PHP text to image

Question

I got good result in PHP/GD to write text to image template, text wraps fine but is not "smooth", here is the code I am using:

<?php

header("Content-type: image/png");

$text = "go to school go to school go to school go to school go to school go to school go to school go to school go to school go to school go to school ";
$arrText=explode("\n",wordwrap($text,60,"\n"));

$im = imagecreatefrompng("template.png");
$y = 15; //vertical position of text
foreach($arrText as $arr)
{
    $white = imagecolorallocate($im,0,0,0); //sets text color
    imagestring($im,5,15,$y,trim($arr),$white); //create the text string for image,added     trim() to remove unwanted chars
    $y = $y+20;

}
imagepng($im);
imagedestroy($im);
?>

Define smooth. When "wordwrap" is called it makes a hard break at 60, or `n`, characters. — Robert K, Aug 07 '12 at 17:32
What is the question? Are you asking how to make the text "smooth"? — davidethell, Aug 07 '12 at 17:32
@BasheerHallak I believe you can post a link, but I think we all understand now that it's antialiasing that you want. Please add that to the question. — FThompson, Aug 07 '12 at 17:58

Please try this:-

Remember : set correct path for font $font = 'arial.ttf';

    header('Content-type: image/png');

    // Create the image
    $im = imagecreatetruecolor(400, 30);

    // Create some colors
    $white = imagecolorallocate($im, 255, 255, 255);
    $grey = imagecolorallocate($im, 128, 128, 128);
    $black = imagecolorallocate($im, 0, 0, 0);
    imagefilledrectangle($im, 0, 0, 399, 29, $white);

    // The text to draw
    $text = 'go to school go to school go to school go to school go to school go to school go to school go to school go to school go to school go to school';

   // Replace path by your own font path
    $font = 'arial.ttf';

    // Add some shadow to the text
    imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);

    // Add the text
    imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

    // Using imagepng() results in clearer text compared with imagejpeg()
    imagepng($im);
    imagedestroy($im);

Try turning on anti-aliasing:

imageantialias($im, true);

Does that make it look any better?

Or else try imagettftext with a truetype font:

imagettftext ( $im, 15, 0, 15, $y, $white, 'fontfile.ttf', trim($arr));
