<?php
// Create a blank image and add some text
$im = imagecreatetruecolor(120, 20);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, "A Simple Text String", $text_color);
// Output the image
imagegd($im);
// Free up memory
imagedestroy($im);
?>
Example #2 Saving a GD image
<?php
// Create a blank image and add some text
$im = imagecreatetruecolor(120, 20);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, "A Simple Text String", $text_color);
// Save the gd image
// The file format for GD images is .gd, see http://www.libgd.org/GdFileFormats
imagegd($im, 'simple.gd');
// Free up memory
imagedestroy($im);
?>
Note:
The GD format is commonly used to allow fast loading of parts of images. Note that the GD format is only usable in GD-compatible applications.
