[practicalsoft]

Hi All,

I am trying to implement a QR code generator on the server side, I am using the library from @tchart in the link below:

I am using EncodeTextToPNG as I want to have an image that I can insert into a PDF but I am getting an error: javax.imageio.IIOException: Can't create an ImageOutputStream!

Below is the line of code that is creating the error.
B4X:

qr.EncodeTextToPNG(TheqrImage,File.DirApp & DownloadFolder,SignaturAgent)

Is there something that I am doing wrong

Kind Regards Christopher
