Congratulation for the great class!

It was easy to install, thanks to your instructions, and worked immediately, without any hassle.

However, the only thing I didn't manage to do is set the transparence. My original files have transparency, but not the result.

I have tried several versions of the class, including the one on gifs.hu which is called £.0.

The transparent colour is black (0,0,0), the files are:

services.tagopedia.info/text/frames ...
services.tagopedia.info/text/frames ...
services.tagopedia.info/text/frames ...
services.tagopedia.info/text/frames ...
services.tagopedia.info/text/frames ...

and the resulting (non transparent file) is:

services.tagopedia.info/text/frames ...

I would be very grateful if you could help. Many thanks in advance!

Regards
V

thats not the problem! the problem is the frame which is just transparent. insert a black pixel in a corner and it works... maybe this can be fixed in the new version?

I am using the last version, but there is a very strange thingy - transparancy does not work for the binary mode:


$gif = new GIFEncoder (
$frames,
$framed,
0,
2,
0, 0, 0,
"url"
);

this one works, but as soon as I generate images as binary and set:

$gif = new GIFEncoder (
$frames,
$framed,
0,
2,
0, 0, 0,
"bin"
);

it is not working. The script works just fine... but no transparancy :(. Any ideas?

gifs.hu site has been closed temporary, i will reopen the site on a new server with new versions of GIFDecoder and encoder classes.
i feel that classes are good but not perfect maybe the classes have some problems yet.
please, if you have any problem ( except transparency problem ) then you write me an email ( [email protected] ) and i will try to resolve it.
i will write here when my site i reopened, and be ready to download the new version of GIFEncoder. ( i hope without errors )
