imagepng(); Error

Rhymhoont · February 28th, 2007, 02:29 PM

I have the following code:

<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Test Site</title>
</head>
<body>
<?php
 $MyImage = imagecreate(200,100);
 $MyGrey = imagecolorallocate($MyImage,204,204,204);
 $MyBlack = imagecolorallocate($MyImage,0,0,0);
 imageline($MyImage, 15, 35, 120, 60, $MyBlack);
 header("content-type: image/png");
 imagepng($MyImage);
 imagedestroy($MyImage);
?>

 
Test Page

</body>
</html>

When I run this, I get the following:

â°PNG IHDRÃdÃ¹HÃHPLTEÃÃÃÃ33dMIDATxÅc`Â£` ÃxÂ§â Nf*kÂ²Ã)ÃÃ¸Â§ââ¢5}Ã)ÃÂSâ ÂÃÅ¡pJUÃ â aÂ§Â²Â¦Å2ÃÅ½w<Å¡pJÂâQ0 â ;Â u%ÃÃ¦ÃIENDÂ®B`â

Why is it not displaying the image instead of the code?

PHP v. 5.1.4
in phpinfo();

Hi Rhymhoont,

Try to create a seperate file for your image creation:

image.php
---------
<?php
 $MyImage = imagecreate(200,100);
 $MyGrey = imagecolorallocate($MyImage,204,204,204);
 $MyBlack = imagecolorallocate($MyImage,0,0,0);
 imageline($MyImage, 15, 35, 120, 60, $MyBlack);
 header("content-type: image/png");
 imagepng($MyImage);
 imagedestroy($MyImage);
?>

index.php
---------
<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Test Site</title>
</head>
<body>
<?php
include('image.php');
?>

 
Test Page

</body>
</html>

When I look at the code of your image-creation I note that the header (header("content-type: image/png"); ) doesn't correspond with the header of your file (<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">). Perhaps this will solve your problem?
