Selects a pattern for filling polygons and rectangles.
FORTRAN (libfgl.a)
void setpattern(Int32 index)
SUBROUTINE SETPAT(index) INTEGER*4 index
The setpattern subroutine selects a pattern from a table of patterns previously defined by the defpattern subroutine. The pattern, an area-fill attribute, is used whenever an area-fill primitive is invoked. These primitives include filled polygons, rectangles, circles, and arcs.
The default pattern is 0 (zero), which is solid. If you specify an undefined pattern, the default pattern is selected.
Note: The operation of this subroutine for the Supergraphics Processor Subsystem is modified. ( See "Hardware Considerations".)
| index | Specifies the index into the table of defined patterns. |
