首先，我会保留默认的大小调整工具，因为在某些情况下它可能会派上用场.我所做的是添加了两个功能来调整图像大小.

First of all I would leave the default resizing tool as in some circumstances it might come in handy. What I did was add two more functions to resize images.

一个功能可以裁剪图像，使其适合管理员设置的尺寸.现在添加了空白区域.这是伟大的产品清单.我添加的第二个功能是调整图像大小的功能，因此最大尺寸将设置为在管理员中设置的最大尺寸.它将按比例缩放.

One function that crops an image so it fits the size set in the admin. Now empty white areas are added. This one is great for product lists. The second I added is a function that resizes an image so the biggest dimension will be set to the max size set in the admin. It will be scaled proportionally.

我将两个额外的功能命名为 cropsize 和 onesize .您要做的就是在控制器中找到使用的调整大小功能并进行以下调整:

I named the two extra functions cropsize and onesize. All you have to do is find the used resize functions in the controller and adjust this:

'thumb' => $this->model_tool_image
                ->resize($image, 
                         $this->config->get('config_image_category_width'), 
                         $this->config->get('config_image_category_height')));

收件人:

'thumb' => $this->model_tool_image
                ->cropsize($image, 
                           $this->config->get('config_image_category_width'), 
                           $this->config->get('config_image_category_height')));

onesize函数仅需要一个参数，因此由您自己决定，但是您可以使用类似以下的方法:

The onesize function only needs one parameter so it's up to you but you could use something like this:

'popup' => $this->model_tool_image
                ->onesize($result['image'], 
                          $this->config->get('config_image_popup_width'))

我希望这会帮助您获得更好的图像.

I hope this will help you getting better images.
