NAME¶

Softfill - Fills a polygonal subset of the plotter frame.

SYNOPSIS¶

SFSGFA - Can be made to fill polygons by calling the GKS routine GFA or by calling the lower-level Softfill routines SFWRLD and SFNORM. SFWRLD - Fills polygons with parallel lines or with dots, polymarkers, or selected characters arrayed in a regular rectangular pattern. SFNORM - Fills polygons with parallel lines or with dots, polymarkers, or selected characters arrayed in a regular rectangular pattern. SFGETC - Retrieves the current character value of a specified internal parameter. SFGETI - Retrieves the current integer value of a specified internal parameter. SFGETP - Retrieves the current value of the dot pattern. SFGETR - Retrieves the current real value of a specified internal parameter. SFSETC - Sets the new character value of a specified internal parameter. SFSETI - Sets the new integer value of a specified internal parameter. SFSETP - Sets the new value of the dot pattern. SFSETR - Sets the new real value of a specified internal parameter.

MESSAGES¶

Various error conditions can occur in Softfill. Each of these results in a call to the error-handling routine SETER, with a final argument indicating that the error is recoverable; by default, an error message is printed and execution is terminated, but, if you turn on error recovery (as described in the "man" page for "error_handling"), you can get control back. The error messages are as follows; all should be more or less self-explanatory.
SFGETC - PARAMETER NAME NOT KNOWN - X SFGETC - PARAMETER NAME TOO SHORT - X SFGETC - UNCLEARED PRIOR ERROR SFGETI - UNCLEARED PRIOR ERROR SFGETP - UNCLEARED PRIOR ERROR SFGETR - PARAMETER NAME NOT KNOWN - X SFGETR - PARAMETER NAME TOO SHORT - X SFGETR - UNCLEARED PRIOR ERROR SFNORM - ARRAY DST IS TOO SMALL SFNORM - ARRAY IND IS TOO SMALL SFNORM - COORDINATE ARRAYS TOO SMALL SFNORM - LOGIC ERROR - SEE SPECIALIST SFNORM - UNCLEARED PRIOR ERROR SFSETC - PARAMETER NAME NOT KNOWN - X SFSETC - PARAMETER NAME TOO SHORT - X SFSETC - UNCLEARED PRIOR ERROR SFSETI - UNCLEARED PRIOR ERROR SFSETP - UNCLEARED PRIOR ERROR SFSETR - PARAMETER NAME NOT KNOWN - X SFSETR - PARAMETER NAME TOO SHORT - X SFSETR - UNCLEARED PRIOR ERROR SFSGFA - ERROR EXIT FROM GQFACI SFSGFA - ERROR EXIT FROM GQPLCI SFSGFA - UNCLEARED PRIOR ERROR SFWRLD - UNCLEARED PRIOR ERROR
The "LOGIC ERROR" in SFNORM should never occur; if it does, it indicates a compiler problem or some sort of tampering with the code of the package. Error messages that complain of an error exit from a GKS routine probably imply that GKS has somehow been put in the wrong state. In the messages that result from using an incorrect internal-parameter name in a call to one of the parameter-access routines, the "X" will be replaced by the offending name.
