Bizarre output of image when using GD

[arafin]

Hello

Is there anyone to help me? I have PHP 5.0.4 and from php.ini I know :

GD Support enabled

GD Version bundled (2.0.28 compatible)

FreeType Support enabled

FreeType Linkage with freetype

FreeType Version 2.1.9

GIF Read Support enabled

GIF Create Support enabled

JPG Support enabled

PNG Support enabled

WBMP Support enabled

XBM Support enabled

But when output a line or anything related image with GD then I see some bizzire output like :

GIF87aÈÈ¡ÿÿÿÿÿÈÈÈ,ÈÈþœ©Ëí£œ´Ú‹³Þ¼û†âH–扦êʶî ÇòL×ö

Please HELP me. I badly need it.

Yes, read the php manual for images image functions . Be sure to check out the examples. Most likely your not setting the header to display the image.

header("Content-type: image/gif");

Yes, you're outputting a GIF file and trying to render it as HTML. (Dead giveaway is the GIF file format magic number "GIF87" at the start). You either forgot to use the header() function or you're trying to stick binary data into a page instead of linking to it with an <img> tag.

Thanks for your reply. I have run this following program:
<?php
header ("Content-type: image/png");
$img_handle = ImageCreate (230, 20) or die ("Cannot Create image");
$back_color = ImageColorAllocate ($img_handle, 0, 10, 10);
$txt_color = ImageColorAllocate ($img_handle, 233, 114, 191);
ImageString ($img_handle, 31, 5, 5, "My first Program with GD", $txt_color);
ImagePng ($img_handle);
?>

And still the same output

‰PNG IHDRæ£þÓêPLTE ér¿ŽLÚIDATxœåбAàŸMhF®!ža’+(„WÙË&ª;‘xë”Z…‡Ði'J*D£RÑ+®0wÁ¯«ÙýòÏfø³Sc CYeŸGEý˜õà«*T,(´ªšðñ£Peí|&H»;?&¦±éÖ³½54IÇ%¥öÉé¿×‘[¢•!‘i¡)1kg$;ÇP E‚˜o™¶²,{»—z÷·†…Âå:Ž¾´¹Ì”¨Ž,³fSñƒ8Ÿ¨Æ7Ȑ½íEµ¯E´ª,ÒNçÛ@µ4&‚øg••Gé2ü¶'€£D?ijžIEND®B‚

What can I do now?

[Weedpacket]

Well, I'd expect that to work unless you're buffering output somewhere, and you're putting out something else before you get to the above code. Is that all there is in the file?

Try this, see if it dies at the message:

<?php
$file=$line='';
if(headers_sent($file,$line))
{
   die("Shouldn't have got here, but headers have already been sent (in file $file, at line $line).");
}
header ("Content-type: image/png");
$img_handle = ImageCreate (230, 20) or die ("Cannot Create image");
$back_color = ImageColorAllocate ($img_handle, 0, 10, 10);
$txt_color = ImageColorAllocate ($img_handle, 233, 114, 191);
ImageString ($img_handle, 31, 5, 5, "My first Program with GD", $txt_color);
ImagePng ($img_handle);
?>

🙂 Thanks Weedpacket. It works. It works only if the above code is only in the file without any html. But if I include the code in a html file what shall I do?

[samudasu]

Save your image code in a file and name it image.php or something. In your html file where you want to display the image, add this line <img src="image.php">. Read the PHP Manual for image functions. Read example 1. and the paragraph below it on this page. image functions

As I suggested in my original reply. It's like people never fully read those things 🙂
