noweb.⚠️ Attention conservation notice: This is a fix for a very niche problem. Unless your printer is eating certain character from your print job, you had best move on. The punchline is: flatten the PDF.
Recently, I wanted to read a scanned PDF on my Kobo. The white-on-black PDF was quite “bright” for my tastes as I usually read at night. The Kobo supports dark mode for epubs but it doesn’t seem to have a means of inverting the colour of PDFs natively. Moreover, I like to read things as amber-on-black. A bit of vibe-coding and fiddling around yielded the following terrible script to make a PDF “amber on black.”
Thanks for reading! If you have any comments or questions about the content, please let me know. Anyone can contact me by email.
