%% ------------------------------------------
%%
%% Read me:
%% - Load your PDF (Project --> files)
%% - Change opportunely the size and the number of pages
%% - To discovering the correct size, you can use software like:
%% Inkscape, Gimp or a PDF Reader
%% - I put the units in mm but you can choose in whatever you want
%% - Activate a step at a time

%% Every time one of the following must be activated and the others deactivated
%% \includecomment{...} --> means turn ON
%% \excludecomment{...} --> means turn OFF
\includecomment{first} % for discovering the dimension of the cuts
\excludecomment{second} % for printing a cleaned and trimmed PDF
\excludecomment{third} % for joining the pages of the II stage without white spaces
% (save and use the new PDF before to do it)
%%
%% Define the file name and the dimension of your PDF
%% Put the size in mm
%% The typical size of an A4 document is 210x297 mm
\newcommand\units{mm} % <--- set the units (default mm)
\newcommand\fileName{two_side.pdf} % <--- the name of the PDF to process
\newcommand\width{420} % <--- the width size in mm of your PDF
\newcommand\height{297} % <--- the height size in mm of your PDF
%%
%% Do you want to crop the white spaces around the PDF?
%%
\newcommand\crop{1} % <-- "0" FALSE "1" TRUE
% If true put the dimension of the virtual rectangle that covers the pages
\newcommand\cutterW{150} % <--- the width size in mm of your cutter
\newcommand\cutterH{280} % <--- the height size in mm of your cutter
%%
%% Do you want to cut two sections per page?
%%
\newcommand\double{1} % <--- "0" FALSE "1" TRUE
%% If true put x_i, y_i the coordinates for moving the virtual rectangle in the page
%% the system start at the bottom left of the whole page
%% YOU CAN PUT ONLY INTEGER NUMBER
%% first rectangle in page (generally odd) or the only one
\newcommand\xOdd{30} % <-- x_1
\newcommand\yOdd{3} % <-- y_1
%% second rectangle in page (generally even)
\newcommand\xEven{242} % <-- x_2
\newcommand\yEven{3} % <-- x_2
%%
%% How many pages do you want to process?
%% default pages + 1, pages +0 if there are two page increment in the 2 step
\newcommand\numberPages{6} % <--- the numbers of pages
\newcommand\firstPage{1} % <--- fix the first page to start
