     defpattern(3G)                                     defpattern(3G)



     NAME

          defpattern - defines patterns


     SPECIFICATION

          C         defpattern(n, size, mask)

                    short n, size;

                    short *mask;




          FORTRAN   subroutine defpat(n, size, mask)

                    integer*4 n, size

                    integer*2 mask((size*size)/16)


     DESCRIPTION

          defpattern defines an arbitrary pattern.  n specifies an

          index into a table of patterns.  size specifies the size of

          the pattern: 16, 32, or 64 for a 16x16-, 32x32-, or 64x64-

          bit pattern, respectively.  mask is an array of shorts that

          form the actual bit pattern.  The pattern is described from

          left to right and bottom to top, just as characters are

          described in a raster font.  By default, pattern 0 is a

          16x16 solid pattern that cannot be changed.  There is no

          performance penalty for non-solid patterns.
