ALPHA PLOT INSTRUCTIONS
-----------------------
GENERAL INFORMATION
-------------------
Alpha Plot is a sophisticated Hi-Res graphics program that
will let you flex your Apple's Hi-Res capabilities to create
colorful drawings and detailed charts and graphs. These
instructions will do their best job if you run Alpha Plot
and experiment while you read. Most of the details not in
the instructions are printed on the screen.
ALPHA INFO
----------
Any changes or suggestions that we have come up with since
this book was printed appear on the Alpha Plot disk. Run
the "Alpha Info" program.
ALPHA PLOT'S TWO MODES
----------------------
Alpha Plot features a Drawing Mode and a Typing Mode. To
enter either mode, select Key Chart Option 4, then D or T,
OR type ctrl-D or ctrl-T while typing or drawing. In the
Drawing Mode, you can do everything EXCEPT type. Typing
Mode lets you type and access Options 1-6.
TWO IMAGE PAGES
---------------
The Apple has two Hi-Resolution screens or "Pages", called
Page 1 and Page 2. With Alpha Plot, you can store two
images in memory at the same time and view either one.
Alpha Plot lets you draw or type only on Page 1, but you may
easily move images from Page 1 to Page 2 and back, and from
memory to disk and back from or to either page. You may,
of course, store as many images as you want on disk.
APPLE'S SCREEN LAYOUT
---------------------
Apple's Hi-Res screens measure 280 plots wide (0-279) by 192
plots high (0-191). Four colors (1,2,5,6), two blacks (0,4)
and two whites (3,7) are available for Hi-Res plotting. See
"<1> Color Selection" and your Applesoft Manual and for more
information.
CURSOR MOVES
------------
Cursor moves from the Drawing and Typing Modes are similar.
From the Typing Mode, you must press the CTRL key WHILE you
press the appropriate cursor-move key. Otherwise, you would
type the letter on the screen.
KEY DIRECTION AMOUNT
L. Arrow Left 1 unit
(ctrl)-K Left 1 plot
R. Arrow Right 1 unit
(ctrl)-L Right 1 plot
(ctrl)-A Up 1 unit
(ctrl)-S Up 1 plot
(ctrl)-Z Down 1 unit
(ctrl)-X Down 1 plot
See more about units, plots, and other cursor-move features
in the Typing Mode and Drawing Mode sections. The Alpha
Plot key layout works well for comfortable two-hand
operation. Notice that the plot-move keys are adjacent to
the unit-move keys.
<RETURN>
--------
If you find yourself in a part of Alpha Plot you don't want
to be in (for example, you might accidentally press a 5 and
be in the "Erase the Screen" mode), pressing the <RETURN>
key as an answer to a question will usually get you back to
the Drawing or Typing mode.
COMPATIBILITY WITH NORMAL DISKS
-------------------------------
Images created with Alpha Plot are completely compatible
with your normal programs and disks. Therefore, you may use
pictures made with Alpha Plot in your own programs. Run and
list the program on the Alpha Plot disk called "PICTURE
BLOAD DEMO" if you are unfamiliar with loading and viewing
hi-res pictures under program control.
SAVE TO BE SAFE
---------------
Making a drawing on your Apple is quite a bit like
programming. The more you plan, the better things turn out.
The more you practice, the more efficient you will be. As
with programming, SAVE YOUR WORK from time to time in case
you want to continue drawing from where you were ten minutes
ago (or in case the dog pulls the plug).
STARTING OUT
------------
Boot the Alpha Plot disk, and choose the "Run Alpha Plot"
option. Answer Y to "Clear the Hi-Res screen?" (or answer N
if you have pictures in memory that you want to keep).
After the usual amount of disk-whirring, you will be
presented with Hi-Res Page 1, with text at the bottom of the
screen offering you the choices D, T, L and S for Draw,
Type, Load and Save. You will re-encounter this portion of
the program each time you press the 4 key. More later about
that.
DRAWING MODE
------------
From this mode you can do anything except type--plot lines,
dots, ellipses and boxes, and perform page and image
manipulations.
MOVING THE CURSOR
-----------------
When you first run Alpha Plot, you will see a flickering
squarish dot on the screen. This is the XO CURSOR, actually
four cursors in one. Press the A, Z and Arrow keys a few
times to separate the four cursors and to get a feel for
cursor movement. Try the K, L, S and X keys too for
one-plot movement. Notice how the O part of the cursor is
controlled by you while the X stays in one position, and the
two dots go along for the ride.
CURSOR JUMPS
------------
How far your cursor goes with each keypress is determined by
the SPEED (9 key). However, you may JUMP the cursor 50
PLOTS without changing the speed. Simply press <ESC>, then
A, Z, or an Arrow. To jump 150 plots down from the top of
the screen, for example, type <ESC>-Z-<ESC>-Z-<ESC>-Z.
CURSOR COORDINATES and OFFSET
-----------------------------
At the bottom left of the screen is information regarding
the current position of the cursor. The H and V values
after the word "CURSOR" represent the horizontal and
vertical coordinates of the O part of the cursor. The
"OFFSET" values represent the horizontal and vertical
distances BETWEEN the X and the O. Notice that coordinates
H=O and V=O place the cursor at the upper left of the screen
and coordinates H=279 and V=191 place it at the lower right.
(NOTE: To exit the Drawing Mode, type "4" or ctrl-T.)
THE KEYS
--------
Except for cursor moves, most Alpha Plot features are
controlled by the top row of keys as indicated on your
Keyboard Chart. Here is a discussion of each key and what
it does.
(SPACE BAR) DRAW/MOVE SELECTION
-------------------------------
Press the space bar and you will see the flashing word,
"DRAW", on the top left text line. Now move your cursor and
it will indeed draw. Press the space bar again and "DRAW"
will change to "MOVE", meaning you can move the cursor
without drawing. The space bar is used because it is easily
reachable with your thumb while you are manipulating the
cursor. to plot a single dot, press the space bar twice and
move the cursor away.
(RETURN) ZERO OFFSET
--------------------
Pressing the <Return> key while you are in the Drawing Mode
will set the offset to Zero and place all four corners of
the XO Cursor on top of the O. This same feature is
accomplished by pressing 8 and Z. See "<B> Modify Cursor".
(1) COLOR
---------
Press the 1 key and you can select your Drawing or Typing
(size>1) color. If Alpha Plot isn't drawing or typing when
you think it should be, maybe you have the drawing color set
the same as your background. To select a new color quickly,
simply type 1-3 or 1-6 or 1-whatever, depending on the color
you want.
COLOR BUGS
----------
1. The Apple won't let you draw certain colors in certain
vertical columns. You can only draw in Colors 1 and 5 in
ODD-NUMBERED columns. Alpha Plot corrects this by moving
the cursor one plot over when necessary.
2. A WHITE VERTICAL line will appear in color unless you
plot another line directly next to it. Alpha Plot does this
for you for Colors 4 (Black) and 7 (White), but NOT for
Colors 0 (Black) and 3 (White). That way you have a choice
when drawing vertical lines.
SPECIAL COLORS: 8 & 9
----------------------
COLOR #8 (REVERSE) lets you draw lines or boxes (not
ellipses) in the OPPOSITE of the background color. These
lines and boxes may be erased by re-drawing over them in
Reverse. Experiment and see.
COLOR #9 (MIX) lets you select TWO COLORS (not Reverse) for
drawing filled boxes and ellipses. Every other horizontal
line will appear in each color. You can create many
different shades and hues by mixing colors (and by adjusting
a few of the knobs on your T.V. set!). Load the "Color
Chart" picture from the Alpha Plot disk to see the range of
color possibilities. If your color is #9 (mix), your
drawing color for lines will be the FIRST COLORS of the
mix.
(2) NOTES
----------
The notes at the bottom of the screen may be turned off to
reveal whatever image may be behind the notes. Press 2 for
full-screen graphics or to turn the notes back on again.
(3) GRID
---------
Press 3 to draw a Hi-Res grid over your picture. Press 3
again and the grid will be erased (that's Color #8 again!).
There are dots at every ten plots in both directions. The
grid lines are 100 plots apart. It is best NOT to draw or
type with the grid on the screen unless you want the grid as
a permanent part of your picture. When the grid erases, it
will draw little dots and stripes on any NEW parts of your
drawing. Another way to access the grid is to draw it on
Page 1 and store it on Page 2 (see option 6).
(4) DRAW, TYPE, LOAD & SAVE
----------------------------
Running Alpha Plot or selecting Key Chart Option 4 will get
you into the "Draw, Type, Load, Save" mode with its animated
text arrow. the Drawing Mode and Typing Modes (described
earlier) may be entered from this option by selecting "D" or
"T".
"Load" and "Save", selectable by pressing the L or S keys,
let you load and save (actually BLOAD and BSAVE) hi-res
pictures to and from disk. Hi-res pictures will usually
appear as 34 sector binary (B) files in your catalogs.
Scrunched picture files (see page 38) will be smaller.
You may catalog whatever disk is in your drive by first
selecting L or S and then typing "CAT" (return) when a file
name is requested. You cannot perform other DOS functions
such as Lock and Unlock while using Alpha Plot. To resave a
picture that is locked, save it with a different name OR
save it onto another disk. If you want, you can even quit
Alpha Plot and load and save hi-res images "by hand" by
typing:
BLOAD PICTURE, A$2000 (page 1)
BLOAD PICTURE, A$4000 (page 2)
BSAVE PICTURE, A$2000, L$2000 (page 1)
BSAVE PICTURE, A$4000, L$2000 (page 2)
The "PICTURE BLOAD DEMO" program demonstrates more regarding
handling of hi-res pictures.
ERRORS
------
If the disk is full or some other error occurs during a Load
or Save, you will see an error message number on the screen
and the program will continue. the error number represents
the TYPE of error that has occurred. Here are the most
likely numbers: 4=WRITE PROTECTED, 6=FILE NOT FOUND, 8=I/O
ERROR, 9=DISK FULL, 10=FILE LOCKED, 13=FILE TYPE MISMATCH.
See your Applesoft Manual for the complete list. If you are
attempting to save an image and get a DOS error, such as
"File Type Mismatch" or "Disk Full", your picture will NOT
BE SAVED completely. You will need to exit Alpha Plot,
correct the problem, Run Alpha Plot, and save your image
again.
(5) CLEAR THE SCREEN
--------------------
Press 5 and select the color you want to clear the screen.
Your picture will be permanently erased unless you pick
"Color" #8 which will give you a NEGATIVE IMAGE of the
screen. "Erase" again with Color #8 and you'll get your own
positive image back!
(6) IMAGE OPTIONS
-----------------
Pressing 6 gives you four powerful options:
(6-P) SEE PAGE 2:
-----------------
Press P, and you will see your Page 2 image (if there is
one). Now press any key, and the screen will flicker
between Pages 1 and 2 so you may compare them. Press any
key again, and you are back to Page 1.
(6-S) SWITCH IMAGES:
--------------------
Press S and your two pages will be switched. Now you can
draw or type on your (former) Page 2 image.
(6-R) RELOCATE:
---------------
Any rectangular section of Page 1 may be duplicated on
either page within the limits of the screen. BEFORE YOU
SELECT OPTION 6-R, define the area to be moved with the four
points of the XO cursor. Now press 6 and R, select 1 or 2
for the page you want the move made to and move the flashing
rectangle to the desired new location. The 2 key will
function here if you want to temporarily remove the screen
notes. PRESS M TO MAKE THE TRANSFER or <Return> to escape.
After the transfer has been made, you may delete the
original section image by drawing a solid box over it.
(6-M) MERGE PAGES:
------------------
Alpha Plot lets you merge pictures four different ways. If
you're into the terminology ("A OR B", etc.), here it is.
If you're not, ignore this:
1. A OR B (Opaque Non-Black Page 1 onto Page 2)
2. A EOR B (XDraw Page 1 onto Page 2)
3. A AND B (Opaque Black Page 1 onto Page 2)
4. A=B ( Compare/Combine)
You will want to experiment with each option. If your Page
2 picture is valuable, SAVE IT on disk BEFORE MERGING. Here
are two sample images. The four possible merges appear on
the next page.
PAGE 1 BEFORE MERGE (PICTURES GO HERE)
(7) KEYBOARD/PADDLE SWITCH
--------------------------
The 7 key will switch cursor control from paddles to
keyboard and back with a "KEY" or "PDL" appearing on the top
line of the screen notes. If you don't have paddles, you
don't need paddles; keyboard control is far more accurate.
Paddle-1 will move it vertically. Paddles have no effect in
the Typing Mode. All keys except the cursor-move keys have
their normal effect with paddles in control.
(8) MODIFY CURSOR
-----------------
The 8 key lets you select or re-arrange the cursor. The
current cursor's symbol; "XO", "RB", or "--" will appear in
the screen notes.
(8-X) XO CURSOR
----------------
This is the Drawing cursor you will probably use most, since
it is the most versatile of the three available. The XO
cursor consists of four points. The O is the drawing point,
the X is a stationary reference point, and the other two
points assist in the drawing of ellipses, boxes and lines.
Pressing <Return> (or Option 8-Z) or drawing a line (Option
"--") will put all four points on top of the O.
(8-B) RUBBER BAND CURSOR
------------------------
The Rubber Band cursor works similarly to the XO cursor, but
shows you a stretchable projected line between a stationary
point and any other point you select. Using this cursor,
you can actually see a line plot before you draw it.
Pressing <Return> (or Option 8-Z) or drawing a line (Option
"--") will give the Rubber Band a length of zero.
(8-N) NO CURSOR
---------------
The no-cursor mode is used when you want to draw with no
distractions on the screen. With no cursor you can do
everything you can with either of the two visible cursors.
(
8-Z) ZERO OFFSET
-----------------
Z will put all four XO Cursor points on top of the current 0
position, or make the length of the Rubber Band Cursor zero.
Select Z when you want to move the usually stationary X
position. Pressing <Return> from the Drawing Mode is the
same as selection 8-Z.
(8-R) ROTATE LEFT
-----------------
R rotates the XO Cursor points or the Rubber Band 90 degrees
counter-clockwise (unpredictable in PDL mode).
(9) SPEED
---------
Speed determines the NUMBER OF PLOTS the cursor will plot or
move for each A, Z or Arrow keypress. you may select speeds
1-9 by pressing the appropriate number. Pressing a zero
will select a speed of 10. "*" is 20 and "-" is 40. S, X,
K and L will move the cursor 50 PLOTS regardless of the
speed. To quickly select a new speed, simply type 9-5 or
9-* or 9-whatever.
(0) ELLIPSE
-----------
Pressing the Zero key will draw an ellipse that would touch
each of the four sides of an imaginary box connecting the
four XO cursor points. Another Zero will fill the ellipse.
you do not have to wait for the circle to be drawn to fill
it (simply type two zeros). You may halt an ellipse while
it is being drawn by pressing <Return>. An ellipse may be
any color or color mix, but not Reverse. Theoretically, to
draw a CIRCLE, the H and V Offset values at the bottom of
your screen should be about EQUAL. This depends partly on
the amount of distortion on your monitor. Try a test.
(:) BOX
-------
Pressing Colon will draw a linear box connecting the four
points of the XO cursor. Colors 4 and 7 black or white
boxes have fatter vertical sides. Colors 0 and 3 do not
(see "Color Bugs"). A second Colon will fill the box in the
selected color or Reverse. You may use mixed colors for
drawing boxes (see more under Color Selection).
(-) LINE
--------
Pressing a Minus-sign key will connect the X and O ends of
your XO cursor with a line or make an imprint of the Rubber
Band Cursor on the screen in the appropriate color. The
offset will be set to zero at the O end of the cursor. To
erase a Reverse line, simply draw over it in Color #8.
(RESET) QUIT
------------
Hitting Reset OR CTRL -@ will give you the option of exiting
Alpha Plot. Note: With a reset exit, you risk imprinting
the cursor on your picture; no problem if you have already
saved your picture. Alpha Plot erases itself when you quit.
To list it, LOAD it, then LIST.
TYPING MODE
-----------
Alpha Plot lets you type directly onto Page 1 using the
normal set of ASCII characters. There are a few
characteristics you will notice that make Alpha Plot's type
different from the type you are used to seeing on your Apple
screen--
LOWER CASE:
-----------
Whether or not you have lower-case hardware installed in
your Apple, you can type in upper and lower case with Alpha
Plot. The ESC key controls upper and lower case.
SAME-LINE WRAPAROUND:
---------------------
When you reach the edge of the screen while typing in any
direction, the type will jump to the opposite margin, but
stay on the SAME LINE. Use the carriage return when you
reach the edge of the page (as you would on a typewriter) if
you don't want this to happen.
SCREEN POSITION
---------------
Any character may appear at any vertical or horizontal
screen position. There is no connection between Alpha
Plot's type and Apple's HTABS and VTABS. Therefore, you may
adjust the distances between lines and characters, and make
vertical adjustments for subscripts, superscripts and so on.
PROPORTIONAL SPACING
--------------------
With Alpha Plot text, each letter only takes up as much
horizontal space as is necessary. Most characters are the
normal five plots wide. Some, like W's and M's, are wider.
Proportional type is attractive and easy to read, and you
can fit more characters per line on the screen than with
normal type. the only disadvantage comes in backspacing,
and vertical character alignment; a couple of extra
keystrokes are sometimes necessary to align cursors and
characters. Which brings us to--
CURSOR MOVEMENT
---------------
To move the cursor in the typing mode, you must HOLD DOWN
THE CTRL KEY while you press the cursor-move keys. CTRL-A
and CTRL-Z move the cursor up and down one the height of one
line of type (plus leading). The left and right arrows
(ctrl-optional) move the cursor left and right the width of
a normal character (7 plots at normal type size and
kerning). CTRL-S, CTRL-X, CTRL-K and CTRL-L move ONE PLOT
up, down, left and right, allowing you to move to any
precise spot on the screen.
NOTE: To Exit the Typing Mode, hit ctrl-D to draw, or hit
ctrl-O and "4" to draw, load or save.
Ctrl-J: ERASE A SEGMENT
-----------------------
Ctrl-J will erase a letter segment one-plot wide and
one-character high. You must follow each ctrl_J with a
ctrl-K or ctrl-L to advance the cursor left or right.
<ESC> UPPER/LOWER CASE
----------------------
The ESC key will set the upper & lower case switch in three
different positions; 1: Lower Case Only. Position 2 will
produce a capitol letter on the next keystroke and then
switch to lower case operation. The height of the flashing
cursor and the notes at the bottom of the screen will tell
you whether the next character typed will be upper or lower
case.
<CTRL-O> OPTIONS
----------------
Ctrl-O (letter O) will let you select typing options or exit
the Typing Mode.
(Ctrl-O, 1-6)
-------------
Drawing Options 1-6 (on your keyboard Chart) are available
from the Typing Mode AFTER TYPING CTRL-O.
(Ctrl-O, B) BIG COLOR (same as Option 1)
----------------------------------------
You may select the color for type larger than size 1. Due
to the color dot layout of Apple's graphics system,
normal-sized type in color is not readable, so it's not
available on Alpha Plot.
(Ctrl-O, M) MODE
----------------
M changes the type output mode from Inverse to Normal to
Xtype and back. Each Inverse and Normal character clears a
path for itself, so you will always have white or black type
on the opposite color. XTYPE will let you type over your
drawings with the type changing color according to the
background. Color type of size #1 is illegible, so don't
use Xtype over a color background in size 1. Xtype is also
sometimes hard to read when used over complicated
backgrounds.
(Ctrl-O, R) ROTATE TYPING CURSOR
--------------------------------
R allows you to type sideways (good for labeling graphs,
etc.) and upside down (good for people who are upside down).
The cursor points the direction of the type. Carriage
returns and cursor move characteristics are rotated with the
cursor.
(Ctrl-O, S) TYPE SIZES
----------------------
You may type in four type sizes. Every time you press S,
the type size will increase up to type-size #4. Then it
will go back to #1 or normal-size type. You will need to
type a bit slower with type larger than size 1.
(Ctrl-O, L) LEAD
----------------
L controls the vertical distance the cursor is moved for
each carriage return, and thus determines the leading or
space between type lines. Normal leading on the Apple is 1
(and somewhat hard to read). Because of Alpha Plot's lower
case descenders (parts of letters like g's and y's that go
beneath the base line), an extra space of leading is
preferable, so 2 is standard.
(Ctrl-O, K) KERN
----------------
K lets you adjust the kerning or space between characters on
the screen. Normal is 2, but adjust it to suit your
preference, to squeeze more type into a small space or to
stretch a line out to make a title or whatever. On a color
monitor, type kerned one unit could be difficult to read.
POSSIBLE PROBLEMS
-----------------
NO CURSOR
---------
The Drawing or Typing cursor can get hidden behind the
screen notes. Try moving the cursor up, or select Option 2
(or ctrl-O, 2) to remove the notes. You will also have no
cursor if you are in one of the Option modes (top row of
keys). Try hitting <Return>.
THICK VERTICAL LINES
--------------------
Use black or white colors 0 or 4 instead of #3 or #7.
NO PLOT OR TYPE
---------------
Check your plotting color. It could be the same as the
background.
STUCK IN TYPING MODE
--------------------
Press ctrl-O (Options) and select Option 4.
WHICH PAGE AM I LOOKING AT?
---------------------------
usually page 1. The only time you see Page 2 is through
Option 6-P or M. If the screen notes are visible or if you
have a cursor, you are looking at Page 1.
HOW DO I MAKE A PRINTOUT OF MY PICTURE?
---------------------------------------
You need two things-- a printer capable of printing hi-res
AND hi-res "dump" software. Ask your Apple dealer.
CAN I USE DIFFERENT TYPEFACES WITH ALPHA PLOT?
----------------------------------------------
No. You can, however, add different type styles to your
Alpha Plot pictures using other software (Beagle Bros' APPLE
MECHANIC disk, for example).
ALSO ON THE ALPHA PLOT DISK
---------------------------
ALPHA BOOT
----------
This is the program that runs when you boot. It simply
BLOADs Alpha Code, Alpha Plot's machine language programs,
sets the Start of Program pointers to location 24577
($6001), then RUNs Alpha Plot. If you run Alpha Plot and
Alpha Boot hasn't been run, Alpha Plot will run Alpha Boot
for you.
ALPHA CODE
----------
This is the machine language section of Alpha Plot that does
Page switches, superimposing, and so on. I is BLOADed by
Alpha Boot.
ALPHA INFO
----------
Run this program to see the latest changes (if any) since
these instructions were printed.
HI-LO PLOT
----------
This program is fun if you like fooling around with
graphics. the program actually moves Hi-Res image values
form Page 1 ($2000) or page 2 ($4000) down to LO-RES Page 1
($400). What you get is an abstract image of your Hi-Res
picture in Lo-Res. Since the Hi-Res screen is much bigger
than the Lo-Res screen, several versions of the picture are
available. Follow the screen instructions. But first, do
this--
1. Run Hi-Lo Plot.
2. Quit by pressing Q.
3. Load a Hi-Res picture onto Page 1 by typing "HGR" and
"BLOAD FILENAME, A$2000". A good one to use is the
"BBROS LOGO" on the Alpha Plot disk. Load a second
picture onto Page 2 if you want by typing "HGR2" and
"BLOAD FILENAME, A$4000".
4. Type "RUN", and select Option H. Follow the
instructions and let things happen.
5. When you get a picture you like, exit the program with a
Q, and type "BSAVE LO-RES, A$400, L$400".
Now let's convert the picture BACK TO HI-RES. This will
be an abstract of an abstract, not a real conversion.
6. Load the Lo-Res picture you just made onto LO-RES PAGE 2
by typing "BLOAD LO-RES, A$800". We have to use Page 2
because Apple's Text shares Page 1 with Lo-Res.
7. Type "RUN" again.
8. Select Option L. There's your abstract of an abstract!
To save this picture, type "BSAVE HI-RES, A$2000,
L$2000". Keep experimenting. Sooner or later, you'll
come up with some award-winners. The actual Hi-Lo Plot
program is named "^". The program you see in the
catalog simply changes some pointers to and runs "^" for
you. Don't tell anyone o.k.?
SCRUNCH
-------
Scrunch is a handy machine language program that lets you
store hi-res pictures in a much less than the normal 34
sectors of disk space, thus postponing DISK FULL error
messages. Scrunch is easy to use, especially if you follow
these directions carefully--
TO SCRUNCH (COMPRESS) A PICTURE--
---------------------------------
1. Exit Alpha Plot if necessary. Scrunch has nothing to do
with Alpha Plot.
2. Type "BLOAD SCRUNCH" (return).
3. Load a normal 34 sector hi-res picture onto PAGE ONE by
typing "BLOAD PICTURE, A$2000" (return).
4. Type "CALL 2500" (return). This will put a compressed
version of your picture onto Page Two. It won't be
legible until you unscrunchit (see below).
5. Notice the "BSAVE SCRUNCHPIC, A$4000, L$---" (return).
Use any file name you want and the numbers you see on
the screen.
6. Your picture is now compressed and stored on disk.
Catalog and notice its new size. You may delete the
original 34 sector version of the picture AFTER you are
sure the compressed version will unscrunch.
TO UNSCRUNCH A PICTURE--
------------------------
1. Type "BLOAD SCRUNCH" (return).
2. Load a scrunched picture onto PAGE TWO by typing "BLOAD
SCRUNCHPIC, A$4000" (return)
3. Clear and view Page One by typing "HGR" (return).
This step is optional.
4. Type "CALL 25003" (return).
Scrunch and unscrunch commands may be typed directly from
the keyboard or executed from your Applesoft programs. You
will only need to bload the Scrunch program once (NOT every
time you manipulate a picture). Remember, to use DOS
commands like BLOAD and BSAVE under program control they
must be preceded by a ctrl-D. Consult your DOS Manual.
The Scrunch program is not relocatable. The amount of
scrunching that takes place on a given image depends mostly
on the complexity of that image. Scrunched simple images
occupy the least space.
