How to use GIFDecoder.class.php

Hello László Zsidi,

First of all, thank you for your superb class !

I have a little problem with GIF decoder, during the extraction of a frame, transparency native GIF is not retained.

Is it possible to solve this problem ?

Thank you

Hi there. The tool sound nice, but the quality is not that good, try out the spillter with this gif:

livesystems.ch/media/animated.gif

any idea?

Hi - thanks for writing this class!

My issue is that while it works, the images are really poor quality when they're split. For example, take a 5 second a movie sequence which looks fine online as an animated gif. I download it to my desktop, upload it through my website and when the GIFDecoder splits it, all the images are black and white, and all noisy. I tried a cartoon animated gif which had a white background, and when I decoded it the background turned blue.

Any ideas? I'm using version 2.0 (Updated at 2009. 06. 23. '06.00.AM').

Thanks!

Thank you a lot! Really exciting class! Thank you!

I don't know whether this is the right place to ask this question. Sorry if I am in the wrong place. I uploaded the sample as it is. But I am getting following error when run Example.php

GIFEncoder V2.05: 13 Source is not a GIF image!.

Any ideas?

To be sure that the source images are in gif format.
Gifencoder accept gif source images only.

Dear László,

Thank you. It works great. I came across a small problem. when I make the animated gif with photos, areas entirely black becomes entirely white.

Should I save gif frames in a particular gif format?

Thanks

Just wanted to post the solution to a problem that took me quite a few hours to solve: I wanted to create an animated GIF where one frame was dynamically generated by PHP with custom text on it. This would not work because even though I used

header("Content-Disposition: inline; filename=filename.gif");

to set the correct filename format, it was still not recognized as a gif file (GIFDecoder returned "Source is not a GIF image").

The solution: I managed to solve the problem by changing the GIFEncoder source type to 'bin' instead or 'url' and loading the image content using 'file_get_contents'. After I finally figured out a space in the GET variables of the URL was causing the 'false' I kept getting I added 'urlencode' to those variables and it all worked like charm! :)

I used this code but it isn't working.
I have this message:
Notice: Uninitialized string offset: 10 in C:\Arquivos de programas\EasyPHP-5.3.7RC5\www\gif\GIFDecoder.class.php on line 166

And the count of the array always return 0.
Can u help me?

it seems gifdecoder incorrectly split gif into frames there are wrong order of splitted frames. are there any solution of this problem?
