我试图在不裁剪的情况下调整用户上传的图像大小。为此，我使用以下代码。

$config['image_library'] = 'gd2';
    $config['source_image'] = './uploads/'.$name.'.jpg';
    $config['new_image']    = './uploads/'.$name.'.jpg';
    $config['create_thumb'] = TRUE;
    $config['maintain_ratio'] = TRUE;
    $config['width']     = 75;
    $config['height']   = 50;
    $this->image_lib->resize();
    $config['new_image']    = './uploads/'.$name.'.jpg';
    $config['width']     = 1000;
    $config['height']   = 400;
    $this->image_lib->initialize($config);
    $this->image_lib->resize();

但问题是它没有给我1000x400的图像尺寸。它给了我尺寸为534x400的图像。有什么办法可以克服这个问题吗？

将$config['maintain_ratio'] = TRUE;更改为 $config['maintain_ratio'] = FALSE;

将此属性更改为

$config['maintain_ratio'] = 假;
