Hello,

everytime I'm using the GIFEncoder constructor with 'C_FILE' as last parameter, I get the following error :

GIFEncoder V2.05: Unintelligible flag ( C_FILE )!

So, I replaced 'C_FILE' with 'url'. Still, nothing is displayed in the following example (I checked my $frames and &framed arrays, they are ok) :

########################################################
$frames = array() ;
$framed = array() ;

if ( $dh = opendir ( "img/en/banner/" ) ) {
while ( false !== ( $dat = readdir ( $dh ) ) ) {
if ( $dat != "." && $dat != ".." ) {
$frames [ ] = "img/en/banner/$dat";
$framed [ ] = 3;
}
}
closedir ( $dh );
}

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

Header ( 'Content-type:image/gif' );
echo $gif->GetAnimation ( );
########################################################

can you help me please, I really need to have animated gif in php.

thanks in advance,


jim

Hi,

The newest GIFEncoder have difference parameter for source than the older GifMerge versions.
The older versions uses "C_MEMORY" for binary data and "C_FILE" for url data, the newest version uses "bin" for binary data and "url" for url data.
This parameter is not case sensitive.

Do you want a complete new documentation for GIFEncoder?

Regards,
László

I thought to be sure that the playing of animations has been enabled by your browser.
Or try to write content into file /* fwrite ( fopen ( "myanimation.gif", "wb" ), $gif->GetAnimation ( ) ); */ and check the content of generated file.

Waiting for your reply.

Regards,
László

Hi László,

> Do you want a complete new documentation for GIFEncoder?

if there are any important other things to know about the use of this class, it would be kind of you :-)

I tested on Opera 9, Firefox 1.5 and Internte Explorer 6.
results :
Opera 9 : blank page (no error, no image)
Firefox 1.5 : an empty image with the broken link icon and the message "The image 'http://localhost/test.php' cannot be displayed, because it contains errors."
Internet Explorer 6 : an empty image with broken link icon.

> Or try to write content into file /* fwrite ( fopen ( "myanimation.gif", "wb" ), $gif->GetAnimation ( ) ); */ and check the content of generated file.

I get a valid Gif image with only the first frame (no animation). My animated gif should have had 3 frames.


Thank you for your help !

I'm interested in the full documentation, in order to use your class at its full potential...

Where can I get the latest version of these? I tried gifs.hu, but that is the same version as PHPclasses.

I have the same problem. I am simply trying to repeat the demo at phpclasses, using those GIF files. This has nothing to do with the browser, I believe, it is the reading which is a problem.

Actually, the problem is not at all in GIFEncoder, it's the Example.php stashed at the phpclasses site. That example passes 'C_FILE' as a parameter to the constructor, not the 'url' as it should.

With that correction this works just fine.

I am interested in more extensive documentation, however.

Hi,

I'm so sorry, but I am very busy.
The last working version of GIFEncoder can be found at phpclasses.org or http://gifs.hu/phpclasses/show.php?src=GIFEncoder.class.php ( 2.05, with on-line working demo )
The constructor flag for sources has been changed in the new GIFEncoder version.
Mast be used "url" flag instead of "C_FILE" and "bin" instead of "C_MEMORY".
These flags are not case sensitive.
Documentation is under rewriting permanently.
