Description:
------------
Image production with gdlib has changed between php
php-5.2.5 and php-5.3.3. Run the attached test script on both versions to see the
difference.
Test script:
---------------
<?php
$text = "abcdefghijklmnopqrstuvwxyz\n";
$text.= strtoupper("abcdefghijklmnopqrstuvwxyz")."\n";
$text .= "abcdefghijklmnopqrstuvwxyz\n";
$text.= strtoupper("abcdefghijklmnopqrstuvwxyz")."\n";
$text .= "abcdefghijklmnopqrstuvwxyz\n";
$text.= strtoupper("abcdefghijklmnopqrstuvwxyz")."\n";
$text .= "abcdefghijklmnopqrstuvwxyz\n";
$text.= strtoupper("abcdefghijklmnopqrstuvwxyz")."\n";
$text.= "01234567890123456789\n";
$text.= "!@#$%^&*()_+=-][}{\\|'\";:/?.>,<";
$fontdir = './';
putenv('GDFONTPATH='.$fontdir);
$font = 'verdana.ttf';
$box = imagettfbbox ( 7.5 , 0 , $font , $text );
$width = abs($box[4] - $box[0]);
$height = abs($box[5] - $box[1]);
// Create the image
$im = imagecreatetruecolor($width, $height);
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, $width, $height, $white);
// Add the text
imagettftext($im, 7.5, 0, 1, 10, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
// Set the content-type
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
