Tool to crop the figure in a pdf page generated by a powerpoint (or equivalent) tool.
Usage is simple, export pptx to pdf, then:
bash figures_process.sh FILE PAGEID FIG_NAME PAGEID2 FIG_NAME ... Where FILE is the pdf file name (without the extention .pdf!), and PAGEID* are the page numbers where you want to crop a figure, and FIG_NAME* the associated name to give to the figure.
This tool is a slightly modified version initialized coded by Thomas Robert.
