Simple: Write some text to an image

[aximbigfan]

Hi,

 

I need to create a function to make an image (600X600) and simply write some text in the center (or wherever) of said image. The image must then be returned in the form of a string.

 

I have never worked with images in PHP, or any other editor other than Mspaint. What is the best place to start?

 

Thanks,

Chris

Use the GD library.  There are plenty of tutorials.  Check them out, and also read the manual pages on it.

PHPThumb is a great tool for lots of stuff like this:

Ok, thanks guys!

 

I'll check that stuff out.

 

I figured I'd have to learn GD at some point, so I guess now is the time...

This is what I made. Sure, it isn't the best of the best, but it works perfectly. You need to have the 'arial.ttf' font file in the same dir as the script for this to work.

 

<?php


function texttoimg($input_txt)
{
$handle = imagecreatetruecolor(600, 600);
$white  = imagecolorallocate($handle, 255, 255, 255);
$black  = imagecolorallocate($handle, 0, 0, 0);
imagefilledrectangle($handle, 0, 0, 599, 599, $white);
imagefttext($handle, 20, 0, 300, 300, $black, './arial.ttf', $input_txt);
header('Content-type: image/png');
imagepng($handle);
imagedestroy($handle);
}

texttoimg('Test');


?>
