Introduction
Introduction
You now have the opportunity to utilize your artistic talents without the mess of
paints and bother of stretching canvas. Art Gallery gives you the freedom to
create pictures with your video display as the canvas, the keyboard as your palette,
and the cursor
as your brush.
Leonardo da Vinci, Vincent van Gogh, and Henri Matisse would surely be jealous
if they could see you using your Color Computer to create masterpieces. And your
art can be preserved in your own personal art gallery -in the form
of acassette
tape.
For those with aAK or 16K Color Computer, Art Gallery lets you draw color
images on the screen and save them on tape for later touchups and viewing. (You
do
not have to have acassette recorder to use Art Gallery, but you cannot save
art for later viewing without one.) You can also type block letters in the size you
choose and view those later.
Also,
if you have a16K Color Computer you have atext editing screen, where you
type
text in your choice of size and then have it scroll horizontally or vertically.
If you have drawn apicture in the DRAW OR CHANGE PICTURE section, the
message you write in
EDIT TEXT AND CONTROLS will be scrolled across the
picture. This way you can make graphics with captions for public or private presen-
tations. These presentations can be stored on tape and shown later.

The Art Gallery Data Tape
The Data tape, included as part of the Art Gallery package, should give you an
idea
of the versatility you have in drawing and storing your finished "attempts".
Unfortunately, those without acassette player cannot view the Data tape.
Make sure that your cassette player is properly connected to your Color
Computer. Insert
the cassette in the recorder and rewind the tape.

Loading the Program (continued)
If you have a4K Color Computer, you will have to load the Data tape presenta-
tion one picture at atime. Press rn
at the Menu.
The screen will show:
PREPARE RECORDER TO PLAY
PUSH "ENTER" WHEN READY
(OR "BREAK" TO GO BACK TO MENU)
Press (ENTER) and the screen will show: LOAD ING (with an @sign at the bottom
of the screen). After the picture is loaded, the Menu will return. Press CD to
see the picture. After the first picture has been viewed, press (BREAK) to return
to the Menu. Repeat this process until you have seen all 27 pictures on the Data
tape. The 27 images on
the Data tape are listed in Appendix Bon page 21.
If you have a16K Color Computer, you should refer to the last instruction,
6
LOAD & RUN PRESENTATION. Using this procedure, all of the images
are displayed without interruption. Those with a16K Color Computer have
the
option of using 3 LOAD FROM TAP E to view the Data tape pictures one at a
time.
After
you finish learning the key functions of Art Gallery, see Appendix Ato
find how
to use the Data tape to experiment with the key functions.
The Template
Atemplate is provided with key labels to help you locate and memorize the
various functions of Art Gallery. Place the overlay on the keyboard.
