Hi,
short question:
Im using GD to generate some gif's.
How do i change all colors within a certain area of the image -
e.g. rise the brightness.
Perhaps there is a way to rotate the pallet or draw a transparent white
layer (background color) over the area, which creates this effect? Or
multiply two images, or whatever...
I have to create some color gradations, but cannot use a fill method,
because there's no way to determin
the position of the objects. finally a new object is drawn, the image is
written, an the next time the program starts,
the process starts again. So these obects fade out afer x turns.

Did you try the copyMerge method (in particular the percent value for
opacy)?

thanks for the help. turns out it's as simple as passing
CallMySub ( [$cookie1, $cookie2, $cookie3] , $new_url);
then in the sub:
my ($cookies, $new_url) = @_;
print $q->redirect(-cookie=>$cookies,-uri=>$new_url);
