for 2 days now I'm trying to resize my Canas data to get a smaller value when calling Canvas.toDataUrl.
User draws to a Canvas (Sign something). The drawing Canvas is sized to the Window size.
Before transgering the data to the server I want to scale the Canvas to fit to a smaller size.
I think this is very simple, but at the moment I'm bainfucked :-).
- Get Canvas data
- Resize/Scale Canvas data
- Get data by calling Canvas.toDataUrl
- Transfer to server as image/png;base64..... String
Thanks a lot for any answer.
