Re: [Tuxpaint-dev] Multilingual support in stamps

It seems that if the locale is not present in the operative system, the function(s) getenv() or g_win32_getlocale() returns the default C locale. This was stuck in the mailing list queue, sorry. (It's chock full of spam in there, so I'm trying to clean out the non-spam stuff and then go and discard the rest.) I'll look at this patch tonight, and add it to CVS.

[Tuxpaint-dev] libSDL_ttf is bug-infested
Version 2.0.7 came out Oct 30. Debian-unstable still only has version 2.0.6. Among the many terrible bugs that were fixed: 2.0.7 * Fixed memory corruption problems with some italic fonts * Fixed crash when opening a font file that doesn't exist 2.0.6 * Fixed memory corruption problem with small point sizes Yow! Should all italic fonts be blocked? Also, the library provides no access to the character map. The only way to tell if a character is junk is to compare it it pixel-by-pixel against one that surely is junk. Also, the library appears to randomly return NULL when rendering something. This is horribly painful. Currently, the Tux Paint code relys on a font to work if it worked before. All fonts are tested at startup; if they work at that time then they ought to continue working. BTW, I did fix two other problems. Things may work better. ___ Tuxpaint-dev mailing list Tuxpaint-dev@tux4kids.net http://tux4kids.net/mailman/listinfo/tuxpaint-dev
[Tuxpaint-dev] bug right here
This'll crash Tux Paint:
error = Find_Glyph(font, c, CACHED_METRICS|CACHED_PIXMAP);
if( error ) {
SDL_FreeSurface( textbuf );
return NULL;
}
With some fonts, you'll get a box. With others, not. While all
fonts should provide such a box, the library can surely draw
one if the font doesn't provide it.

BTW, it looks like Tux Paint is reloading the font and/or re-rendering the text when the selector is scrolled. I'll see if I can stop that, as it just slows things down. No. Be careful! It'll reload whenever it needs a font it hasn't used before. So it'll be slow scrolling down, and then fast scrolling up. It'll stay fast until you touch the text controls. The reload is required AFAIK, since the SDL_ttf library won't allow a size change without reloading. The alternative is insane I think. The number of fonts that would need to be kept open would be: families * 4 * number_of_sizes ___ Tuxpaint-dev mailing list Tuxpaint-dev@tux4kids.net http://tux4kids.net/mailman/listinfo/tuxpaint-dev
Re: [Tuxpaint-dev] Segfault at startup
I found a second font that'll cause the crash, out of 116 families I tried. Here they both are: http://luneelfique.free.fr/elvishring.otf http://www.webpagepublicity.com/free-fonts/v/Varicelle.ttf Same procedure: set bold (maybe not needed) set italic set the largest font size use pH (no quotes) as text Supposedly the very latest library will survive this, but that version hasn't even made it into Debian-unstable yet. BTW, I'm linking with the Electric Fence library. This puts a guard page after every memory allocation. Use -lefence to link it in. ___ Tuxpaint-dev mailing list Tuxpaint-dev@tux4kids.net http://tux4kids.net/mailman/listinfo/tuxpaint-dev
[Tuxpaint-dev] Paths for fonts on Win32, Mac OS X BeOS?
In setup(), we have the following that Albert C. recently added:
if (!no_system_fonts)
{
#ifdef WIN32
// add Windows font dir here
#else
loadfonts(/usr/share/feh/fonts, 0);
loadfonts(/usr/share/fonts, 0);
loadfonts(/usr/X11R6/lib/X11/fonts, 0);
loadfonts(/usr/share/texmf/fonts, 0);
loadfonts(/usr/share/grace/fonts/type1, 0);
loadfonts(/usr/share/hatman/fonts, 0);
loadfonts(/usr/share/icewm/themes/jim-mac, 0);
loadfonts(/usr/share/vlc/skins2/fonts, 0);
loadfonts(/usr/share/xplanet/fonts, 0);
#endif
}
Can Win32, Mac OS X and BeOS folks let me know what paths would be good
to add for your respective OSes?
Thanks!
