CodeIgniter调整图像大小

Question

我的脚本是：

public function resize_image($dir, $new_name, $image, $width, $height)
{
$img_cfg_thumb['image_library'] = 'gd2';
$img_cfg_thumb['source_image'] = "./" . $dir . "/" . $image;
$img_cfg_thumb['maintain_ratio'] = TRUE;
$img_cfg_thumb['new_image'] = $new_name;
$img_cfg_thumb['width'] = 200;
$img_cfg_thumb['height'] = 200;
$this->load->library('image_lib');
$this->image_lib->initialize($img_cfg_thumb);
$this->image_lib->resize();
}

但它只会创建 200 x 150

的缩略图

Answer 1

您的原始图片尺寸是多少？

因为

 $img_cfg_thumb['maintain_ratio'] = TRUE;

尝试将其设置为false
