Question

User-829096311 posted

Hi

I have an api site that returns image as shown in the following code
The question is how can I add a some info to the image like  version number or a short text for reading it in client side. 

        Dim Image As Bitmap = New Bitmap(600, 400)
        Dim g As Graphics = Graphics.FromImage(Image)
        g.DrawString(imgText, font, New SolidBrush(Color.Black), left, top)
        g.Flush()
        Response.ContentType = "image/jpg"
        Image.Save(Response.OutputStream, ImageFormat.Jpeg)
        Response.End()

Thank you in advance
