Configuration

Interactive Ink 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 sent in the request body with each call the REST endpoint. Refer to the user guide for more instructions.

Cloud Development Kit (API V3) parameters

The following parameters are only applicable if you use the legacy api V3. This API will be deprecated as soon as all the important features are available in iink SDK.

When using MyScriptJS or web-components the prefix recognitionParams.V3. should be added.

Math

Key	Type	Default value	Description
`mathParameter.resultTypes`	array of string	`['LATEX', 'MATHML']`	Export types, `LATEX` is mandatory if export zone is active
`mathParameter.columnarOperation`	boolean	`false`	True to activate columnar recognition
`mathParameter.userResources`	array of string	`[]`	Custom user resources to use
`mathParameter.scratchOutDetectionSensitivity`	number	1	Sensitivity of to scratch-out gesture

Text

Key	Type	Default value	Description
`textParameter.language`	string	`en_US`	Language to be used
`textParameter.textInputMode`	string	`CURSIVE`	`ISOLATED`, `CURSIVE`, `VERTICAL`, `SUPERIMPOSED`* This describes the type of writing - isolated (for example in boxed fields) and cursive (any other type of natural writing). Only available in Japanese. *60 supported languages.
`textParameter.resultDetail`	string	`TEXT`	`TEXT`, `WORD`, `CHARACTER` This describes the level of result detail you want. If you ask for `TEXT` level, you only get the final result for the whole ink sample. Results can also be broken down into `WORD` or `CHARACTER` level, if you want to offer alternative recognition candidates.
`textParameter.contentTypes`	array of string	`[]`	The content type describes the expected linguistic type of input. The default is text which means that the recognizer will use a broad lexicon of general text. You can specify others for different types of fields such as surnames, city names, numbers, etc. You can specify more than one.
`textParameter.subsetKnowledges`	array of string	`[]`	Subset knowledge is a way of telling the recognizer that you only want it to enable only certain characters. For example, for a phone number field, you may want only digits to be recognized. They are language-specific but generally offer digits, punctuation, alphabetical and alphanumerical characters and upper/lower case letters.
