converting html to image not working

Question

I use this script to make html code into image using php-gd library:

<?php
    //put your html code here 
    $html_code = ' 
    <html> 
        <body> 
            Image Out Put sadadasdasdasdasdasd
        </body> 
    </html>
    '; 

    $img = imagecreate("300", "600"); 
    imagecolorallocate($img,0,0,0); 
    $c2 = imagecolorallocate($img,70,70,70); 
    imageline($img,0,0,300,600,$c2); 
    imageline($img,300,0,0,600,$c2); 

    $white = imagecolorallocate($img, 255, 255, 255); 
    imagettftext($img, 9, 0, 1, 1, $white, "arial.ttf", $html_code); 

    header('Content-type: image/jpeg'); 
    imagejpeg($img); 

?>

What do you mean with _unknown char_? How do you expect this to work? — putvande, Oct 15 '13 at 12:30
The `Content-Type` header is not sent properly. The Document has the Content-Type `text/html`. — Le_Morri, Oct 15 '13 at 12:31
OP is trying to create an image so that is not the correct `Content-Type` @Le_Morri — putvande, Oct 15 '13 at 12:32
Thats what I am saying. his given code is right. But the server is not doing it. — Le_Morri, Oct 15 '13 at 12:35
Do you have the file 'arial.ttf' in the same folder as your PHP script? — putvande, Oct 15 '13 at 12:37
I downloaded the link provided removed 1 space and 2 carriage returns and saved back. you can see the image. black background with white text and a diagonal cross across the image — bansi, Oct 15 '13 at 12:42

You have unwanted chars before <?. remove all blank lines and spaces before <? your image is otherwise correct.

<? must be the first character first line in your script. you can avoid ?> if you use it it must be the last line last chars.

Please make sure that your file start without spaces or extra chars. It is important that it starts with

<?

You can avoid the closing

?>

So that you're sure to not send any other unwanted output to the client.

Make sure you have the GD library enabled on your server.
You should use png instead of jpg as png produces better text quality
You should use imagedestroy after imagejpeg or imagepng to clean up memory
