PHP Text Image

[prudens]

Hi,

 

 

        I want to use PHP to generate simple anti-aliased texts based on user inputs. Where can I find more information about it?

 

 

Thanks!

And if you can't figure out how to use it I can help you, I'm vary good with GD

Do I need special libraries? I tried:

 

<?php
// Set the content-type
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 = 'Testing...';
// 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);
?>

 

 

And I put "arial.ttf" in my directory... doesn't work!

You usually want to make the header call RIGHT before the imagepng() call. And do you have GD installed?

oh, I ended up having put the font dir like:

 

$font_dir = "/home/etc/etc/website/font.ttf";

Say I want to do something like

 

write.php?text='blahblahblah'

 

How do I make the imagettftext() read the text variable and write?

[DarkWater]

$text = $_GET['text'];

 

O_O

[prudens]

tried it, doesn't work ><

Are you sure you aren't setting $text twice? 

 

You need to comment out your original variable definition. Like this:

 

<?php
//$text = 'Testing...';
$text = $_GET['text'];
?>
