Draw with form data

 
<?php
    $_GET["size"] = 44;
    $_GET["text"] = "Hello, world!";
    $size = imagettfbbox($_GET["size"], 0, "ARIAL", $_GET["text"]);
    $xsize = abs($size[0]) + abs($size[2]);
    $ysize = abs($size[5]) + abs($size[1]);
    $image = imagecreate($xsize, $ysize);
    $blue = imagecolorallocate($image, 0, 0, 255);
    $white = ImageColorAllocate($image, 255,255,255);
    imagettftext($image, $_GET["size"], 0, abs($size[0]), abs($size[5]), $white,"ARIAL", $_GET["text"]);
    header("content-type: image/png");
    imagepng($image);
    imagedestroy($image);
?>

Outputting Text

 
<?php
    $image = imagecreate(400,300);
    $blue = imagecolorallocate($image, 0, 0, 255);
    $white = ImageColorAllocate($image, 255,255,255);
    $_GET["size"] = 44;
    $_GET["text"] = "Hello, world!";
    imagettftext($image, $_GET["size"], 15, 50, 200, $white,
            "ARIAL", $_GET["text"]);
    header("content-type: image/png");
    imagepng($image);
    imagedestroy($image);
?>

Using the imagettftext() Function

 
<?php
    define("WIDTH", 300);
    define("HEIGHT", 100);
    define("F_SIZE", 40);
    define("F_ANGLE", 0);
    define("F_FONT", "myfont.ttf");
    $img = imagecreate(WIDTH, HEIGHT);
    $white = imagecolorallocate($img, 255,255,255);
    $black = imagecolorallocate($img, 0,0,0);
    $start_x = 10;
    $start_y = (int)HEIGHT/2;
    $text = "PHP Unleashed";
    imagerectangle($img, 0,0,WIDTH-1,HEIGHT-1, $black);
    imageTTFtext($img, F_SIZE, F_ANGLE, $start_x,
                 $start_y, $black, F_FONT, $text);
    header("Content-Type: image/png");
    imagepng($img);
?>
