Hi Bill,

Thank you for the reply. I 'm applying for svg support in tuxmath and tuxtype. I came to know there is some support for svg in tuxpaint, that's why I asked about it in the list. So you say it's very hard to port the code in tuxpaint to tuxmath and tuxtype?

Thanks

Bristow.

hello all,          I am akash gangil , an undergraduate student , from
India ,New Delhi.
I wish to work for Tux4Kids this summer'09.
Nobody replied to the last mail that i posted to
tuxmath-devel@lists.sourceforge.net .         So i am mailing to this list.
( Expecting a positive reply , i am unable to submit any patch currently due
to my exams , but am working on some of the FIXME's in the
        code and wish to contribute soon .. so plz. dnt ignore my mail.)

I am concentrating on just Tux4Kids this GS0C , as it's surprisingly fits in
my skill set and interests.
Moreover , I am consistently plannning how to implement the ideas.
The following three ideas really excite me in the Tux4kids list of proposed
ideas for GSoC'09.
http://socghop.appspot.com/document/show/user/david_bruce/tux4kids*1. To
achieve the first task that is Speech output of the word or phrase to be
typed on the tux typing ideas list , i researched a bit and came to the
following things,* Rather than using sound files, which would not only
increase the size of the application but would also be cumbersome. I went
through two tts libraries namely eSpeak and Festival , but found Festival to
score over eSpeak in it's diction , it's very much as if someone is talking
to you.
 Using ?Festival?, a text to speech , open-source, cross-platform library
written in C++ can be very handy. Festival can easily be integrated into
current code . Moreover , the most important , ?DICTION? , is the ultimate
stronghold of Festival , which is the best available. I have gone through
it, and have a good idea of how to apply it to get my work done.
http://en.wikipedia.org/wiki/Festival_Speech_Synthesis_System
http://www.cstr.ed.ac.uk/projects/festival/ Overview: the spech output of
the word or text typed is redirected to a file , Ex: it can be used to speak
the data of the file as follows:

int main(int argc, char **argv)
{
   EST_Wave wave;
   int heap_size = 210000;  // default scheme heap size
   int load_init_files = 1; // we want the festival init files loaded

   festival_initialize(load_init_files,heap_size);

   // Say simple file
   festival_say_file("/etc/motd");

   festival_eval_command("(voice_ked_diphone)");
   // Say some text;
   festival_say_text("hello world");

   // Convert to a waveform
   festival_text_to_wave("hello world",wave);
   wave.save("/tmp/wave.wav","riff");

   // festival_say_file puts the system in async mode so we better
   // wait for the spooler to reach the last waveform before exiting
   // This isn't necessary if only festival_say_text is being used (and
   // your own wave playing stuff)
   festival_wait_for_spooler();

   return 0;
}

 Not only this , using Festival would also help when Tux Typing is modified
to (LAN Game,if done so), as Festival also has a server/client API ( so it
can be run on a single computer while it can fork it's child for the
clients).Easy implentation , portability and it's cross-platform aspects
make it the best option avilable.*2.  Support for LAN multiplayer mode.
This is probably the most ambitious, as it will require restructuring the
game into client and server programs.                  Networking to be
accomplished   using SDL_net.
*
   I am interested in it because one of my ongoing projects is very similar
to this .
   I am working on file broadcasting using BSD sockets via (UDP protocols)
, ( using threads with TCP protocol)..
   work on this is on , and continuous progress is being made .
   I am attaching the src code of the files which transfer media files b/w
two computers on a linux system.

   The code for broadcasting (using threads via TCP protocol) is almost
complete but still requires some fixes.

   I know the GSoC proposal is bigger than this and it uses SDL_net library
.
*        *   plz , let me know your opinions on this..

   But there are various analogies in the UNIX SOCKETS functionality and
SDL_net which helps me to easily carry out this task..


*3. Tux Typing could also benefit from a configuration program to support
editing of word lists, phrase lists, and setting of options.
*
   I am quite comfortable with Qt4  and Qt4 Designer and have developed
minor apps. using Qt4 Designer as well as have hardcoded them.
   Currently I am working on the proposed model of this configuration
program to be implemented using Qt.
   I would be pleased to work on this two.


I would really like to know the views of you people whether good or bad on
primarily these three ...
what's ur take on this,

regards
akash gangil

Hi all,

I'm Bristow, pre final year B-tech student from India. I would like to
contribute to the tux4kids community. I need to know whether svg support is
added to tuxpaint. Looking forward for your replies.

thanks

Bristow

I'd actually be interested in seeing Festival used in Tux Paint,
especially if it does a good job at reading translated words
(i.e., if it can TTS more than just english).  Since we have such
a numerous collection of stamps, and don't always have translated
descriptive audio sounds for them, it'd be nice to have something to
fall back to, other than silence.

(Also, although recordings of humans are often more pleasant to listen to,
if the descriptive string changes, the audio file is no longer the same.
I think that's already the case for a number of sounds that we pulled
from ChildsPlay... they describe the animal, but they don't say _exactly_
the same thing as the text on the screen.)

I also wonder, how hard is it for Festival to report which part of the
string is currently being spoken, so we can highlight it as the speech
is played back?  (Helpful in teaching kids to read.)

Thanks,

-bill!

Tux Paint already supports SVG.  It is currently only used for Stamp
artwork, but once the UI system is updated to allow for differently-sized
elements (buttons, dialog boxes, etc.), SVG will become useful for UI artwork
as well.  But it should be trivial to utilize what we have for that.
(In fact, we should do that soon, anyway, to support SVGs in the UI,
even if they can't scale abitrarily, yet.)

BTW - Whenever anyone brings up the topic of SVG support in TuxMath and
TuxType as a GSOC project (I guess it's in this year's "ideas" list again),
I make a point to mention that Tux Paint already has some code, which
shouldn't be _terribly_ difficult to port over to the other two apps.

Just sayin'...

What kind of experience do you have with accessibility software?
(i.e., have you played with such tools under Linux, Windows and/or Mac)

One major place where Tux Paint could benefit is an on-screen keyboard
that can be used to enter text using the Text (and, eventually, Label) tools.

Another topic that I just mentioned in a reply to another GSOC student
applicant is the fact that Tux Paint's UI is 'stuck' at its current size.
This can make it difficult to use on high resolution screens (esp. when the
DPI is very high, causing the buttons to be very small, physically -- the
OLPC XO-1 laptop is a good example... it's a very small, very high-res
display, so the buttons in Tux Paint look very small compared to, say,
my Dell laptop).

The UI element sizes, and all calculations regarding when they're being
clicked/etc. is all hard-coded.  It'll be a tremendous amount of work,
and you'll have to be very careful, to make it dynamically-sized.

Adding UI theme support would also be beneficial.  (The ability to switch
from the current 'candy'-like theme to something much simpler and
higher-contrast, for users with vision impairments.)

UI theming will also help the adult users who wish to use Tux Paint for
serious matters.  (The question has come up numerous times!)

And, of course, once the features are coded, the options will need to be:
* Made available via command-line
* Made available via configuration file
* Config. file options exposed in "Tux Paint Config" GUI tool
* Documented

Hope that helps,

-bill!
