Question

在phal中使用GD Adapter，我的代码示例是这样的。它正确调整图像大小但不是预期的。如果它的宽度超过458px，我想调整图像大小，这种情况下它工作正常，但如果它低于457px它不应该调整它应该保持原样。但我的脚本总是调整任何大小的图像是什么错？拜托！

if($this->request->hasFiles(true) == true)
{
    foreach ($this->request->getUploadedFiles() as $file)
    {
        #Required enable extension=php_fileinfo.dll in php.ini
        if ($this->imageCheck($file->getRealType()))
        {
            //echo $file->getName(), " ", $file->getSize(), "\n";
            $imgName = md5(uniqid(rand(), true)).strtolower(date('-dmy-').$file->getName());
            $file->moveTo('uploads/blogs/' . $imgName);
            #Resize & Crop Image
            $image = new GdAdapter('uploads/blogs/'.$imgName);
            $image->resize(458,458)->crop(457,457)->save('uploads/blogs/'.$imgName);
            $blog->bimage = $imgName;
        }
        else
        {
            $this->flashSession->error("File extension not allowed");
            return $this->response->redirect($this->router->getControllerName());
        }
    }
}

你必须添加一个关于图像宽度的条件。类似的东西：

  $image = new GdAdapter('uploads/blogs/'.$imgName);
  if ($image->getWidth() > 458) {
      $image->resize(458,458)->crop(457,457)                    
  }
  $image->save('uploads/blogs/'.$imgName);
