Exif to a new created image

[Mitza]

Hey.

 

I made a script to add a border and my name to a image. It looks like this (part of it, excuse me if you find some errors, but it's not the whole script):

 

    header ("Content-type: image/jpeg");
    $add="/.../".$_REQUEST["img"];
    $im=ImageCreateFromJpeg($add);
    $width=ImageSx($im);
    $height=ImageSy($im);

    $border=12; 
    $font_nume = "/.../fonts/2.ttf";
    $text_nume = "Mihai Mustea";
    $font_site = "/.../fonts/4.ttf";
    $text_site = "blog.mitza.org";
    $font_cr = "/.../fonts/3.ttf";
    $text_cr = "©";
    $font_ni = "/.../fonts/3.ttf";
    $img_adj_width=$width+(2*$border);
    $img_adj_height=$height+(2*$border) + 50;
    $newimage=imagecreatetruecolor($img_adj_width,$img_adj_height);

    $border_color = imagecolorallocate($newimage, 0, 0, 0);
    $text_color_cr = imagecolorallocate($newimage, 0, 0, 0);
    $text_color_nume_alb = imagecolorallocate($newimage, 255, 255, 255);
    $text_color_nume_port = imagecolorallocate($newimage, 255, 69, 0);
    $text_color_site_gri = imagecolorallocate($newimage, 90, 90, 90);
    $text_color_linie_1 = imagecolorallocate($newimage, 33, 33, 33);
    $text_color_linie_2 = imagecolorallocate($newimage, 66, 66, 66);
    imagefilledrectangle($newimage,0,0,$img_adj_width,$img_adj_height,$border_color);
    $wn = $img_adj_width / 2 - 65;
    $hn = $img_adj_height - 31;
    $ws = $img_adj_width / 2 - 40;
    $hs = $img_adj_height - 11;
    $wc = $width - 30;
    $hc = 25;
    $image = explode(".", $_REQUEST["img"]);
    $image = str_replace("-", " ", $image[0]);
    $image = strtoupper($image);
    
    $string1 = imagettftext($newimage, "20", "0", $wn+22, $hn, $text_color_nume_alb, $font_nume, "Mihai M.");
    $string3 = imagettftext($newimage, "14", "0", $ws, $hs, $text_color_site_gri, $font_site, "blog.");
    $string4 = imagettftext($newimage, "14", "0", $ws+33, $hs, $text_color_nume_port, $font_site, "mitza");
    $string5 = imagettftext($newimage, "14", "0", $ws+75, $hs, $text_color_site_gri, $font_site, ".org");
    $string5 = imagettftext($newimage, "8", "0", 20, $hs, $text_color_site_gri, $font_ni, $image);

    
    imageCopyResized($newimage,$im,$border,$border,0,0,$width,$height,$width,$height);
    ImageJpeg($newimage, NULL, "100");

 

Basicaly, the script creates a new black background image, adds the text from the footer and after that it adds the original resized image to the black one (eg: http://blog.mitza.org/foto/i/hell-dawn-1.jpg). The "..." is actualy a valid path in the script, I just modified it for this post. As you may already know, PHP-GD (and PHP-EXIF can only read the headers from the image) has no function to write EXIF data to the image. How can I add some EXIF information in the image, without having to create it on the hard disk (save it and than use some classes). Is there any way?

 

Thanks in advance.
