Name: PGRECT Purpose: draw a rectangle, using fill-area attributes Category: GRAPHICS File: pgplot.src Author: T.J. Pearson Use: see description below. Description: SUBROUTINE PGRECT (X1, X2, Y1, Y2) REAL X1, X2, Y1, Y2 This routine can be used instead of PGPOLY for the special case of drawing a rectangle aligned with the coordinate axes; only two vertices need be specified instead of four. On most devices, it is faster to use PGRECT than PGPOLY for drawing rectangles. The rectangle has vertices at (X1,Y1), (X1,Y2), (X2,Y2), and (X2,Y1). Arguments: X1, X2 (input) : the horizontal range of the rectangle. Y1, Y2 (input) : the vertical range of the rectangle. Updates: Oct 16, 1998: JPT automatically extracted from source.
