<?php
$im = imagecreatefrompng('nexen.png');
$start_x = 40;
$start_y = 50;
$color_index = imagecolorat($im, $start_x, $start_y);
$color_tran = imagecolorsforindex($im, $color_index);
print_r($color_tran);
?>
The above example will output
something similar to:
Array
(
[red] => 226
[green] => 222
[blue] => 252
[alpha] => 0
)
imagecolorset
