GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR PDP.LICENSE, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>

Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General

------------------------------------------------------------------
This external pd library is a framework for image/video processing (and
other raw data packets) that is fast, simple and flexible and as much
as possible compatible with the pd messaging system.
This distro contains the main pdp library and 3 extension libs:
* pdp_scaf (in directory scaf/)
* pdp_opengl (in directory opengl/)
* pdp_guile (in directory guile)
Features:
* packet formats: greyscale and YCrCb encoded images,
binary cellular automata (CA), textures, render buffers,
matrices.
* sources: noise, video4linux and quicktime (with audio), CA, plasma
* sinks: xvideo display, sdl, glx display
* filters: convolution, biquad time, biquad space, CA
* warping: rotate, zoom, stretch
* transforms: colour translation/scaling, grey->palette
* add, mul, mix, random pixel mix
* utility objs: packet register, snapshot, trigger
* packet delay line, loop, ..
* and more.. (see doc/reference.txt)
Optional features
* cellular automata simulator and effects processor with
built in forth extension language (only for mmx)
* opengl 3d processing (gem like, but built around packets)
* embedded guile interpreter
See the README files in the scaf/ opengl/ and guile/ dirs for more
info on the extension libraries.
Requirements:
* pd
* linux
* libgsl
* a video4linux device for video input. special support for
philips webcam included.
* libquicktime (not quicktime4linux!) for quicktime playback.
* libpng for png image loading/saving
* an X display with XVideo extension, glx or SDL for video display.
Documentation:
When you use "make install" to install pd, all docs will be in
the pd doc directory. Right click on an object and select help
for a help patch. The pdp directory in pd's doc contains a
reference.txt file which lists all objects and abstractions and
an introduction and example section.
NOTE: all help patches use a pdp_help_input and pdp_help_output
abstraction. you can edit these to choose which input or output
object you want for the help patches.
Building:
./configure
make
Options for configure:
--enable-mmx compile with mmx support
--enable-pwc force pdp_v4l to use philips web cam
If pd is not installed in /usr/local you'll have to
specify the prefix on the configure command line with
./configure --prefix=/prefix
type
make install
To install pdp in $prefix/lib/pd: the library in externs/
the abstractions in extra/ and the documentation in doc/5.reference
and doc/pdp
You can also try the "buildall" script. This will configure, build
and install the whole distribution. It works for intel/mmx.
NOTE: If you're not using the standard pd install location, and have
everything in a single tree, just untar pdp next to the pd source tree,
or set the prefix dir to the location of the pd source.
Bugs:
See the TODO file. Apart from the few items listed on top of this
file, pdp is fairly stable: i am unaware of crash bugs. If you encounter
a crash please consider sending a bug report.
PiDiP Is Definitely In Pieces
Have a look at Yves Degoyon's PiDiP library, the must have addition
to the basic pdp library. It contains a lot of extra effects (from
EffecTV and FreeJ), a quicktime recording object, streaming modules,
ascii art objects ... (the list is growing rapidly ;)
Yves also did a gem2pd and a pdp2gem object to connect pdp and gem
together.

Acknowledgements
PDP is no longer a one man show. Many thanks to the people who
directly or indirectly contributed to this project. Either by
writing a giant extension lib (thanks Yves) or by contributing code
snippets (Thanks Martin, CK), or by giving mental support, feedback,
bug reports and ideas.
I also wish to thank the GEM crew. This project borrows a lot of ideas
and some code from the GEM project. And while i'm at it, i wish to
thank everyone who contributed code to the PD project as a whole and
the people that are very helpful at answering questions on the mailing
list.
Last but not least i wish to thank Miller for making the PD project
open source. If that didn't happen i wouldn't know what i'd be doing
now :)
Some Remarks:
* New versions of this package can be found at
http://zwizwa.fartit.com/pd/pdp
Experimental relases are in the subdirectory test/
* If you have libquicktime and quicktime4linux installed, this can
give problems with the configure script. Consider removing
quicktime4linux. (libquicktime is a drop-in replacement).
* The modules that depend on system libraries only get compiled when
the configure script can locate them. If compilation or linking fails
please let me know.
* Packets can be processed in a low priority thread with a dropping
mechanism to prevent overload or audio drops, or they can be processed
in the main pd thread. This can be set/unset by sending a "thread x"
message to pdp_control. Processing in pdp thread is off by default.
Use the pd thread for rock solid video timing. Increase the audio
latency to avoid dropouts. If you want low audio latency, and don't
care about a dropped video frame here and there, switch on the pdp
thread. Note that when using the pdp thread, the control flow is no
longer depth first. Additinal delays will be introduced.
* Pdp runs on osx, using an x server (apple or fink) and libquickime
(fink). pdp_xv does not work yet. Once apple includes xv support in
their x server, it should. Until then, use pdp_glx for output.
* Some quicktime remarks: pdp_qt~ is still a bit experimental, you might
try pdp_yqt in yves' lib to see if it works better for you. Also, it
seems that libquicktime does not work with compressed headers. The
suggested codec is jpeg (photo) and uncompressed audio with the same
samplerate as the one pd is using. You can use other codecs, but i've
found this one to perform the best. (hint: compile libquicktime with
mmx jpeg support) Try to avoid the mpga codec. It is haunted.
* The reason i use YV12 and not RGB is simple: it's faster, and for
linear operations it doesn't make much difference. Most camera's and
codecs use a luma/chroma system, and most video cards support hardware
accellerated display. Note that in YUV, the u (Cb) and v (Cr) components
can be negative, so saturation after multiplication with a positive
(or negative) value produces not only black and white, but also red,
green, blue and their complements. In short, in YUV, nonlinear operations
have a different effect than in RGB. Another thing: all the spatial
operations are not implemented "correctly" because of the subsampling
involved.The image packets are 16bit/component planar. This is to
simplify the mmx code and to have a little more headroom and precision
for processing.
* Since version 0.11 there is a type system used for identifying a
packet type and performing type conversion. A type is represented
by a symbol, with subtypes separated by the "/" character. I.e.
"image/grey/320x240" is a grey 16 bit/component image with dimensions
320 by 240. For conversions a wildcard can be specified. I.e.
"image/*/*" which matches image type packets with all encodings
and dimensions.
* Since version 0.12 there are 2 different image data types: "image/*/*"
and "bitmap/*/*". The image type is the native 16 bit/component pdp
type. It supports the subtypes "image/grey/*": one channel grey
scale images, "image/YCrCb/*": luma/chroma packets with subsampled
chroma planes and "image/multi/*": a multi channel planar format (i.e.
to store 3 or 4 channel rgb or rgba data). Almost all processors
use this data type. The bitmap type is an intermediate type which
can contain standard fourcc encoded 8 bit/component images i.e.
"bitmap/rgb/*", "bitmap/yv12/*", "bitmap/grey/*". Currently no processors
support this type natively, so you have to use pdp_convert to convert
them to "image/*/*".
* Writing new objects is not much different than normal pd externs.
Pdp just adds some functions to the pd kernel for package allocation,
manipulation and communication. The api is very raw to keep it as
simple as possible. Since 0.10 there is a pdp_base object you can
derive your objects from. Have a look at pdp_add, pdp_gain and
pdp_noise to see how it works. There is not much documentation, but
i do my best to keep things clean so the code and the header files
should get you started. You can always just send me an email for info,
or ask on the pd-dev list. Since version 0.12 there is a simple forth
scripting language in pdp. This is far from finished, but it should
make pdp programming a lot easier.
* Philips webcam detection is now automatic. However this requires a
fairly recent kernel (one which includes the pwc driver version 8.6
or higher). If you have a pwc and pdp_v4l does not display a
"pwc detected" message, you can conifigure with --enable-pwc. This
forces pdp_v4l to use the pwc api extensions.

--- NEW FILE: TODO ---
todo 0.12.x:
best to do an intermediate release for documentation. 0.13 is not
there yet.
* check reference.txt
known bugs:
* running out of memory (using delay lines or loops) will likely crash pd.
short story: don't, use pdp_control's memlimit for limiting pdp's memory usage.
* no known other fatal (crashing) bugs. please let me know if you find one.
pdp/libpdp remark:
i'm working on a version 2 of pdp. until that is finished, pdp proper will
probably be frozen, except for bug fixes.
todo 0.13:
* yves shm code
* make fobs (all c object code usable in packet forth should be wrapped (automaticly??))
* pdp_xwindow event handling is not thread safe (fixed ?)
* fine tune udp protocol
* solve scheduling probs: pd+3dp = ok, pd+pdp+(3dp) = not
(lots of frags -> video slow, few frags -> audio drops.
pdp threading is not implemented everywhere and is a problem for feedback stuff. think about
a synchronous dropping scheme (central point of failure), like for 3dp. most of the threading
problems could be solved with the new threadsafe pd 0.37 -> check this out)
* add source type to source objects (noise,plasma,constant,...) (solve with forth)
* pdp_crop/pad
* seed plasma
* reorganize headers to cut down compile time (done for core stuff, move pd objects to forth)
* fullscreen x command -> add window manager suppression
* where to solve autoconvert? per type, or central in pdp_base? 2 cases:
- template based autoconvert: in pdp_base
- compatibility based autoconvert: i.e. pdp_add (solve in base: move_passive)
* finish high level packet conversion:
- move 8bit images to packet level (iow: cleanup pdp_qt, pdp_v4l, pdp_xv) (solve with forth)
- add bitmap packet support to source modules (optim for pdp_opengl usage)
(solve with sliceforth: pdp image processing should become independent of image encoding: at least
packed 8/16 rgb(a), and all planar rgb/yuv formats should be well supported: sliceforth feeders)
- get rid of pdp_type* methods
* fix mac/linux name differences (use pdp_video, pdp_movie, pdp_window)
* pdp_xv framerate doc + pwc addons
todo 0.14:
* stress test the memory manager. it looks like there's a bug that pops up after running for a while
* enable audio output on bttv cards in pdp_v4l
* fix cache slicer objects + thread problems (fixed in sliceforth)
* derive as much classes as possible from pdp_base class (obsolete: use forth instead)
* displacement warp, substitution warp, refraction warp, timespace warp, wormhole warp
* check the use of varargs for image processing dispatching routine (obsolete: forth)
* more scopes
* 2D affine transforms parametrized by vectors (center, x-axis, y-axis) (np1 + matrix processing objects)
* some abstractions around pdp_cheby (colour shape, ...)
* efficient rescalers: pdp_double pdp_halve (+ efficient arbitrary scaler in sliceforth)
* move float color conversion and float<->fixed point conv code to system
* crop, shift (pad+scroll)
* solve biquad (blur) mmx boundary init prob (bands at edges: solve with proper init?) (sliceforth)
* optimize blur effect (1 pole ? / dependency stalls) (sliceforth)
* jpeg/png packet and streaming support (pdp_netsend / pdp_netreceive : binary compat issues!!)
* find out why resampling code (warping) is so slow (reg->mem->reg->mem stalls?) (solve in sliceforth)
* mmx profiling (done: sliceforth)
* add audio resampling in pdp_qt~
* use pd_error instead of post for errors
* ascii art packet processors
* 3D time space interpolation
* colour keying
* motion tracking
* moebius transforms
* type multiplexing: find a way to use the same name for packet processors. (solved in forth: polymorhpy)
i.e. pdp_add should add images, but also vectors, ascii packets, textures,...
experimental stuff
* modify 2D rotation to be used as arbitrary rotation (givens)
* add 3D rotation
* frame rate limited delay line (burst delay?)
* optimize resampling code (mipmapped packed 16bit format?)
* better type handling
core is in place. todo:
- better (tree) search algorithm (breadth first + cost)
- add more converters
