plpat: Set area fill pattern

Sets the area fill pattern. The pattern consists of 1 or 2 sets of parallel lines with specified inclinations and spacings. The arguments to this routine are the number of sets to use (1 or 2) followed by two pointers to integer arrays (of 1 or 2 elements) specifying the inclinations in tenths of a degree and the spacing in micrometers. (also see plpsty)

nlin (PLINT, input) Number of sets of lines making up the pattern, either 1 or 2. inc (PLINT *, input) Pointer to array with nlin elements. Specifies the line inclination in tenths of a degree. (Should be between -900 and 900). del (PLINT *, input) Pointer to array with nlin elements. Specifies the spacing in micrometers between the lines making up the pattern.

Redacted form:

• General: plpat(inc, del)

• Perl/PDL: plpat(nlin, inc, del)
