Hello

imagecolorat works incorrectly with imagecreatefromgif and imagecreatefrompng
and it works with imagecreatefromjpeg

Here is working code:
<?php
$im = imagecreatefromjpeg("Capture.jpg");

$rgb = imagecolorat($im,10,10);

echo $rgb;

$r = ($rgb >> 16) & 0xFF;
$g = ($rgb >> 8) & 0xFF;
$b = $rgb & 0xFF;

echo $r."_".$g."_".$b;

?> 


Sincerely,
Dmitry


Reproduce code:
---------------
<?php
$im = imagecreatefromgif("Capture.gif");

$rgb = imagecolorat($im,10,10);

echo $rgb;

$r = ($rgb >> 16) & 0xFF;
$g = ($rgb >> 8) & 0xFF;
$b = $rgb & 0xFF;

echo $r."_".$g."_".$b;

?> 


Expected result:
----------------
255_255_255 on white color, when use imagecolorat with jpg


Actual result:
--------------
0_0_106 on white color, when use PNG imagecreatefrompng) or imagecreatefromgif(with GIF  file)
