reading PDF and convert each single page to an image

I need to read a PDF and do the following:

- determine the number of pages.

- determine the chapters (Tree/Hierarchy of pages ).

- determine the height and width of the page.

- convert each single page to JPG image.

is there any clear and simple API that contains these functions

i tried PDFBox, but it seems it is not that easy.

any suggestions, i would be grateful.

Thanks
