[RESOLVED] Error during Image Creation

Felix2

Whenever I try to create an Image either from another Image or directly using the GD Library it results in errornous image code.

Even when just opening an image and then displaying it with the imagepng() function results in nothing that could be used:

‰PNG IHDRºq¤PLTEÿâ 7*IDATxœíÁ1Â õOío €7O°9—xIEND®B`‚

That is the result of :

<?php
$im = imagecreatefrompng("test.png");
imagepng($im);
imagedestroy($im);
?>

Yes I defined the meta type in the header.

I'm using PHP5 running as an Apache 2 module with the gd2 library as extension.

phpinfo() sais this:

gd
GD Support enabled
GD Version bundled (2.0.28 compatible)
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.1.9
T1Lib Support enabled
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

The browsers used to test this are : Firefox 1.5.0.6 and IE 6

Interesting to note though is that it saves the image right when its selected to save it to a file and then display it. But just displaying it results in the error.

Ok then if anyone can help me I'll be very glad = )

If you need any additional information feel free to ask

You did? Really? Where?

<?php
$im = imagecreatefrompng("test.png");
imagepng($im);
imagedestroy($im);
?>

Nowhere in that code do I see an image content type being set.

I directly set that in the surrounding HTML I tried it with setting the header with the PHP script aswell but that didn't work but I'll post what I wrote when I set it with the
script:

<?php
header("Content-type: image/png");
$im = imagecreatefrompng("test.png");
imagepng($im);
imagedestroy($im);
?>

Which results in the same

Surrounding HTML? If you're outputting an image, you can't have anything else displayed in this script. Besides, you can't set an HTTP header in HTML.

In otherwords, this:

<?php
header("Content-type: image/png");
$im = imagecreatefrompng("test.png");
imagepng($im);
imagedestroy($im);
?>

should be the ONLY thing in the entire .php file. A single space outside of the <?PHP ?> tags will more than likely kill the entire thing.
