📦 version 0.7.0, in nixos 26.05, nixpkgs unstable

🎀 NAME 🎀

bestie, this is the man(1) page for jfbview — aka the jfbview man page — and it's literally a PDF and image viewer for the Linux framebuffer. iconic behavior, no cap. 💅

🌸 SYNOPSIS 🌸

jfbview [OPTIONS] FILE

✨ DESCRIPTION ✨

okay so jfbview is a PDF and image viewer for the Linux framebuffer. that's the whole vibe. 🦋

💖 OPTIONS 💖

  • --help, -h — shows the help message. cute, helpful, slay. ✨
  • --fb=/path/to/dev — specifies the path to the output framebuffer device. the default is /dev/fb0. 🎀
  • --password=xxx, -P xxx — unlock the PDF document with the given password. 🔐
  • --page=n, -p n — go to page n on start up. 📄
  • --zoom=n, -z n — set initial zoom to n percent. for example, -z 75 sets zoom to 75%. 🔍
  • --zoom_to_fit — start in zoom-to-fit mode. 🫶
  • --zoom_to_width — start in zoom-to-width mode. this is the default. 👑
  • --rotation=n, -r n — set initial rotation to n degrees clockwise. 🔄
  • --color_mode=invert, -c invert — start in inverted color mode. 🌈
  • --color_mode=sepia, -c sepia — start in sepia color mode. 🍓
  • --cache_size=n — selects the number of pages to cache. jfbview has an in-memory cache of pages rendered at a particular zoom and rotation setting. however, you may wish to adjust the cache size down if this cache is consuming too much memory, or you may wish to adjust the cache size up for increased performance. if you have an older machine with limited RAM you may want to set it close to zero. 🧚
