Codeigniter圖像裁剪不起作用

Question

我在本地主機上使用codeigniter 3.1。 我想裁剪圖像，但裁剪不工作。只調整工作。所以我啓用了Gd2 php擴展。

1.

public function do_crop($filename) 
{ 
    $this->load->library('image_lib'); 
    $source_path = 'uploads/' . $filename; 
    $target_path = 'uploads/thumb/'.$filename; 

    $config = array(
     'image_library' => 'gd2', 
     'source_image' => $source_path, 
     'new_image' => $target_path, 
     'maintain_ratio' => FALSE, 
     'x_axis' => 300, 
     'y_axis' => 100, 
    ); 
    $this->image_lib->initialize($config); 
} 

圖像大小= 1000X700

輸出結果是一樣的原始圖像大小1000X700

2.

public function do_crop($filename) 
    { 
     $this->load->library('image_lib'); 
     $source_path = 'uploads/' . $filename; 
     $target_path = 'uploads/thumb/'.$filename; 

     $config = array(
      'image_library' => 'gd2', 
      'source_image' => $source_path, 
      'new_image' => $target_path, 
      'maintain_ratio' => FALSE, 
      'width' => 300, 
      'height' => 300, 
      'x_axis' => 350, 
      'y_axis' => 50 
     ); 
     $this->image_lib->initialize($config); 
    } 

圖像大小= 1000X700

而第二示例僅調整（300x300）中的圖像但不裁剪。

Answer 1

$config = array(
'source_image' => $upload_path.$image_data['file_name'], 
'maintain_ratio' => FALSE, 
'width' => 220, 
'height' => 150, 
'x_axis' => 350, 
'y_axis' => 50 
); 
$this->image_lib->clear(); 
$this->image_lib->initialize($config); 
$this->image_lib->crop();
