It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +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 and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, 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 library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete 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 distribute a copy of this License along with the +Library. + + 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 Library or any portion +of it, thus forming a work based on the Library, 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) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +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 Library, 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 Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you 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. + + If distribution of 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 satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be 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. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library 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. + + 9. 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 Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +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 with +this License. + + 11. 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 Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library 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 Library. + +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. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library 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. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser 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 Library +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 Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +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 + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "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 +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. 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 LIBRARY 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 +LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. 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. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It +has been tested both on NVidia-based cards with their binary-only drivers, on +ATI-based cards, and with Matrox-based ones, all of them under XFree 4.x. The +XVideo target features realtime scaling on the windowed output (fullscreen +support will be added on a later stage...), with a lightning fast MMX converter +from RGB to YV12. Make sure to check it out! + +20011103 0.6.1 + +Version 0.6.0 was entirely done during one long coding night, so a few bugs +were present. Anyway, I made the C functions callable by C++ as well (tested +with g++), the example configuration file now has some enabled #defines that +let the example work flawlessly (otherwise it won't run if you haven't got +low-res modes defined in your X configuration. I've got them in, that's why I +didn't notice that...). Then, g++ complained on a few targets for some +duplicated variable definition. That's funny, gcc didn't complain. By the way, +I also tested the whole package with GCC 3.0.1, and it works fine. So, this is +mostly a "cleaned up" version. + +20011102 0.6.0 + +After nine months, I found the time to work again on TinyPTC/X11. Big changes +this time... First of all, now TinyPTC/X11 is released under the LGPL license, +then I (finally) added DGA 2.0 support, although its heuristic stuff for best +videodepth choice isn't tested at all, since my hardware supports 32bpp +natively (if it doesn't work, please tell me, so I can attempt to fix the +problem). Then, I splitted all the various targets in a source/header pair of +their own, in order to improve manteniability and easy new targets addition. +Currently you compile and link all the various targets even if you use only +one of them but don't worry, because with some kind of #define magic and a fair +job done by strip, the executable size won't grow at all. The makefile has been +reworked in order to use automated dependencies and for generate automatically +the NASM includefile for mmx.s from mmx.h. Then, I had to change a variable +name in the supplied example due to clashes with a function with the same name. +Oh, I also added DBE support, if you need it. Of course the documentation has +been updated and the makefile now creates a static library called libtinyptc.a +that can be included in your own programs without having to recompile tinyptc +all the time. Have fun!. + +20010206 0.5.1 + +The makefile now contains a different optimization flag, now the executable is +a bit smaller (at least on my box). I updated the documentation, too (I forgot +to add the __PTC_MEMCPY__ #define). Added a cleanup callback function, in order +to let it be a bit more programmer-friendly. Now you can use PTC_SUCCESS and +PTC_FAILURE in order to check the results of the TinyPTC functions you call. +Documentation now contains NetBSD compilation workaround. + +20001027 0.5 + +The mmx converters were added and the makefile was cleaned up in order to be +a bit more flexible and to support the external assembler code. I left out a +debug fprintf somewhere in the DGA code, now it's just history. The +documentation was updated, too. Nothing more to say, over and out. + +20001306 0.4 + +Bugs are calling... And we're supposed to fix them. There was a glitch in the +32bpp->15bpp conversion code, thanks to tolemaC/Elerium Core for the bug +report. Now the 24bpp conversion modules should work for big-endian machines as +well. Try them if you've got such a system and then tell us. + +20000531 0.3.1 + +Sometimes, fixing a bug, brings another one in. Well, now the only thing that +worked was the 32bpp code. Strange, isn't it ? ;) Anyway, this is fixed now. + +20000527 0.3 + +TinyPTC was developed again after a little pause. Great news this time... I +added color conversion and it seems to work quite well, too. It's rather slow +but I think that some compiler optimizations can speed it up a bit as well. If +it's still too slow for you, feel free to write your own converters and submit +them to Gaffer =) As an added bonus, the 24-32 bpp dilemma seems to be +disappeared... Maybe it's fixed, try and see. Tell me if there's something that +doesn't work. + +20000508 0.2 + +TinyPTC was rewritten from scratch (literally), now the sources are easier to +read and I threw some comment in, too. The XShm support is finished and seems +to work. Tell me if I'm wrong about that. The DGA part wasn't working properly, +it blarfed on the fullscreen-emulation blit code, now it works again. I also +added a 'best-fit' videomode switch logic for fullscreen-emulation code. + +20000505 0.1.1 + +Some kind of preliminary XShm support is now included. There wasn't an UID +check for DGA mode (it needs Root access in order to access video memory +directly). I forgot to include it when I joined the two x11 sourcetrees +together (windowed and DGA). The bitdepth is incorrectly reported as 24 even on +32bpp servers. Strangely enough, my server correctly reports 32bpp. +The pitch value calculation method is wrong. On some cards the assumption +pitch=width*bpp isn't true (TNT cards for example but not Banshees). Damn, I'm +so lame... =) I was calculating it with the logical screenwidth of the +resulting viewport instead of calculating it with the physical screenwidth +returned in the videomode info. The makefile was modified in order to include a +check to "tinyptc.h" during the 'make' operation. + +20000503 0.1 + +Initial release. Supports X11 Windowed and X11 DGA access. No color +conversions, just a bare bones emulation of the windows version. diff --git a/bigscreen/tinyptc/Makefile b/bigscreen/tinyptc/Makefile new file mode 100644 index 0000000..754faf3 --- /dev/null +++ b/bigscreen/tinyptc/Makefile @@ -0,0 +1,90 @@ +# TinyPTC x11 v0.7.3 Makefile +# Copyright (C) 2000-2002 Alessandro Gatti +# +# http://www.sourceforge.net/projects/tinyptc/ +# +# This library is free software; you can redistribute it and/or +# modify it under the terms of the GNU Lesser General Public +# License as published by the Free Software Foundation; either +# version 2 of the License, or (at your option) any later version. +# +# This library is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

TinyPTC is a somehow "low-level" graphics library +that runs on top of XLib, providing only a few functionalities you may +need when working with framebuffer devices. + +* What TinyPTC has to offer + +TinyPTC will simplify your programs that are using X11 to output +graphics. It does all the grunt work for you, so your life will be easier :) + +Actually TinyPTC features: + +- Automatic display management + * XLib, DBE, XVideo, and Mit-Shm window management + * DGA 1.x support, including videomode switch and fullscreen emulation + * DGA 2.x support, including videomode/videodepth switch and fullscreen + emulation. + +- Automatic color conversion + * Detects and converts the internal 32bpp ARGB buffer to 15, 16 and + 24 bpp modes, both RGB and BGR.

It was +programmed by Brian Raiter, and on his site you can find further information +about tricks you can use in order to reduce your programs' size and so on. +Brian Raiter's page is http://www.muppetlabs.com/~breadbox/software/tiny/] + +(*) The color conversion modules were included all at once, you will + get a smaller executable if you include only the ones you need. + +(**) The DGA 1.x executables are so big because the library that manages + DGA+Videomode switch extensions is linked statically. If you look + at the object file you get from x11.c you'll notice the absence + of all those control strings like "Video memory protecting" and + such. I tried to link the library dynamically but the + executables were bigger due to the library loading code being + added. Hopefully with DGA 2.x those two libraries are dynamically linked. + +If you pack them with UPX 1.2 (or better) you'll get a 10%-50% size reduction, +at least on my box... (I'm talking about the supplied example, of course). + +UPX can be found at: http://upx.sf.net +SStrip can be found at: + http://www.muppetlabs.com/~breadbox/software/elfkickers.html + +* TinyPTC's usage + +TinyPTC exports just three functions you can use: + + * int ptc_open(char *title, int width, int height); + * int ptc_update(void *buffer); + * void ptc_close(void); + + (It can't get any simpler, can it?) + + - ptc_open(char *title, int width, int height) + + ptc_open() either opens the window that your application needs for blitting + data on the screen or it will go fullscreen. It accepts a title for the + window that will be created (that title will be discarded for fullscreen + mode) and the window size. For fullscreen mode, TinyPTC will try to find a + suitable videomode first, and it will emulate a fullscreen mode if it didn't + find any (you'll see your application's output in the middle of the screen). + If you enabled best-videomode-choice at compile time, the library will set + the best videmode that fits the supplied window size. It will return + PTC_FAILURE if it fails, otherwise it will return PTC_SUCCESS. + + - ptc_update(void *buffer) + + ptc_update() does a mere blitting of your buffer onto the screen. If + automatic color conversion was enabled it will do the conversion for you. It + will return PTC_SUCCESS if the buffer was blitted and nothing else happened, + else it will return PTC_FAILURE. + + - ptc_close(void) + + ptc_close() closes the window the library created. If it is in fullscreen + mode, it will switch back to normal videomode. ptc_close() is called + automatically when the user presses ESC or closes manually the window. + +Plus, there is an optional callback function that gets called when TinyPTC is +about to shut itself down, called ptc_cleanup_callback, that you must supply if +you are going to use that callback option. Its prototype is: + + * void ptc_cleanup_callback(void); + +* How to compile TinyPTC + +First of all, Laurent Mascherpa (laurent.mascherpa@epita.fr) managed to compile +TinyPTC with the mmx converters under NetBSD. As he told me, NetBSD uses a +slightly different a.out object format, so the files generated by nasm are +useless. Anyway, the workaround consists in modifying the AFLAGS variable in +the makefile: + + From: + + AFLAGS = -f elf + + to: + + AFLAGS = -f aoutb --PREFIX _ + +(Next time I'm going to add some sort of "autoconf"-like scripts ;)) +Please note that you'll also get a static library called libtinyptc.a, ready to +be included in your own programs... + +TinyPTC's behaviour can be set with a few #define lines in the include files. +Here's a list: + + - Callback usage + + __PTC_CLEANUP_CALLBACK__ + + Enables the use of an user-supplied callback function that is called on + application's exit. + + - MMX usage + + __PTC_MMX__ + + Enables the use of MMX code. + + - 32 bpp blit type + + __PTC_MEMCPY__ + + If this is defined, a single memcpy() call will be used to blit the buffer + (Only for 32bpp RGB modes only). + + - Color conversion modules + + __PTC_CONVERTER_32_TO_32_RGB888 + __PTC_CONVERTER_32_TO_32_BGR888 + __PTC_CONVERTER_32_TO_24_RGB888 + __PTC_CONVERTER_32_TO_24_BGR888 + __PTC_CONVERTER_32_TO_16_RGB565 + __PTC_CONVERTER_32_TO_16_BGR565 + __PTC_CONVERTER_32_TO_16_RGB555 + __PTC_CONVERTER_32_TO_16_BGR555 + + __PTC_MMX_CONVERT_32_TO_32_BGR888 + __PTC_MMX_CONVERT_32_TO_32_RGB888 + __PTC_MMX_CONVERT_32_TO_24_BGR888 + __PTC_MMX_CONVERT_32_TO_24_RGB888 + __PTC_MMX_CONVERT_32_TO_16_BGR565 + __PTC_MMX_CONVERT_32_TO_16_RGB565 + __PTC_MMX_CONVERT_32_TO_16_BGR555 + __PTC_MMX_CONVERT_32_TO_16_RGB555 + + Those #define lines, if added, enable the described color conversion module. + Please note that you can't just enable an MMX converter without enabling the + standard converter as well. It doesn't hurt performance or size because the + standard code isn't added if there is an MMX version avaliable. + + - Output targets + + The output target can be chosen by defining one of these #defines in + tinyptc.h: + + __PTC_XLIB__ * This is the raw XLib target. + __PTC_XSHM__ * This is the Mit-Shm target. + __PTC_XDBE__ * This is the X DBE target. + __PTC_XDGA1__ * This is the X DGA 1.x target. + __PTC_XDGA2__ * This is the X DGA 2.x target. + __PTC_XVSHM__ * This is the XVideo+Mit-Shm target. + + - Extra behaviour definitions + + __PTC_ENABLE_CONVERSIONS__ + + If it's enabled, it activates the automatic color conversion. If you will + run an executable that doesn't have the conversions in on a non-32bpp + display, it will silently quit. Ignored for the XVideo+Mit-Shm target. + + __PTC_BEST_VIDEOMODE__ + + Enables the best-fit videomode switching for the requested window size. This + works only for fullscreen executables. + + - Endianness considerations + + __PTC_LITTLE_ENDIAN__ + + Selects the right converter for 24bpp and 32bpp conversion code. Pretty + useless if you don't plan to support those videomodes or little endian + architectures. It has not been tested extensively, so don't assume it's + 100% working. Ignored for the XVideo+Mit-Shm target. + +* DGA considerations + +Although TinyPTC is fairly portable, the DGA mode is a XFree86-only extension +to the X Windowing system. So if you try to compile the fullscreen support on +a non-i386 machine it will complain. Anyway, Mit-Shm and DBE are portable as +far as I know, so is "raw" XLib mode. Please note that you will need either be +root in order to run fullscreen-enabled applications or set the executable as +suid root. + +* XVideo considerations + +The XVideo support has been tested on NVidia (with binary-only drivers), ATI, +and Matrox cards under XFree 4.x. It's totally untested on S3 Savage-based +cards. If you happen to have such a card and want to test it out, tell us! =) + +* Python extension + +Since version 0.7.2, a python extension can be built out of TinyPTC. In order +to get that you've got to use the python target in the makefile and copy the +_TinyPTC.so file whereever is appropriate for your program. The python API +replicates almost entirely the C/C++ one except for pointer management. You +have to use the provided TinyPTC.pixel_array method to allocate the buffers +you'll pass to TinyPTC.ptc_update. The objects returned by TinyPTC.pixel_array +act almost like normal python arrays. In case of doubt, take a look at the +supplied python_test.py file. + +Note that you need SWIG 1.3 or newer to generate the wrapper code. + +* How to contact the authors + +Alessandro Gatti (Rigel) can be reached at a.gatti@tiscali.it +Fred Howell (Fred) can be reached at foohoo@shaw.ca +Glenn Fiedler (Gaffer) can be reached at gaffer@gaffer.org + +Please send all bug-reports, ideas, fixes, additions, and so on.
