Eu usei de tudo, ... maintain_ratio, master_dim... nada funcionou... agora
mando a largura e calculo a largura... proporcional através da imagem
enviada...
$up = $this->upload->data()ç
$nome = mdate("%Y%m%d_%H%i%s%u", time()) . $up['file_ext'];
$imagem['image_library'] = 'gd2';
$imagem['new_image'] = $upload['upload_path'].$nome;
$imagem['source_image'] = $upload['upload_path'].$up['file_name'];
$imagem['maintain_ratio'] = TRUE;
$imagem['width'] = 450;
$imagem['height'] = ($imagem['width'] * $up['image_height']) /
$up['image_width'];
$this->image_lib->initialize($imagem);
$this->image_lib->resize();
$this->image_lib->clear();
Espero ajudar...
