how to check the pdf is in maximum size or not

I need to know the whether current pdf is in maximum size or not?.I tried with extending the PDFReader class.But i am unable to get the m_view value to extending class as its private variable.Is there any other way to get this ?

You can simply change it to protected

I can change the library Radaee.But it is not good practise i think as if we plane to add new version of library we have to do all changes in new library.So i thought to overrides the function of existing in library is better way.Also if we change the library does it affect to license?

Changing the java code has no effect on the license, what you are saying is true...but for what you are asking, currently this is the only way.

Nermeen is right, change it to protected, this is the only option.
