[SOLVED] php text to png

[jarvis]

Hi all,

I've found this brill script which can produce a graphic of your text with a given font:

<?php

header("Content-type: image/png"); //Picture Format
header("Expires: Mon, 01 Jul 2003 00:00:00 GMT"); // Past date
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // Consitnuously modified
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Pragma: no-cache"); // NO CACHE

/*image generation code*/
//create Image of size 350px x 75px
$bg = imagecreatetruecolor(350, 75);

//This will make it transparent
imagesavealpha($bg, true);

$trans_colour = imagecolorallocatealpha($bg, 0, 0, 0, 127);
imagefill($bg, 0, 0, $trans_colour);

//Text to be written
$helloworld = isset($_GET['text']) ? $_GET['text'] : "hello World";

// White text
$white = imagecolorallocate($bg, 255, 255, 255);
// Grey Text
$grey = imagecolorallocate($bg, 128, 128, 128);
// Black Text
$black = imagecolorallocate($bg, 0,0,0);

#$font = 'arial.ttf'; //path to font you want to use
$fontsize = 20; //size of font

//Writes text to the image using fonts using FreeType 2
imagettftext($bg, $fontsize, 0, 20, 20, $grey, $font, $helloworld);

//Create image
imagepng($bg);

//destroy image
ImageDestroy($bg);
?>

Simple question, how would you use the above for mutliple graphics and how do you use it on a page? I've tried adding other information around it and it simply errors or won't show anything else!

Am new to this side of things so please note this is not me being ignorant, just trying to learn & work it out!

 

Thanks

if that code is saved in a file called image.php then you'd this in your page where you want the generated image to be displayed to.

<img src="image.php?text=your text here" />

Oh jesus, it was that simple!? :-(

 

So in order to maximise it's benefits, would I add a folder called font, add my particular font to that dir and then reference it in the code?

Or does the font still need to be installed in the server font dir?

 

Thanks again!

Yes. For more info read the manual on the imagettftext function. You should also read the manual on GD
