PDF analysis using PDF box

[Subhajit Das]

Hi There,

I am new in PDF box. I need to know PDF content type, like how much text, how 
many embedded images, size of them etc.
How do I accomplish that?
I found : 
https://svn.apache.org/viewvc/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/pdmodel/ExtractEmbeddedFiles.java?view=markup
But this is general for all embedded files. How can I make specific for 
embedded images?
Thanks and Regards,
