Beginner's set up for AidenLX’s Zotero Integration Plugin

The current official documentation is incomplete, and inaccessible for most users, however I believe it is the best zotero integration so far, if only it can eventually match the features of Bibnotes Formatter. I want to make a simple guide for users who want to quickly set up the plugin with simple use cases.

Simulate a scanned PDF with ImageMagick

1. Download and install Ghostscript and ImageMagick + Convert Module
2. Execute the following command in the console (change the filename)

$ convert -density 200 INPUT.pdf -rotate 0.3 +noise Multiplicative -format pdf  -quality 85 -compress JPEG -colorspace gray OUTPUT.pdf

Description of the options

• -density: set the input DPI to 200
• -rotate: set Page rotation to 0.3 degrees

fieri

# use ImageMagick convert
# the order is important. the density argument applies to input.pdf and resize and rotate to output.pdf
convert -density 90 input.pdf -rotate 0.5 -attenuate 0.2 +noise Multiplicative -colorspace Gray output.pdf
