deflin(3G)deflin(3G)NAMEdeflin - defines a linestyle
FORTRAN 77 SPECIFICATION
subroutine deflin(n, ls)
integer*4 n, ls
PARAMETERS
n expects the constant that you want to use as an identifier for the
linestyle described by ls. This constant is used as an index into a
table of linestyles. By default, index 0 contains the pattern $FFFF,
which draws solid lines and cannot be redefined.
ls expects a 16-bit pattern to use as a linestyle. This pattern is
stored in the linestyle table at index n. You can define up to 65536
distinct linestyles.
DESCRIPTIONdeflin defines a linestyle that is a write-enabled pattern applied when
lines are drawn. The least-significant bit of the linestyle is applied
first. Use setlin to select a linestyle for use. The selected linestyle
is sometimes referred to as the current linestyle.
SEE ALSO
defcur, defpat, defras, getlst, lsrepe, setlin
NOTES
This routine is available only in immediate mode.
On the Personal Iris, there is a performance penalty for drawing non-
solid lines; there is no penalty on the other IRIS-4D models.
When deflin is used to modify the current linestyle, the new linestyle
becomes current only when setlin is called again.
