操縱與ImageMagick庫圖像笨

Question

我希望你們能幫助我與我的代碼走的更遠，是因爲我卡住。在編寫代碼時，我完全迷茫了自己，所以我需要一點幫助，在當前的實現中有什麼可能，哪些不是。

因此，這裏是我的笨代碼，上傳圖片，並試圖與這些文件操作。

public function addImagesToProduct_post(){ 
     $id_product = $this->input->post('id_product'); 

     $data = array(); 
     $count = count($_FILES['files']['size']); 
     foreach($_FILES as $key=>$value) { 
      for ($s = 0; $s <= $count - 1; $s++) { 
       $_FILES['userfile']['name'] = $value['name'][$s]; 
       $_FILES['userfile']['type'] = $value['type'][$s]; 
       $_FILES['userfile']['tmp_name'] = $value['tmp_name'][$s]; 
       $_FILES['userfile']['error'] = $value['error'][$s]; 
       $_FILES['userfile']['size'] = $value['size'][$s]; 
       $config['upload_path'] = $_SERVER['DOCUMENT_ROOT'] . "/images/"; 
       $config['allowed_types'] = 'jpg|jpeg|png'; 
       $config['max_width'] = 1920; 
       $config['max_height'] = 1080; 
       $config['remove_spaces'] = TRUE; 
       $this->upload->initialize($config); 
       if($this->upload->do_upload()){ 
        $currentImage = $this->upload->data(); 
        $this->load->library('image_lib'); 
        $imgConfig['image_library'] = 'ImageMagick'; 
        $imgConfig['source_image'] = $currentImage['full_path']; 
        $imgConfig['create_thumb'] = TRUE; 
        $imgConfig['thumb_marker'] = TRUE; 
        $imgConfig['maintain_ratio']= TRUE; 
        $imgConfig['width']   = 1024; 
        $imgConfig['wm_text'] = 'MY watermark'; 
        $imgConfig['wm_font_size'] = '32'; 
        $imgConfig['wm_vrt_alignment'] = 'bottom'; 
        $imgConfig['wm_hor_alignment'] = 'right'; 
        $imgConfig['wm_padding'] = '20'; 
        $imgConfig['wm_type'] = 'text'; 
        $this->image_lib->initialize($imgConfig); 
        $this->image_lib->watermark(); 
        /////////////////////////// 
        //// SAVE STUFF TO DB ///// 
        /////////////////////////// 
        $data['imgData'] = $this->upload->data(); 
        $data['success'] = true; 
       }else{ 
        $data['messageErrorAddPicture'] = str_replace("<p>", '', str_replace("</p>", '', $this->upload->display_errors())); 
        $data['addImageFail'] = true; 
        $data['success'] = false; 
       } 
       echo json_encode($data); 
      } 
     } 
     //echo json_encode($data);  
    } 

我的目標（寫，如果可能在我目前的執行情況和提供例如請）：
1.上傳圖像，而不是更大然後HD
2.壓縮當前上傳的圖片是小於100KB
3.將圖像大小改爲最大寬度1024 x 786（但如果用戶拍攝垂直放置的圖片，會發生什麼情況？）
4.創建當前圖像的縮略圖
5.設置縮略圖大小爲250 x 250
6.將它放在拇指文件夾下（其中在裏面的圖像文件夾）

我的問題是：
1.如何壓縮當前圖像小於100kb？
2.如果我將當前圖像調整爲1024寬度，如何處理垂直圖像？
3.如何指定縮略圖大小和商店位置？

如果您需要任何額外的信息，請讓我知道，我會提供。謝謝你在前進

我終於設法使它工作。 這就是我的控制器現在的樣子
