Crop pdf: PDF Arranger is a small

PDF Arranger is a small python-gtk application, which helps the user to merge or split pdf documents and rotate, crop and rearrange their pages using an interactive and intuitive graphical interface. I am looking for an open source command line tool to crop PDF file just like we can do in Adobe Acrobat Pro. I have tried PdfTk, ImageMagick, PyPDF, and GhostScript—all with no success so far. CUPS- PDF (as virtual printer) But I could not find any settings in okular and qpdfview to crop or resize the pdf pages by their trimbox values. I have printed my pdf file whose pages have trimbox values (with my way or ready pdf file that I know trimbox values properly added to the pages) as again pdf file in Boomaga and CUPS- PDF . 2 I saw this Command line tool to crop PDF files. Being ignorant couldn't understand it. How can I crop all the pages with same dimension (except last and front)? This is precisely the book. Also how to select the dimensions properly? That will be helpful.
