Configuration

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.

On native platforms, you can access the Configuration via your Engine object. Refer to the Interactive Ink runtime page of the guide for more instructions.

Further options are available to customize your styling with css properties. They are inventoried in the styling page.

In the tables below, note how the ${KEY_NAME} syntax allows retrieving the value of another key.
