6 SPPS_params - This document briefly describes all of the internal
7 parameters of SPPS.
8
10 In calls to GETUSV and SETUSV, which are used to access the internal
11 parameters of SPPS, the arguments VN and IV are as follows:
12 VN (an input constant or variable of type CHARACTER) is the
15 name of a parameter; only the first two characters are
16 meaningful. Remember that, in FORTRAN, a constant of type
17 CHARACTER is a string of characters enclosed in
18 apostrophes.
19 IV (an input or output value of type INTEGER), is either the
22 returned current value of the parameter specified by VN or
23 the desired new value of that parameter, as described in
24 the following table:
25 Parameter Description Possible Values of IV
27 Name (VN)
28 --------- ----------- ---------------------
29 'LS' Axis scaling 1 = linear X, linear Y
30 ("Log Scaling" flag) 2 = linear X, log Y
31 3 = log X, linear Y
32 4 = log X, log Y
33 'MI' Axis direction reversal 1 = neither X nor Y
35 ("MIrroring" flag - axis 2 = X, but not Y
36 from maximum to minimum 3 = Y, but not X
37 rather than min to max) 4 = both X and Y
38 'MU' Metacode output Unit 2
40 'PB' Pen-move Buffer size 2 to 50
42 Both 'LS' and 'MI' are normally set by calling the routine
44 SET, but can be set independently by calling SETUSV.
45 The parameter 'MU' is set, prior to calling OPNGKS, to
47 change the FORTRAN logical unit number to be used by GKS
48 for metacode output.
49 The parameter 'PB' sets the size of the SPPS polyline
51 buffer. The value "2" effectively turns buffering off.
52 Obsolete Description
54 parameters
55 ---------- -----------
56 'XF' X axis exponent for plotter coordinates
57 (The PAU range would be 1 to 2**XF - 1 in X)
58 'YF' Y axis exponent for plotter coordinates
59 (The PAU range would be 1 to 2**YF - 1 in Y)
60 'IR' Red color intensity (relative to green and blue)
61 'IG' Green color intensity (relative to red and blue)
62 'IB' Blue color intensity (relative to red and green)
63 'IM' Maximum color index to be used
64 'IN' Overall color intensity
65 'II' Restore color index
66 'LW' Line width scale factor in thousandths
67 (2000 means double the default line width)
68 'MS' Marker size in thousandths
69 (2000 means double the default marker size)
70 The values of the parameters 'XF' and 'YF' are the same as
72 the values of the arguments IX and IY in calls to the
73 routines SETI and GETSI.
74 The parameters 'IR', 'IG', 'IB', 'IM', 'IN', and 'II' were
76 all part of a color-setting scheme meant to allow overall
77 intensity to be set independently of color. This scheme is
78 now obsolete; it has been replaced by normal GKS color
79 setting through the routines GSCR, GSPLCI, GSFACI, GSPMCI,
80 and GSTXCI. The corresponding GKS inquiry routines to
81 determine current color settings are GQCR, GQPLCI, GQFACI,
82 GQPMCI, and GQTXCI. See Section 6 of "User's Guide for
83 NCAR GKS-0A Graphics."
84 The parameter 'LW' is replaced by the GKS line width scale
86 factor routine, GSLWSC, which has the corresponding query
87 function GQLWSC.
88 The parameter 'MS' is replaced by the GKS marker size scale
90 factor routine, GSMKSC, which has the corresponding query
91 function GQMKSC.
92
94 Values of SPPS parameters are set by calling the routine SETUSV and
95 retrieved by calling the routine GETUSV.
