I have the position of a stream of characters in the input pdf file. Each character has a TextPosition object.
Suppose that, I want to highlight this stream of characters. As I know, I have to leverage PDAnnotationTextMarkup. This class requires the position of the annotation which is set by "setRectangle()" and "setQuadPoints()" functions. I don't know how to convert a TextPosition object into PDRectangle and QuadPoints equivalence.
