by client, e.g., PMIO
+define	P_PRIVATE2	2		# used by client, e.g., PMIO
+define	P_MAXLINE	3		# used to size dynamic line buffers
+define	P_DEPTH		4		# mask pixel depth, bits (1=boolean)
+
+# Range list definitions.  For applications which access mask lines as range
+# lists (ranges of constant nonzero value) rather than as pixel arrays.
+# Here, $1 = rl (the range-list array).

+define	PD_SUMMARY	1		# print mask summary information
