OBRIGADO!

Matias Rezende · Outubro 26, 2009

Certo, mas qual a dúvida? Tentou fazer e apresentou algum erro? Como tentou fazer a utilização da classe?

Carlos Eduardo

britgame · Outubro 26, 2009

Então Carlos...tentei de várias formas encontrar nas funções acima a varialvel q eu devo colocar + não tive sucesso nenhum... está tudo dependendo dessa linha:

$this->workingImage = imagerotate($this->oldImage, $degrees, 0);

Eu consegui usa-la separadamente + preciso colocá-la nessa classe para que outras classes da developertoolbox, como a de deletar os thumbnails, funcionem corretamente.

Cara sei q eu estou bem perdido, é até dificil pra explicar minha dúvida...por isso minha esperaça é a experiencia d vcs.

obrigado...

Matias Rezende · Outubro 26, 2009

Olha, como você quer usar a Developer Toolbox, talvez o pessoal do fórum de Dreamweaver saiba ajudar melhor.

Quer que mova pra lá?
