Hi,

In our mobile app we have local entity with binary field. We want to use this image as base64 string for google maps marker. 

I've tried btoa($parameters.image) but result string is not a valid base64 image. Also I've tried

var reader = new FileReader();
  binarystring = reader.readAsBinaryString($parameters.image);
$parameters.base64 = btoa(binarystring);

but that doesn't recognize  $parameters.image as blob.

While viewing data on developers tools it seems that data is actually stored as base64 string... But I can't assign the value directly to my icon as it requires text instead of binary.... 

I would appreciate any suggestion of how to work this out.

Thank. you.

Hi,

Checks if this component solves your issue:

https://www.outsystems.com/forge/component/287/extension-base64/

If not try to do with extension (C#):

using (Image image = Image.FromFile(Path))
{
    using (MemoryStream m = new MemoryStream())
    {
        image.Save(m, image.RawFormat);
        byte[] imageBytes = m.ToArray();

        // Convert byte[] to Base64 String
        string base64String = Convert.ToBase64String(imageBytes);
        return base64String;
    }
}

Hi, This component is working fine but on server side. 

For our purposes we need client side conversion. However it might be a solution - assign binary value to text inside JS Node as binary field in local storage is actually a base64 string.

Hi Mykola,

Did you already try just doing $parameters.base64 = $parameters.image  ?

Edit: oops looks like I took too long writing the reply, yeah is like you said :P
