scaling pdf's
=============

can use:

--

cpdf

cpdf -scale-to-fit "11.0in 17.0in" ./OTWS-ES-Junior-Progress-Awards-Player-Progress-A3-Chart.pdf -o cpdf_ledger.pdf

--

pdfjam

pdfjam --outfile jam_ledger.pdf --papersize '{11in,17cm}' ./OTWS-ES-Junior-Progress-Awards-Player-Progress-A3-Chart.pdf

--

but neither give good results.

Just import pdf into gimp and re-size/scale...

----

A4 -> letter

A3 -> ledger
