C*PGQHS -- inquire hatching style C%void cpgqhs(float *angle, float *sepn, float* phase); C+ SUBROUTINE PGQHS (ANGLE, SEPN, PHASE) REAL ANGLE, SEPN, PHASE C C Query the style to be used hatching (fill area with fill-style 3). C C Arguments: C ANGLE (output) : the angle the hatch lines make with the C horizontal, in degrees, increasing C counterclockwise (this is an angle on the C view surface, not in world-coordinate space). C SEPN (output) : the spacing of the hatch lines. The unit spacing C is 1 percent of the smaller of the height or C width of the view surface. C PHASE (output) : a real number between 0 and 1; the hatch lines C are displaced by this fraction of SEPN from a C fixed reference. Adjacent regions hatched with the C same PHASE have contiguous hatch lines. C-- C 26-Feb-1995 - new routine [TJP]. C 19-Jun-1995 - correct synopsis [TJP].
