Transform a Gif to PNG or JPG without NetPbm or anything else

Hi,
does anybody now how to transform a gif, in png ?

I explain myself : I use shared servers, so i only have gd to
transform images.

Sometimes, i have netpbm, but not at this time.

As GD >1.6 does not support Gif format (only reading), i want to
transform gif in png. But how to do this without specific library
(gif2png for example) ?????

Is there any body who solve this problem ?????

Thanks for yours answers.

Actually, one of the patents expired this summer and I know the other
expires this year as well (not sure if it has yet). Not that I think that
GIF support will be added back into GD. GIF is obsolete and inferior, would
be a waste of time.

The author of GD says on his page that GIF will go back in next year when the
final patent runs out.

In the mean time the question has gone unanswered and somewhat ignored.
He's asking how to convert to PNG. Personally i don't know, so there's
my answer. i hope someone else has a better one.

GIF to PNG is fine, since (at least the PHP-bundled GD) has read-only GIF
support.

ImageCreateFromGif followed by ImagePng.

<?php
$im = imagecreatefromgif('circle_1.gif');
imagepng($im);
?>

Just tried it with the bundled 2.0 GD library, worked fine.

It's the other way around that can't be done.

Thanks for this example.
I'm surprised, because, i've already done this, but i always had a
message like bad Format ........

But in fact with time and distance, and thanks to Andy i implent again
my code, and it's working ! Cool.

For the waste of time of KHA : When your customer need Gif, he need
Gif, and you can't say "excuse me But Gif is too Uggly, use PNG".

This is the business Law.

Really thanks for your contributions....

Kind regards
