.SH NAME
Softfill - Fills a polygonal subset of the plotter frame.
.SH 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.
.sp
SFWRLD - Fills polygons with parallel lines or with dots,
polymarkers, or selected characters arrayed in a regular
rectangular pattern.
.sp
SFNORM - Fills polygons with parallel lines or with dots,
polymarkers, or selected characters arrayed in a regular
rectangular pattern.
.sp
SFGETC - Retrieves the current character value of a specified
internal parameter. 
.sp
SFGETI - Retrieves the current integer value of a specified
internal parameter.
.sp
SFGETP - Retrieves the current value of the dot pattern.
.sp
SFGETR - Retrieves the current real value of a specified
internal parameter.
.sp
SFSETC - Sets the new character value of a specified internal
parameter.
.sp
SFSETI - Sets the new integer value of a specified internal
parameter.
.sp
SFSETP - Sets the new value of the dot pattern.
.sp
SFSETR - Sets the new real value of a specified internal
parameter.

.SH 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.
.sp
The error messages are as follows; all should be
more or less self-explanatory.

.sp
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.
