[RESOLVIDO] Gerar GIF animado

[brcontainer 16]

Eu gostaria de saber se há algum jeito de ler uma imagem "GIF ANIMADO"

Em PHP e mudar o tamanho dela sem perder a animação???

 

tipo eu sei gerar "thumbs" com PHP ex:site.com/thumb.php?imgagem.gif

porem elas perdem a animação

 

 

Tem algum jeito de fazer com animação??? http://forum.imasters.com.br/public/style_emoticons/default/natal_tongue.gif

 

Please respostas

Até onde eu sei: NÃO

A biblioteca GD nem suporta mais gif...

ae é só eu fazer com que esses frames que foram salvos na pasta "FRAMES" sejam reduzidas

isso é facil :P

 

e com essa classe eu junto os frames:

Sim, realmente estas 2 classes são muito boas e funcionam perfeitamente para fazer isso que você quer. Por sinal eu também fiz um script parecido, onde redimenciono automaticamente os avatares que os usuários enviam para o site.

 

Só tem um problema aí.

 

Quando os usuários enviam gifs animadas com fundo transparente para usar como avatar, a classe que quebra a gif em frames faz com que esses frames percam a transparência e aí quando junto novamente o gif ele não ta mais com o fundo transparente.

 

Caso alguém tenha uma solução para isso eu agradeceria pois já estou quebrando a cabeça há alguns dias nisso e ainda sem solução.

 

Eu até postei uma mensagem no fórum dessa classe do cara lá no phpclasses.org mas até agora ele não respondeu. (http://www.phpclasses.org/browse/package/3234.html)

 

É isso aí.

 

Valeu

Olá amigos, está apresentando o seguinte erro na classe que junta os frames:

"Parse error: syntax error, unexpected '!' in ... on line 128"

 

Se alguém souber e puder postar a solução ficarei grato!
