5 D p f s
There are two escape sequences to define the area (or picture frame) that can
be used for GL/2 graphics:
i n
which n is the horizontal size of the picture frame in decipoints, and
<ESC>
'kCH
Y
in which n is the vertical size of the picture frame in decipoints.
These commands have the following side-effects: they set P 1to the lower left
corner and P2 to the upper right corner of the picture frame. set the soft
clipping window to coincide with the picture frame, clear the polygon buffer,
and move the cursor to P 1.
If n in either of these commands is zero. the picture frame is set to its default
size.
5 P f a p
This command sets the location of the Picture Frame anchor point, the
position of the upper left corner of the picture frame.
<ESC>
*C 77
T
When
i7
is set to 0, the picture frame anchor point is set to the current point.
When it is other than O,the anchor point is set to the upper left corner of the
current logical page.
Side-effects of this command are that it sets P1 to the lower left corner and
P2 to the upper right corner of the picture frame, it sets the soft clipping
window to coincide with the picture frame, it clears the polygon buffer, and
it moves the cursor to P1.
