### PDFINVERTER - darken (or lighten) a PDF

PDFInverter (GUI and CLI) will create a new PDF at the specified

location from a source PDF. All colors will be inverted (original shown on left):










Unfortunately page links are not preserved, but this program will darken PDFs making them suitable for night reading.

A 2-3 page PDF will invert very quickly. However a 400 page PDF may take 3-4 minutes.

This project should build on any platform with ImageMagick bindings for Golang. export CGO_CFLAGS_ALLOW='-Xpreprocessor' may need to be executed to run/build.

The GUI is developed with Golang QT bindings:



###### Get the project and build:


  

git clone https://github.com/rootVIII/pdfinverter.git

go build -o bin/pdfinverter

./bin/pdfinverter 

  



###### command-line usage:


  

# Required

-i     input PDF file path

-o     output PDF file path


Note:  If no command line arguments are provided, the GUI version will open.
