(1) Read text data

There is no special need to explain the text, that is, to get the start page and end page of the PDF text, and get all the text of the PDF directly through the getText function.

(2) Get the middle picture of the PDF

Save the captured image object in PDF to another PDF

This method can take out the image object PDImageXObject in the source PDF, and then can perform related processing on the object. This code realizes inserting each extracted image object into a blank PDF document.
