Resizing a selected area in a PDF in OS X

I am looking for a program that can resize a selected area in a PDF.

E.g. on Microsoft Windows with Microsoft Paint I can use the "Resize" feature:

(but Microsoft Paint doesn't support PDF and is not vectorial).

I would prefer if the program works with Mac OS X 10.10.

Attempts:

• Inkscape can resize a selected area in a PDF but it loses the page structure.


• GIMP is a raster graphics editor application (i.e. not vectorial): I want to keep it vectorial.


• I couldn't find a way to do it in Adobe Acrobat XI Pro.
