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();
}
