codeigniter在嵌入水印後裁剪

Question

我在這裏遇到了一些麻煩，我想通過裁剪和水印圖像上傳我的圖像。這裏是我的控制器代碼

//cropping image 
$img['maintain_ratio'] = FALSE; 
$img['create_thumb'] = TRUE; 
$img['width'] = $thumb_size; 
$img['height'] = $thumb_size;    
$this->image_lib->initialize($img); 
$this->image_lib->crop(); 
$this->image_lib->clear(); 
$img['source_image'] = $source ; 

//watermark image 
$img['new_image'] = $destination_thumb ; 
$img['wm_overlay_path'] = './images/resource/watermark.png'; 
$img['wm_type'] = 'overlay'; 
$img['wm_vrt_alignment'] = 'midle'; 
$img['wm_hor_alignment'] = 'center'; 
$this->image_lib->initialize($img); 
$this->image_lib->watermark();    
$this->image_lib->clear() ; 

的所有代碼是罰款沒有發現錯誤，代碼只是創建水印不裁剪，但是當我扭轉上述裁剪代碼的水印編碼，結果只有剪切圖像。

那麼我需要做什麼，我可以上傳圖像與裁剪和水印一次？

在此先感謝

你可以試試這個：

$img['source_image'] = $source ; 

$img['maintain_ratio'] = FALSE; 
$img['create_thumb'] = TRUE; 
$img['width'] = $thumb_size; 
$img['height'] = $thumb_size;    
$this->image_lib->initialize($img); 
$this->image_lib->crop(); 
$this->image_lib->clear(); 


//watermark image 
$img['new_image'] = $destination_thumb ; 
$img['wm_overlay_path'] = './images/resource/watermark.png'; 
$img['wm_type'] = 'overlay'; 
$img['wm_vrt_alignment'] = 'midle'; 
$img['wm_hor_alignment'] = 'center'; 
$this->image_lib->initialize($img); 
$this->image_lib->watermark();    
$this->image_lib->clear() ;
