Hi, I'm using this script to simply create an image from text. What I would like to know is how to save the image instead of printing straight to browser;
// an email address in a string
$string = $post[$key];
// some variables to set
$font = 4;
$width = ImageFontWidth($font) * strlen($string);
$height = ImageFontHeight($font);
// lets begin by creating an image
$im = @imagecreatetruecolor ($width,$height);
//white background
$background_color = imagecolorallocate ($im, 255, 255, 255);
//black text
$text_color = imagecolorallocate ($im, 0, 0, 0);
// put it all together
$image = imagestring ($im, $font, 0, 0, $string, $text_color);
I know its probably just one line of code at the end but im not sure which GD function to use.
Any help would be much appreciated, Regards, Phil.
EDIT:
I have tried the following but just get a balnk black box;
// an email address in a string
$string = $post[$key];
// some variables to set
$font = 4;
$width = ImageFontWidth($font) * strlen($string);
$height = ImageFontHeight($font);
// lets begin by creating an image
$im = @imagecreatetruecolor ($width,$height);
//white background
$background_color = imagecolorallocate ($im, 255, 255, 255);
//black text
$text_color = imagecolorallocate ($im, 0, 0, 0);
// put it all together
imagestring ($im, $font, 0, 0, $string, $text_color);
imagepng($im, 'somefile.png');
imagedestroy($im);
