GDF image question

[a2h_]

Code Select Expand

<?php
header("Content-type: image/png");
$im = imagecreatetruecolor(290, 18);
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
imagefilledrectangle($im, 0, 0, 49, 19, $black);
$font = imageloadfont("arcade_n.gdf");
imagestring($im, $font, 10, 5, "ARCADE", $white);
imagepng($im);
?>

Is it possible to:

• Make the background transparent
• Be able to output input text instead of arcade via something like this:
  msg.php?msg=Nice%20day
• Make the image stretch and shrink according to the amount of text

Please give me code as well if you know how to make one of those work. Thanks, because I would love to use this in my SMF Arcade mod!

1. Only think its possible if the image already has transparency..

2. Add this just after the <?PHP

Code Select Expand


$msg = $_GET['msg'];


then change

Code Select Expand


imagestring($im, $font, 10, 5, "ARCADE", $white);


To this:

Code Select Expand


imagestring($im, $font, 10, 5, $msg, $white);


3. I think thats possible but would require a lot of work to find out how many characters the $msg variable is and adjust properly and for the orginal image to be that big..

1. It doesn't use an image, so will I need a template image now?
2. Works, thanks
3. Maybe I'll just have to create a template image for each expected string

You should check out the PHP GD image functions.  Transparency can be set for colors.

Thanks for all the help, I've googled a PHP tutorial for if, and found else and elseif tutorials.
