如何阅读PDF文件并将其显示在JTextPane上？

Question

I want to do a program that can choose a PDF file from my computer and later crop in few portions by automatically.

The concept I had first created a JfileChooser to select the file I want and display it on JTextPane , and then read / determine the structure of PDF file in order to crop in according to the portion I want.

Can I ask how to do it? Any library I can refer to?

Answer 1

You could use this PDFBox API to manipulate PDF file to your Java program. There is enough documentation there about text extraction for you to follow.
