SYNOPSIS
subroutine rect(xpage,ypage,height,width,angle,ipen)
DESCRIPTION
RECT is a FORTRAN subroutine used to draw rectangles.
OPTIONS
XPAGE,YPAGE are the coordinates, in inches, of the rectangle’s lower left corner, before rotation. HEIGHT is the rectangle’s height, in inches. WIDTH is the rectangle’s width, in inches. (This parameter defines the base of the rectangle.) ANGLE is the angle, in degrees, at which the rectangle’s base is to be drawn. (Rectangle is rotated about XPAGE,YPAGE.) IPEN is the code that moves the pen to the rectangle’s starting point. If the value of IPEN is:
3, the pen is up for the move; 2, the pen is down for the move.
EXAMPLES
Sample program:
program demo_rect use M_calcomp, only : plots, plot, newpen, rect use M_calcomp, only : END,MOVE implicit none real :: xmax=8.5,ymax=7.0 real :: xstart=2.5, ystart=1.0 ! lower left corner before rotation real :: height=3.0, wdth=5.0 real :: angle call plots(0.0,xmax,0.0,ymax) ! (make a small dot at xstart,ystart> call rect(xstart,ystart,0.04,0.04,45.0,MOVE) ! rectangle call newpen(1) angle=0.0 call rect(xstart,ystart,height,wdth,angle,MOVE) ! rotated rectangle angle=45.0 call newpen(2) call rect(xstart,ystart,height,wdth,angle,MOVE) ! end graphics call plot(0.0,0.0,END) end program demo_rect
