NAME

6       Softfill - Fills a polygonal subset of the plotter frame.
7

SYNOPSIS

9       SFSGFA - Can be made to fill polygons by calling the GKS routine GFA or
10       by calling the lower-level Softfill routines SFWRLD and SFNORM.
11
12       SFWRLD - Fills polygons with parallel lines or with dots, polymarkers,
13       or selected characters arrayed in a regular rectangular pattern.
14
15       SFNORM - Fills polygons with parallel lines or with dots, polymarkers,
16       or selected characters arrayed in a regular rectangular pattern.
17
18       SFGETC - Retrieves the current character value of a specified internal
19       parameter.
20
21       SFGETI - Retrieves the current integer value of a specified internal
22       parameter.
23
24       SFGETP - Retrieves the current value of the dot pattern.
25
26       SFGETR - Retrieves the current real value of a specified internal
27       parameter.
28
29       SFSETC - Sets the new character value of a specified internal
30       parameter.
31
32       SFSETI - Sets the new integer value of a specified internal parameter.
33
34       SFSETP - Sets the new value of the dot pattern.
35
36       SFSETR - Sets the new real value of a specified internal parameter.

MESSAGES

55       Various error conditions can occur in Softfill.  Each of these results
56       in a call to the error-handling routine SETER, with a final argument
57       indicating that the error is recoverable; by default, an error message
58       is printed and execution is terminated, but, if you turn on error
59       recovery (as described in the "man" page for "error_handling"), you can
60       get control back.
61
62       The error messages are as follows; all should be more or less self-
63       explanatory.
64
65            SFGETC - PARAMETER NAME NOT KNOWN - X
66            SFGETC - PARAMETER NAME TOO SHORT - X
67            SFGETC - UNCLEARED PRIOR ERROR
68            SFGETI - UNCLEARED PRIOR ERROR
69            SFGETP - UNCLEARED PRIOR ERROR
70            SFGETR - PARAMETER NAME NOT KNOWN - X
71            SFGETR - PARAMETER NAME TOO SHORT - X
72            SFGETR - UNCLEARED PRIOR ERROR
73            SFNORM - ARRAY DST IS TOO SMALL
74            SFNORM - ARRAY IND IS TOO SMALL
75            SFNORM - COORDINATE ARRAYS TOO SMALL
76            SFNORM - LOGIC ERROR - SEE SPECIALIST
77            SFNORM - UNCLEARED PRIOR ERROR
78            SFSETC - PARAMETER NAME NOT KNOWN - X
79            SFSETC - PARAMETER NAME TOO SHORT - X
80            SFSETC - UNCLEARED PRIOR ERROR
81            SFSETI - UNCLEARED PRIOR ERROR
82            SFSETP - UNCLEARED PRIOR ERROR
83            SFSETR - PARAMETER NAME NOT KNOWN - X
84            SFSETR - PARAMETER NAME TOO SHORT - X
85            SFSETR - UNCLEARED PRIOR ERROR
86            SFSGFA - ERROR EXIT FROM GQFACI
87            SFSGFA - ERROR EXIT FROM GQPLCI
88            SFSGFA - UNCLEARED PRIOR ERROR
89            SFWRLD - UNCLEARED PRIOR ERROR
90
91       The "LOGIC ERROR" in SFNORM should never occur; if it does, it
92       indicates a compiler problem or some sort of tampering with the code of
93       the package.  Error messages that complain of an error exit from a GKS
94       routine probably imply that GKS has somehow been put in the wrong
95       state.  In the messages that result from using an incorrect internal-
96       parameter name in a call to one of the parameter-access routines, the
97       "X" will be replaced by the offending name.
