In PSPDFKit how do I get highlighted text?

There is an older response to this question in How can I get the highlighted text from PSPDFKit? but all the links are dead and the solution may have been refactored drastically since 2014.

All I get from the response from instance.exportInstantJSON() is the coordinates of a rectange annotation of my highlighted annotation, is there any way to resolve these coordinates and get the text being highlighted?

Solution

  • I dug a bit deeper in the API documentation and found there is a instance.getMarkupAnnotationText method which does the job.

    const annotations = await instance.getAnnotations(0);
const markupAnnotations = annotations.filter(
  annotation => annotation instanceof PSPDFKit.Annotations.MarkupAnnotation
);
const text = await Promise.all(
  markupAnnotations.map(instance.getMarkupAnnotationText)
);
console.log(text);
