To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2004-05-22 17:00:42] philippe dot nonn at capgemini dot com Description: ------------ Using the las version of Graphical Library PHP_GD2 leads to display images which are only partially filled when using the function ImageFillToBorder. It looks like only the upper part of the zone which should be filled gets the selected color. The problem doesn't appear when using le 4.3.5 version of php_gd2. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28490&edit=1
