Hi @afherrerac ,

What format is the uploaded image? Here is the Link to the supported file formats for the Image widget.

 

It is base64 the case is have downloaded an image via rest api the idea is to show it

Hi @andreherrerac95 ,

 

Could you please share the project with me for testing. I highly appreciate it if you could share the project zip file.

 

Thank you!

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
