NAME

6       plspage - Set page parameters
7

SYNOPSIS

9       plspage(xp, yp, xleng, yleng, xoff, yoff)
10

DESCRIPTION

12       Sets  the page configuration (optional).  If an individual parameter is
13       zero then that parameter value is not updated.  Not all parameters  are
14       recognized  by  all drivers and the interpretation is device-dependent.
15       The X-window driver uses the length and offset parameters to  determine
16       the  window  size  and  location.   The  length  and  offset values are
17       expressed in units that  are  specific  to  the  current  driver.   For
18       instance:  screen drivers will usually interpret them as number of pix‐
19       els, whereas printer drivers will usually use mm.
20
21       This routine, if used, must be called before initializing  PLplot.   It
22       may be called at later times for interactive drivers to change only the
23       dpi for subsequent redraws which you can force  via  a  call  to  plre‐
24       plot(3plplot).   If  this  function  is  not  called then the page size
25       defaults to landscape A4 for drivers which use real  world  page  sizes
26       and  744 pixels wide by 538 pixels high for raster drivers. The default
27       value for dx and dy is 90 pixels per inch for raster drivers.

31       This function is used in examples 14 and 31.

ARGUMENTS

34       xp (PLFLT(3plplot), input)
35              Number of pixels per inch (DPI), x. Used only by raster drivers,
36              ignored by drivers which use "real world" units (e.g. mm).
37
38       yp (PLFLT(3plplot), input)
39              Number  of  pixels per inch (DPI), y.  Used only by raster driv‐
40              ers, ignored by drivers which use "real world" units (e.g. mm).
41
42       xleng (PLINT(3plplot), input)
43              Page length, x.
44
45       yleng (PLINT(3plplot), input)
46              Page length, y.
47
48       xoff (PLINT(3plplot), input)
49              Page offset, x.
50
51       yoff (PLINT(3plplot), input)
52              Page offset, y.
