Yes, apache uses only utf-8 as charset and the html content-type meta
tag is set to utf-8 too. Also, the html form validates at
validator.w3.org
plus: first debugging step:
function preview(){
$title = html_entity_decode($_GET['title'], ENT_COMPAT, 'UTF-8');
print_r($title); #verify in view source / web browser that data is
correct before it's sent to imagettftext
I see the characters correctly, and page info in firefox says the
encoding is utf-8.
From the man page:
If a character is used in the string which is not supported by the
font, a hollow rectangle will replace the character
If you are 100% sure that the var $title contains a valid UTF-8
encoded text sting (simply output the string to the browser and set
the page encoding to UTF-8), then the only thing that is left that
might screw up the text-to-image output is the font you are using. As
you might know, you can only use TrueType fonts.
I am quite sure that the font supports the characters. I tried a couple
of fonts that I use in other programs with utf-8. I am, however, not
100% sure that $title is correct utf-8, but I think it is.

I guess I skimmed somewhat too ... but I based my assumption on the
following from the
OPs post:
/index.php/slides/upload:
$title = htmlentities($_POST['title'], ENT_COMPAT, 'UTF-8');
$image =
'/index.php/slides/preview?title='.urlencode($title).'content='.urlencode($_POST['content']);
so the script handle the form submission looks to be generating a url
used as the src of an img.
Yes, the script generates an url to the script that renders the image.
$image is later used in an img-tag. Maybe there is another way to solve
this but this was the only thing I could think of.
I have noted that if I use numerical html entities for åäö (#0197; for
instance) I can see the characters correctly. I guess that would mean
the string passed is *not* correct utf-8.
Here is the current source:
$title = htmlentities( stripslashes($_POST['title']), ENT_NOQUOTES,
utf-8 );
$content = htmlentities( stripslashes($_POST['content']), ENT_NOQUOTES,
utf-8 );
$image =
'/index.php/slides/preview?title='.urlencode($title).'content='.urlencode($content).align=$align;
...
$title = html_entity_decode(get('title'), ENT_NOQUOTES, 'UTF-8');
$im = imagecreatetruecolor(800, 600);
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
//$font = /usr/share/fonts/corefonts/arial.ttf;
$font = /usr/share/fonts/ttf-bitstream-vera/Vera.ttf;
$title_size = 42;
imagefilledrectangle($im, 0, 0, 800, 600, $black);
$this-_string_centered($im, 70, $title_size, $font, $white, $title);
header(Content-Type: image/png);
imagepng($im);
Thus, it leads me back to my previous guess that the font he chose
(georgia.ttf) doesn't have Swedish characters in the set. With that,
I'm not sure, though, because I don't have the Georgia font pack on
here, so it'll have to stay as a guess for now.
Georgia.tff should cover swedish characters - atleast it does on my
system (MPB) ... my little test script in my other post on this thread
works for me ... I have no idea if one should/could expect variations
of supported characters in a TTF font file depending on the system your
on (my guess would be you could rely on all systems that have said TTF
file
to support the same chars - I assume that although it may be compiled
diffferently
for different platforms the source font definition is going to be the
same)
All fonts I have tried works in other applications with utf-8. (I run
lamp on my own workstation at the moment).
If anyone want to see the site or complete source I could send the url
off-list.

[PHP] imagettftext and utf-8 (swedish characters)
Hi, I've ran into some problems when outputing text to an image using
imagettftext. I cannot get swedish characters to work, I just get a
square. I've tried different fonts which I know has those characters
(bitstream vera, arial, times new roman, etc). What am I doing wrong?
I know I must pass utf-8 encoded text and I belive I do but I don't know
how to check it.
HTML form code:
(html document uses utf-8 as charset and apache is set to use utf-8 too)
form action=/index.php/slides/upload method=post
accept-charset=utf-8
input type=text id=title name=title size=70 value= /
/form
/index.php/slides/upload:
$title = htmlentities($_POST['title'], ENT_COMPAT, 'UTF-8');
$image =
'/index.php/slides/preview?title='.urlencode($title).'content='.urlencode($_POST['content']);
/index.php/slides/preview:
function preview(){
$title = html_entity_decode($_GET['title'], ENT_COMPAT, 'UTF-8');
//$title = $_GET['title'];
///@note Hardcoded resolution
$im = imagecreatetruecolor(800, 600);
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
$font = /usr/share/fonts/corefonts/georgia.ttf;
$title_size = 32;
imagefilledrectangle($im, 0, 0, 800, 600, $black);
imagettftext( $im, $title_size, 0, 50, 50, $white, $font, $title );
header(Content-Type: image/png);
imagepng($im);
exit();
}

[PHP] Start/stop daemon using php
Hi, I've written an application in c which I would like to start/stop as a daemon in gnu/linux. The application has the argument --daemon which forks the process and exits the parent. Then it setups a SIGQUIT signal handler to properly cleanup and terminate. It also maintains a lockfile (with the pid) so only one instance is allowed. So, to start this application I created a php site that calls exec(/path/to/binary --daemon /dev/null 2 /dev/null). Everything is working so far, but I cannot get the application to receive the SIGQUIT when I start using php and exec. Not even manually using kill in the shell. It works correctly if I start manually thought. So, is this possible to do? Doesn't exec allow applications with signal handlers? Is there some other way to terminate the application? -- //*David Sveningsson [eXt]* Freelance coder | Game Development Student http://sidvind.com Thou shalt make thy program's purpose and structure clear to thy fellow man by using the One True Brace Style, even if thou likest it not, for thy creativity is better used in solving problems than in creating beautiful new impediments to understanding. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

@4u skrev: Hi, You might consider D-BUS for your application and the D-BUS PHP binding which is available since some days too.

Please have a look at my original release annoucement at the D-BUS mailing list: http://lists.freedesktop.org/archives/dbus/2008-February/009363.html as well as the download URL: https://sourceforge.net/project/showfiles.php?group_id=17176package_id=68954 D-BUS sounds excellent, I will definitely try it out. I have never coded D-BUS myself but I don't think it would be too hard. Even if the application runs on Windows you might be able to use D-BUS for communication.

In an apache process you then do an exec(something). I think apache is probably taking care of the SIGQUIT. Yes, I am using apache (forgot to mention it). Is there a way to stop apache from catching the signals? So, is this possible to do? Doesn't exec allow applications with signal handlers? Is there some other way to terminate the application? Why do you have to kill it with an explicit signal - why not not have a way of communicating with the process that'll make it terminate when you raise a flag or send it a message or something. Currently I have no other way of communicating than a mysql database (it passes data that needs processing) so I thought it would be quick and easy to just raise a signal. I read in another mail about D-BUS which I think would be a better way of communication. /Per Jessen, Zürich -- //*David Sveningsson [eXt]* Freelance coder | Game Development Student http://sidvind.com Thou shalt make thy program's purpose and structure clear to thy fellow man by using the One True Brace Style, even if thou likest it not, for thy creativity is better used in solving problems than in creating beautiful new impediments to understanding. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
