HOW
TO
USE THE RASTERIZER
HOW TO USE THE RASTERIZER
Using the Tektronix 4510
Rasterizer,
you can copy the graphics area to a 4691 or
4692 Copier with greater resolution than when copying directly from the screen to
the
copier.
The Rasterizer also gives you a wider color selection.
You can use the Rasterizer only on images that were created as segments
.
If you
aren 't sure of what a segment
is,
you may want to refer to Exercise
4:
Creating
Graphics in Section
2.
If the image was not created as
segments,
you can use
Setup commands to display the image as a segment (explained below)
.
Follow these steps for making a rasterized
copy:
1.
Be sure the Rasterizer is connected to the terminal
,
the color copier is
connected to the Rasterizer, and all are powered on
.
(Appendix
A tells you
how to connect the Rasterizer and a color copier.)
These procedures assume the Rasterizer is connected to PORT
0.
If it is
connected to PORT
1,
substitute P1
:
wherever
PO:
is shown in a command.
2.
Put the terminal in Setup
,
if it isn 't
already.
3.
Be sure the dialog area is enabled so your commands won 't clutter the
graphics:
DAENABLE YES
4.
Display your image and be sure it is comprised of segments
.
If your host program does not display graphics as segments
,
you can make a
segment out of the entire display by opening a segment before the host
displays the graphics
,
then closing the segment after the graphics are drawn
.
Like this:
a.
Open a segment (in this case, Segment 1) by entering
:
SGOPEN 1
b.
Take the terminal out of Setup
.
c.
Enter the commands required by your host to display graphics on the
terminal.
d.
After the image is on the screen
,
return the terminal to Setup.
e.
Close the segment by entering
:
SGCLOSE
5.
Make sure your image is in the current view.
3-20
If you have more than one view on the screen
,
the image in the current view
will be sent to the
Rasterizer.
Refer to Exercise
6:
Using the Zoom/Pan
Function in Section 2 of this manual for instructions on entering the Zoom and
Pan function
,
selecting views
,
and returning to Setup
.
