 $fillColor = new \ImagickPixel('black');
 $bgColor = new \ImagickPixel('gray');
 $fontSize = 24;
 $text = 'helloworld';
 $text = substr($text, 0, rand(1, 10));
 $font = '/home/koogua/font/yy.ttf';

 $draw->setFont($font);
 $draw->setFontSize($fontSize);
 $draw->setFillColor($fillColor);
 $draw->setStrokeAntialias(true);
 $draw->setTextAntialias(true);
 $draw->setgravity(\Imagick::GRAVITY_CENTER);
 $draw->annotation(0, 0, $text);

 $metrics = $image->queryFontMetrics($draw, $text);

 $image->newImage($metrics['textWidth'] + 30, $metrics['textHeight'] + 10, $bgColor);
 $image->setImageFormat('png');
 $image->drawImage($draw);

 $draw->destroy();

 // $image->writeImage('test.png');

 header('Content-Type: image/png');
 echo $image->getImageBlob();
 exit;

  // $this->response->setContentType( 'image/png');
  // $this->response->setContent($image->getImageBlob());
  // $this->response->send();

enviroment: phalcon

output with font : refresh the page 1- 5 times, capcha image is ok, after 5 times, apache "dead"

output without font : ok

save file : ok

when I set font size to 18, everything is ok, other font size will cause apache "dead", seems 18 is the only luck number, very strange, is it ?

enviroment: another php framework (rewrite is enabled)

output with font : ok

output without font : ok

save file: ok

enviroment: pure php

output with font : ok

output without font : ok

save file: ok

can someone test the above code ?

It seems there something wrong with the font file, change to another common font, everything is ok now.
