Hi @andreherrerac95 ,

the received data is base64 so you do not need to encode it.  For pictures some thing like this:

 

$http(req).then(
function(response) 
  
  { //here you need to pay attention about the correct type jpg, gif, png 
    var ret_str='data:image/gif;base64,'+response.data.rows[0].Content;
     console.warn(ret_str);
     $scope.view.wdg[image_id]['imgsrc']=ret_str; //2d image
//  $scope.view.wdg[image_id]['src']=ret_str; //3d image
     }, 
function(response){;}
               );
};

 

So this is all. you need to set the src /imgsrc for 3d/2d images property of the image widget
