Images in PHP [closed]

Question

Is it possible to create images with PHP (as opposed to simply linking to them via HTML) and if so, where should I go first to learn about such a thing?

Answer 1

I prefer the GD library - check out the Examples, and this example:

<?php
header ("Content-type: image/png");
$im = @imagecreatetruecolor(120, 20)
      or die("Cannot Initialize new GD image stream");
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5,  "A Simple Text String", $text_color);
imagepng($im);
imagedestroy($im);
?>

Outputs:

_{(source: php.net)}

See imagecreatetruecolor.

Answer 2

Yes this is possible. I believe there are multiple libraries to accomplish this. The most widely used is probably ImageMagick which is actually not PHP specific but comes with appropriate bindings.

See also in the PHP documentation.
