These commands will let you make a thumbnail quilt of all 448 pages of the Mueller Report PDF.
Make a new directory...
mkdir mueller_quilt
...then cd into it.
cd mueller_quilt
Grab a copy of the report:
wget https://www.justice.gov/storage/report.pdf
First install Imagamegick and ghostscript (asuming you are on Mac, and you have Homebrew)
brew install imagemagick
brew install ghostscript
This will split the PDF into 448 individiual PNG files, and scale them to 25% of their original size.
convert -density 72 report.pdf -resize 25% report.png
This will then assemble those PNGs into a quilt 20 pages across
montage null: *.png null: -geometry +0+0 -tile 20x -gravity center report_quilt.png
That's it!
Ah yes...forgot about that. Will edit this. Thanks!
