#X text 13 348 Objects are like filters \, they change the way messages
flow through them.;
#X text 13 153 You can think of a patch as plumbing. The way water
flows through the plumbing of your house \, messages flow through the
connections in your patch. Objects change the flow of the messages
to allow different things to happen. Messages always go into objects
at the top \, called the inlet \, and always come out at the bottom
\, called the outlet. In PD messages flow from top to bottom.;
#X text 458 236 This is a very simple example of a patch \, the message
"10" can be sent through the "pd this is an object" and can be seen
being passed out the outlet.;

#X text 13 252 You can work with PD in two ways \, the first is in
"edit mode". Edit-mode is where you create your patch by adding objects
and the connections between them. "Run mode" is when you're done with
the construction of your patch \, and you wish to send messages through
it. In run-mode your cursor is an arrow (as it is right now since we
are in run-mode) \, in edit-mode your cursor is a pointing hand.;
#X text 458 136 Messages are what allow objects to communicate with
one and other. Messages can change the way an object acts \, and/or
express the work the object is doing. Messages come in different types.
They can contain words \, numbers and groups of these. The main types
of messages we will be dealing with are floats (numbers). You can click
on a message \, when in run-mode \, to send it through your patch.

#X text 457 67 GUI objects allow you to interact with your PD patch
as it is running. They allow you to change what your patch is doing
without reconnecting the objects. The simplest GUI object is the "Message"
that simply contains a message you want to send in your patch.;
#X text 453 290 A patch that connects a GUI to an object to a second
GUI.;
#X text 531 320 <- This GUI sends a float message (click on it);
#X text 13 66 When working with PD you are dealing primarily with objects
\, GUI (Graphical User Interface) objects \, connections and messages.
These are the building blocks of PD programming. When you connect objects
\, GUI objects \, and messages you are creating a "patch". Patching
is making something complex out of smaller building blocks.;

formats (.jpg \, .png \, .tiff etc.).;

\, try moving the patch if the display seems to be missing.;
#X text 447 -45 To view the image you must initialize the patch. This
is done in "run mode" by clicking on the message box \, and then on
the bang. The image will be displayed in a display window \, off to
the side of the patch.;

#X text 455 -281 Example #5;
#X text 457 -260 We introduce the [#clip] object. It is used with numops
in order to set constraints on the pixel to eliminate color wrapping.
Colour wrapping occurs when the individual pixel values in a grid exceed
255 which results in over-saturation of colour. GridFlow reads colours
as values from 0 (black) to 255 (white). Refer to glossary for more
information on colour.;

#X restore 16 503 pd META;
#X text 12 20 DESCRIPTION: Message \, slider \, toggle \, bang and
number;
#X msg 93 145 hello world;
#X obj 93 168 print;
#X text 181 146 <- Click on this message;
#X text 18 74 Messages control the behavior of objects and it is the
objects that change what a patch does. The first object we're going
to learn is "print". All "print" does is print out the messages you
send it to the terminal:;
#X text 19 197 TIP: If you forget what an object does you can always
double-click (on a mac) or right-click (on a PC) and then choose "help".
;
#X text 19 250 In this tutorial we will use two different types of
objects: "objects" (of which "print" is an example) and GUI objects
\, (of which "message" is an example). GUI objects allow you to interact
with your patch \, control PD and change parameters of objects. We
are going to learn four types of GUI objects (but there are many more):
Slider \, Toggle \, Bang \, and Number.;

10 15 1 10 -262144 -1 -1 0 1;
#X obj 73 393 print;
#X text 21 421 This "hslider" is connected to the print object. This
way we can see what messages the "hslider" sends. Try clicking and
dragging in the Slider. You can change the scale (and other properties)
of some GUI Objects by double-clicking (mac) or right-clicking (pc)
and choosing "properties".;
#X text 13 46 The "message" and "hslider" GUI Objects:;

#X obj 519 210 print Toggle;
#X obj 739 210 print Number;
#X floatatom 739 192 5 0 0 0 - - -;
#X text 466 76 "slider" \, "toggle" and "number" all send messages
made up of floats (numbers). "bang" is a special case and it only sends
the message "bang". Below we're using an argument to the print object
that tags each message sent to the terminal. This way when we have
multiple "print" objects in one patch we can differenciate thier output.
;
#X text 465 268 "toggle" sends the message "1" or "0" \, "bang" always
sends "bang" and if you click and drag on the "number" you can see
it acts a lot like a Slider. With "number" you can also click once
\, and then type a number to send.;
#X text 467 335 TIP: You can send floating point numbers by holding
down the SHIFT key as you click and drag on the "number".;
#X text 467 375 There are other types of GUI objects not covered here.

#X text 12 20 DESCRIPTION: Using PD to create your first patch;
#X text 13 46 Adding Objects:;
#X text 19 75 In order to create a patch you need to first place objects
and GUI objects \, and second make connections between these objects.
To place an object you need to be in "edit-mode". You should now be
in run mode \, so please go to the "Edit" pull-down menu and choose
"Edit mode" at the bottom. You should see your cursor change from an
arrow to a pointing hand.;
#X text 19 175 SHORTCUT: You can press "Control" and "e" simultaneously
in order to toggle (switch) between edit and Run modes.;

#X text 19 355 SHORTCUT: You can press "Control" and "3" simultaneously
in order to place a number. All shortcuts are listed next to the items
in the "Put" menu.;
#X text 453 366 Patch work area:;
#X text 19 215 Once you are in "edit-mode" you are now free to place
objects. To place an object go to the "Put" pull-down menu and choose
"Number". Once you have chosen this menu item you will see that a "number"
gui is attached to your mouse pointer. In order to place the number
into the patch move your pointer to the grey area to the right (in
the "Patch work area" -> Click once to release it from your mouse.
Note that the number is coloured blue. The blue colour shows that an
item in your patch is selected. To unselect any item simply click once
on the blank (white) space between items.;

#X text 453 156 Connecting Objects:;
#X text 19 411 Next we're going to place the familar "print" object
beneath the "number" GUI. Press "Control" and "1" to place an object
box. Again the object gets attached to your mouse and again click once
to place it in the patch area somewhere under the "number".;
#X text 459 41 While the number box is still selected (coloured blue)
you can see a flashing cursor. Type the word "print" into the object
box. The object will retain a dashed line while you type. In order
to create the object you simply need to unselect \, by clicking somewhere
outside the object. Note that once you have clicked to create the object
the dashed line turns solid and an inlet (small rectangle) gets drawn
around the word "print". The objects have now been created!;
#X text 459 185 All connections between objects in PD are created from
outlet to inlet (top to bottom). To start making a connection move
your hand-pointer over the outlet of the "number" gui. When over the
outlet your pointer will change to a circle. When you see the circle
press and hold the mouse button. As you drag (holding the mouse button
down) the pointer you see a line being drawn from the outlet to your
pointer. To attach this connection to another object drag your mouse
to an inlet of another object. The pointer will again change to a circle
and at this point you can release the mouse button. Once released the
objects are now connected! To play with your patch go back into run-mode
and click and drag on the number-box while watching the terminal.;

#X text 12 20 DESCRIPTION: Using Graph on Parent abstractions;
#X text 13 46 What is Graph on Parent?;
#X text 13 76 Graph on Parent is a feature of PD that allows you to
show the GUI objects contained in an abstraction on the parent patch.
This means that you can create abstractions that not only include a
collection of objects but can also include a user interface. To use
graph on parent you simply need to create an abstraction the usual
way but before saving it you need should Control-Click (Right-Click)
on the background (white area) in the abstraction and choose "properties".
>From the properties menu check the "graph on parent" option. Now when
you save the patch and embed it in a second patch all GUI objects will
be visible.;
#X obj 154 250 gop_abstraction;
#X text 13 331 In this simple example there is only one GUI object
\, a slider. Inside the abstraction the slider is connected to an inlet
and an outlet. If you move the slider you can see the result in the
outlet. If you set a value in the inlet with the number GUI you can
see the position of the slider change.;

#X text 13 421 Note you can change the size of the abstractions bounding
box by Control-Click (Right-Click) on the abstraction and choose "properties".
The size of the bounding-box is specified by the "screen width" and
"screen height".;

#X text 29 30 GridFlow is a plug-in for PureData that introduces the
frid (#) data type into the PD environment. GridFlow allows you to
work with live video \, still images and video files in a rel-time
environment.;
#X text 32 97 This section deals with the particular objects related
to GridFlow. GridFlow uses the usual PD "control" objects \, as well
as a set of GridFlow specific objects. Before we get into the tutorials
we will explain the grid "#" \, the most important concept in GridFlow.

;
#X text 10 427 1 - Create a list of numbers using a message box. The
numbers must be seperated by a space. The list can have as many numbers
as you want but only the amount defined by [#import] will be displayed.
As you click on the message box the numbers will appear in the grid.
The numbers are positioned in the grid from left to right and from
the top to the bottom.;
#X text 12 605 3 - Connect the objects to a [display] object or a [print]
object to see the resulting grid. You don't have to "see" the grid
in order to manipulate it.;

#X text 8 267 The following examples illustrate how grids are interpreted
and represented in GridFlow.;
#X text 3 402 Steps for creating a grid:;
#X text 11 537 2 - Create the [#import] object and indicate the parameters
you want as grid dimensions. By indicating 3 3 in brackets following
[#import] \, you are creating a grid that has 3 rows and 3 columns.
This 3 by 3 grid will display 9 numbers.;
#X text 518 516 works like the [#import] object but allows you to put
your grid parameters and values into one message box;
#X text 10 29 A grid is composed of rows and columns that contain numeric
data. For instance \, a checkerboard is a grid that consists in a series
of rows and columns containing information: a dark square or a light
square.;
#X text 10 91 Computers interpret images as three-dimentional grids:
the rows (height) and columns (width) contain pixel positions. There
are usually three channels (depth) of rows and columns. Channels are
the colours that make up an image. Each channel is a single colour
\, usually red \, green and blue (RGB). Videos are also interpreted
as grids since they are a series of still images.;
#X text 9 194 Because GridFlow uses grids \, images and videos are
represented as such. GridFlow objects that accept or produce grids
are identified by the number sign "#" (think of that symbol as a mini
grid). From now on we will refer to images and videos as grids.;

#X text 12 20 DESCRIPTION: Learning "metro" \, "counter" & "random"
;
#X text 13 96 Using the "metro" object:;
#X text 21 47 In this section we will learn three new objects \, "metro"
\, "counter" \, and "random". Metro sends a bang at regular intervals
\, just like a metronome.;

#X text 21 187 You can turn a Metro on and off by sending it a "1"
or "0" message. Because a toggle sends 0/1 messages \, we can simply
connect it directly. Metro also accepts an argument (words or numbers
wirtten after the object name). This argument is how fast the metro
should send out bangs (in milliseconds). You can always change the
speed of the metro by sending it number messages through the rightmost
inlet.;

You can also change the upper limit by sending a message to the rightmost

#X text 461 77 "counter" is simply an object that counts. It can count
up \, count down and count up and then down. Where it starts and where
it stops are all definable. This is the counter that in included with
Gem \, it is not compatible with other counter objects.;
#X text 461 274 The first argument for counter is the lower limit (number
to start counting at). The second is the upper limit to count to. The
third argument is the direction in which to count. "1" means forward
\, "2" means backward and "3" means forward and then backward. You
can also use the three rightmost inlets to change the behaviour of
counter. The rightmost inlet is the upper limit \, the second right-most
the lower limit \, and the third right-most as the direction. The rightmost
outlet sends out a bang message when the counter loops.;
#X text 681 193 Rightmost inlet;
#X text 651 173 Second Rightmost inlet;
#X text 621 153 Third Rightmost inlet;

#X text 29 -633 Example #4 the [#clip] object is used with numops in
order to set constraints on pixels to eliminate color wrapping. Colour
wrapping occurs when the individual pixel values in a grid exceed 255
which results in of colour. GridFlow reads colours as values from 0
(black) to 255 (white). Refer to glossary for more information on colour.

#X text 12 20 DESCRIPTION: nested patches using abstractions & subpatches
;
#X text 13 46 What is an abstraction?;
#X text 23 76 Since objects are very simple in Pure-Data doing complex
tasks often leads to very complex patches. Often it is useful to use
the same bit of patching you do for one project for another. Pure-Data
has a facility to "nest" \, that is to take a number of objects in
a collection and place them into a group that looks like a single object.
This is also handy to make a complex patch look simple and clear by
hiding the nitty-gritty details. There are two types of these collections
\, the subpatch and the abstraction.;

#X text 13 216 The subpatch;
#X text 23 246 Subpatches are collections of objects that get "hidden"
inside a container that looks like a normal PD object. Subpatches are
created by creating an object box \, and typing the word "pd" followed
by whatever you want to describe the contents of the subpatch. Subpatches
are saved at the same time as the "parent" patch. Here is a subpatch:
;
#N canvas 0 22 460 310 subpatch 0;
#X obj 30 34 inlet;
#X obj 30 77 outlet;
#X text 99 35 This is inside the subpatch.;

#X restore 178 359 pd subpatch;
#X floatatom 178 336 5 0 0 0 - - -;
#X floatatom 178 387 5 0 0 0 - - -;
#X text 23 416 To open a subpatch simply click once on the subpatch
in run-mode or control-click (or right-click) and select open in edit-mode.
Both subpatches and abstractions communicate with the parent patch
through special objects called "inlet" and "outlet" for each "inlet"
in a subpatch or abstraction an inlet is created on the subpatch. This
example has one inlet and one outlet.;

#X text 453 46 The abstraction;
#X text 463 76 Abstractions are very similar to subpatches. They are
collections of objects that are "hidden" inside PD objects \, and they
both use "inlet" and "outlet" objects to communicate with the parent
patch. The difference between subpatches and abstractions is that abstractions
are saved in a separate file from the parent. This means when you save
the parent patch containing abstractions the abstractions are not saved.
The abstractions are saved as separate files so that they can be used
in multiple patches. A second feature that exists in abstractions and
not in subpatches is the ability to use arguments. "send" and "receive"
can be used inside abstractions to send data without connections (patch-cords).

#X obj 682 277 print;
#X obj 564 253 abstraction 1 2;
#X text 463 316 To create an abstraction all you need to do is create
a new PD patch ("File" -> "New"). Create the contents of the abstraction
and then save it in the same directory as the patch you want to use
it in. In this case the abstraction is saved as "abstraction.pd". Once
saved you can easily embed the abstraction simply by typing its name
\, without the .pd extension \, into an object box.;

#X text 453 416 Dollarsign in object boxes;
#X text 463 446 If you open the above example you will see that the
familiar "pack" object has a number of "$" arguments. The "$" arguments
in a object box differ entirely from the "$" used in message objects.
When you use a "$" in an object box inside an abstraction the values
get replaced with the arguments to that abstraction. In the case above
the "pack" object's first argument "$1" gets replaced with the first
argument of the abstraction "1" "$2" gets replaced with the second
argument "2".;

#X text 12 20 DESCRIPTION: Using pack \, unpack and route with lists
;
#X text 19 75 In the Pure-Data introduction we discussed the three
different types of data in PD. These are floats (numbers) \, symbols
(words) and lists (groups of floats and words). Floats and symbols
are known as atoms. Atoms are single elements \, they do not contain
spaces or other special characters. Atoms can be grouped into lists.

#X text 13 46 What is a list?;
#X msg 145 216 list one two three;
#X obj 145 239 print this is a list;
#X text 19 155 Lists can be created in a number of ways \, but we are
going to cover the two most common ways of creating lists. The most
simple way to create a list is to type the list into a message box
starting with the word (symbol) "list":;
#X text 19 295 The "pack" object is the second most common way to create
a list. "pack" allows you to take individual atoms and combine them
into a single list. "pack" accepts a number of arguments. Each argument
defines the type of atom in the resulting list. The "f" argument creates
an inlet that accepts float atoms. The "s" argument creates an inlet
accepts symbol atoms. The number of arguments is the same as the number
of elements in the resultant list.;
#X text 19 405 "pack" is the first object we are going to learn that
has a "cold" inlet. Some control objects in PD have "hot" and "cold"
inlets. When you send a message to a "cold" inlet the object does not
generate any output (it does not send any messages). When "hot" inlets
get messages then the object does generate output. The leftmost inlet
is always the "hot" inlet and all other inlets are "cold" or in some
cases all inlets are "hot";
#X text 75 521 sets the first atom "1" and then sends the list;
#X text 132 543 sets the second atom "2";
#X obj 45 566 pack f f;
#X text 459 45 Note that if you do not set the second and onwards atoms
via thier "cold" inlets and you generate the list by setting the first
atom via the "hot" inlet then all float atoms will be set to "0" and
all symbol atoms will be set to "symbol" in the resultant list.;

#X text 718 261 Third Atom;
#X text 459 156 The "unpack" object is very similar to the "pack" object
except it works in reverse. "unpack" takes a list and splits it up
into a number of atoms. It uses the same arguments as "pack" but generates
outlets rather than inlets.;

#X text 453 319 "route" object;
#X text 459 349 The "route" object sorts lists based on the first atom
of the list. It as a number of float or symbol arguments. For each
argument "route" creates one outlet. "route" also creates one additional
rightmost outlet for rejections. For each list route gets it compares
the first atom to all its arguments. If the first atom matches one
of the arguments it the rest of the list \, without the first atom
\, gets send through the outlet corresponding to that argument. If
the first atom of the list does not match any arguments the entire
list \, including the first atom \, gets sent out the rejection outlet.

#X text 12 20 DESCRIPTION: Advanced uses for the message object;
#X text 19 45 In Pure-Data there are two distinct concepts with the
name "message". Messages are the data that gets send in PD from object
to object. There is also the Messsage object that contains a message
you want to send. The message object is the first GUI object we covered
in this tutorial. The message is not the only way to send messages
in a patch \, since all GUI objects also send messages. So what makes
the message object different? The message object can sent messages
of any type \, where a number for example can only send float (number)
messages. There are a number of powerful features in the message object.
We are familar with the "usual" way of using the message object:;
#X msg 163 208 hello;
#X msg 212 208 bye;
#X obj 196 238 print messages;
#X text 459 556 Note: It is a very common mistake to confuse the message
object with an object box. The object box is framed in a rectangle.
The message object has a notch removed from the right edge.;
#X obj 106 385 print messages;
#X msg 106 358 hello \, bye;
#X text 19 305 You can send multiple messages in succession from a
single message box by using a comma " \, " between the messages. The
messages get send from left to right.;

#X text 13 416 Semicolon in message boxes;
#X text 13 276 Comma in message boxes;
#X text 19 445 Just like you can specify receive tags directly in GUI
objects you can also use a message box to send a message directly to
a particular "receive".;

#X text 453 46 Dollarsign in message boxes;
#X msg 534 175 \$1 \$1 \$1;
#X msg 534 154 10;
#X text 459 75 In messages there are placeholders that start with "$".
These placeholders are variables that get replaced with messages you
send to the message box. In the example below we have a single message
"10". Each "$1" in the message box gets replaced with the message "10".
;
#X text 601 175 \$1 placeholder gets replaced;
#X text 570 154 message sent to message box;
#X msg 534 304 list 1 2;
#X text 600 304 a list with items "1" and "2";
#X msg 534 325 \$2 \$1;
#X text 584 325 \$1 becomes "1" and \$2 becomes "2";
#X obj 534 347 print reverse-list;
#X text 459 235 The "$1" placeholder refers to the first element of
the list the message box gets from its inlet. We can use this to use
a message box to reverse the order of elements (called atoms) in a
list.;
#X text 459 385 In this case the list "1 2" has two elements (called
atoms) when this list gets sent to the inlet of a message box its atoms
are available to the message box through the $ variables. \$1 gets
replaced with the first element \, \$2 the second and so on.;
#X obj 534 197 print repeated-message;
#X obj 480 511 print complex-message;
#X msg 480 468 list Fred Marcus;
#X text 607 468 a list with two symbol atoms;
#X msg 480 489 Hi \$1. \, Ya know \$2?;
#X text 623 489 Becomes: "Hi Fred \, Ya know Marcus?";

as a set of GridFlow specific objects. Before we get into the tutorials
we will explain the grid "#" \, the most important concept in GridFlow.

#X text -16 -67 Convolve is an abstraction used for modifying an image.
In this patch you can choose to create a "blur" \, to view "edge detection"
\, to add a "laplacian mask" or to "sharpen" an image. The image must
be loaded \, the transformation selected and the metro started before
seeing the transformation applied to the image.;

#X text 19 575 For more info see: send-help.pd \, receive-help.pd \,
netsend-help.pd and netreceive-help.pd;
#X text 459 75 While "send" and "receive" allow you to send messages
without connecting objects with patch-cords "netsend" and "netreceive"
do the same but communicate between objects using TCP/IP the internet
protocol. This means that you can send messages from a patch running
on one machine to a second patch running on a second machine on the
same network \, or even over the internet.;
#X text 19 545 You can also send messages using UDP rather than TCP/IP.
See "more info" below for details.;
#X obj 589 292 netreceive 8001;
#X text 459 185 The first argument of "netreceive" is the port the
netrecive should listen on. "netsend" can connect to this port from
other machines. "netreceive" has two outlets. The first outlet sends
out the messages it receives over network \, and the second argument
send a "1" when netsend is connected and "0" when netsend disconnects.

#X obj 503 563 netsend;
#X text 459 355 "netsend" is controlled using three messages: "connect"
\, "disconnect" and "send". "connect" has two arguments \, the host
or IP and the port number you wish to connect to. There needs to be
a "netreceive" listening on the port you connect to. "disconnect" drops
the current connection. "send" sends any arguments to the "netreceive"
over the network. The single outlet of "netsend" prints "1" when a
connection is made and "0" when the connection is lost.;

#X text 733 536 Send message;
#X text 19 75 In some cases you will want to send messages without
connecting objects. You may be sending one message to many different
places that would make connections too laborious. "send" and "receive"
both have a single argument. This argument is the tag name for the
communication. "send" will always send any messages it gets in it inlet
to any number of "receive" objects in a patch with the same tag name.
"s" and "r" can be used in the place of "send" and "receive".;
