Description:
------------
When using ImageColorAt to find the color of a pixel within an image it returns the correct value in IE & Mozilla, but in Opera its null. It appears to not be dependant on the format of the resource image.

Reproduce code:
---------------
$rgb = ImageColorAt($im, $x, $y);

Expected result:
----------------
$rgb should contain the values of the pixel at those coordinates.

Actual result:
--------------
$rgb is null.

Sorry, but that is simply not possible.  PHP is server-side and is in no way affected by the type of browser sending the request in a function like ImageColorAt assuming the image in question is the same under all the browsers.  Your error must be elsewhere.
