Hello,

Thank you for contacting us.

With Offscreen interactivity, your application is responsible for the ink capture and rendering, so you cannot use iink SDK  to generate the strokes of the solver output (the strokes corresponding to the 4 digit in your example).

Nevertheless, you can get the solver result by using a MathSolverController.

For instance, the code snippet below, that you can insert in the contentChanged, of your IOffscreenEditorListenerimplementaion,  allows you to retrieve the math solver numerical computation output:

                blockIds.forEach { blockId ->
                    val itemIdHelper = itemIdHelper ?: return@forEach
                    val offscreenEditor = offscreenEditor ?: return@forEach

                    if (itemIdHelper.getBlockType(blockId) == "Math") {
                        offscreenEditor.mathSolverController.getAvailableActions(blockId)?.let { actions ->

                            if (actions.contains("numerical-computation")) {
                                val latexExport = offscreenEditor.mathSolverController.getActionOutput(
                                    blockId,
                                    "numerical-computation",
                                   MimeType.LATEX
                              )
                               Log.d(TAG, "Latex: $latexExport")
                            }
                       }
                    }
               }

Please note, that you can get the actionOutput either as LaTeX (as in above snippet) or JIIX.

With the ink example you have shared, you would get the LaTeX output "1+3=4" that you can  then use in your application.

Best regards,
