NAME

6       Conpack - Provides a sort of tool kit of FORTRAN subroutines that can
7       be called in various combinations to draw different kinds of contour
8       plots.
9

SYNOPSIS

11       CPBACK - Draws a background for a contour plot.
12
13       CPCICA - Incorporates into a user's cell array color indices determined
14       by examining where the user's contours lie relative to the cell array.
15
16       CPCLAM - Adds contour lines to an area map. This is part of the process
17       of drawing a solid-fill contour plot.
18
19       CPCLDM - Draws contour lines masked by an existing area map. The object
20       of this may be simply to avoid drawing contour lines through label
21       boxes, but the routine may be used for more complicated tasks, like
22       limiting the drawing of contour lines to the ocean areas on an Ezmap
23       background.
24
25       CPCLDR - Draws contour lines.
26
27       CPCLTR - Traces the contour lines at a given level and retrieves them
28       for some sort of user-defined processing.
29
30       CPCNRC - Draws black and white contours with a single call.  Simulates
31       the behavior of the old routine CONREC; it has the same arguments and
32       produces similar output.
33
34       CPEZCT - Draws black and white contours with a single call.  Simulates
35       the behavior of the old subroutine EZCNTR in Conrec_family; it has the
36       same arguments and will produce similar output.
37
38       CPGETC - Retrieves the current value of an internal parameter of type
39       CHARACTER.
40
41       CPGETI - Retrieves the current value of an internal parameter of type
42       INTEGER.
43
44       CPGETR - Retrieves the current value of an internal parameter of type
45       REAL.
46
47       CPLBAM - Adds label boxes (for the informational label, high and low
48       labels, and contour-line labels) to an area map. The ultimate object of
49       this will usually be to prevent contour lines drawn by CPCLDM from
50       passing through labels or to prevent fill of the label boxes as contour
51       bands are filled.
52
53       CPLBDR - Draws labels (an informational label, high and low labels, and
54       line labels).
55
56       CPMVIW - Moves the contents of an old integer workspace to a new one.
57
58       CPMVRW - Moves the contents of an old real workspace to a new one.
59
60       CPPKCL - Picks a set of contour levels.
61
62       CPPKLB - Picks a set of labels for labeled contour levels.
63
64       CPRECT - Initializes the contouring of a rectangular array of data.
65
66       CPRSET - Resets all parameters to their initial default values.
67
68       CPSETC - Sets the value of an internal parameter of type CHARACTER.
69
70       CPSETI - Sets the value of an internal parameter of type INTEGER.
71
72       CPSETR - Sets the value of an internal parameter of type REAL.
73
74       CPSPS1 - Interpolates from an array of data on a "sparse" rectangular
75       grid which is regularly spaced in X and Y to an array of data on a
76       "dense" rectangular grid and to initialize contouring from the array on
77       the dense grid. (By a "sparse" grid is meant one whose dimensions are
78       smaller than one would like, so that contour lines constructed directly
79       on it are composed of long straight segments.) CPSPS1 may be viewed as
80       a data smoothing routine.
81
82       CPSPS2 - Interpolates from an array of data on a "sparse" rectangular
83       grid which is irregularly spaced in X and Y to an array of data on a
84       "dense" rectangular grid and to initialize contouring from the array on
85       the dense grid. (By a "sparse" grid is meant one whose dimensions are
86       smaller than one would like, so that contour lines constructed directly
87       on it are composed of long straight segments.) CPSPS2 may be viewed as
88       a data smoothing routine.

ACCESS

134       libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
135

MESSAGES

137       Various error conditions can occur in Conpack.  Each of these results
138       in a call to the error-handling routine SETER, with a final argument
139       indicating that the error is recoverable; by default, an error message
140       is printed and execution is terminated, but, if you turn on error
141       recovery (as described in the "man" page for "error_handling"), you can
142       get control back.
143
144       The error messages are as follows:
