Currently, if you want to add images in a "Text Document" part, you can use the addImage function: https://developer.myscript.com/refguides/interactive-ink/android/1.3/com/myscript/iink/Editor.html#addImage-float-float-java.io.File-com.myscript.iink.MimeType-
If you want to import "Text", you can use the "addBlock" function, setting the proper "TEXT" MimeType: https://developer.myscript.com/refguides/interactive-ink/android/1.3/com/myscript/iink/Editor.html#addBlock-float-float-java.lang.String-com.myscript.iink.MimeType-java.lang.String-
Regarding "OCR", do you mean you would like to add images that contain text and get it recognized? Indeed, this cannot be done by our technology, which is not able to read text from images.
Thank you for the update.
But I am not sure to understand it. Is the above answer of help? What do you want to achieve?
