MyScript iink SDK is a flexible toolkit, and its default configuration can be adjusted to meet different needs. This page lists available options, their default values and usage.

The configuration is to be sent with the configuration message.

General

For the sake of clarity, path of parameter are given. For example export.jiix.bounding-box key match following entry in the body :

"configuration": {
  "export": {
    "jiix": {
      "bounding-box": "..."
    }
  }
}

Content type compatibility

Interactive Ink using WebSocket protocol supports MATH and TEXT recognition in onscreen mode and RAW CONTENT in offscreen mode. See architecture for more details on both modes.
