Name: PGPAP

Purpose: change the size of the view surface

Category: GRAPHICS

File: pgplot.src

Author: T.J. Pearson

Use: see description below.

Description:

SUBROUTINE PGPAP (WIDTH, ASPECT)
REAL WIDTH, ASPECT

This routine changes the size of the view surface ("paper size") to a
specified width and aspect ratio (height/width), in so far as this is
possible on the specific device. It is always possible to obtain a
view surface smaller than the default size; on some devices (e.g.,
printers that print on roll or fan-feed paper) it is possible to
obtain a view surface larger than the default.

This routine should be called either immediately after PGBEG or
immediately before PGPAGE. The new size applies to all subsequent
images until the next call to PGPAP.

Arguments:
WIDTH (input) : the requested width of the view surface in inches;
if WIDTH=0.0, PGPAP will obtain the largest view
surface available consistent with argument ASPECT.
(1 inch = 25.4 mm.)
ASPECT (input) : the aspect ratio (height/width) of the view
surface; e.g., ASPECT=1.0 gives a square view
surface, ASPECT=0.618 gives a horizontal
rectangle, ASPECT=1.618 gives a vertical rectangle.
