💖 HOCR2PDF — the ExactImage manual, bestie edition 💖

okay so you're holding the hocr2pdf(1) page, and I'm gonna walk you through it like we're texting at 2am. it's from the ExactImage Manual. buckle up 🎀

✨ NAME ✨

hocr2pdf — the hOCR-to-PDF converter from the ExactImage toolkit. it's giving "turn my scan into a real document" energy 💅

🌸 SYNOPSIS 🌸

hocr2pdf [option...] {-i | --input} input-file
         {-o | --output} output-file

hocr2pdf {-h | --help}

like, you need an input and an output, no cap. or you can just ask for help. 🤷‍♀️

🦋 DESCRIPTION 🦋

ExactImage is a fast C++ image processing library. and the way it's different from a lot of other library frameworks?? it lets you work in several color spaces and bit depths natively, which means low memory and computational requirements. lowkey iconic. 🔥

hocr2pdf creates well layouted, searchable PDF files from hOCR (annotated HTML) input that you got from an OCR system. so like, your OCR did the reading, and this one makes it pretty and searchable. periodt. 💖

👑 OPTIONS 👑

  • -i file, --input file — read the image from the file you name. careful bestie: the input hOCR is read from standard input, not from this file. two different inputs, iykyk 🙈
  • -o file, --output file — save the output PDF to this file.
  • -n, --no-image — don't place the image over the text. by default the text layer is hidden behind the image.
  • -s, --sloppy-text — sloppily place text, group words, and do not draw single glyphs. it's called sloppy on purpose, she's allowed to be messy 💅
  • -r n, --resolution n — override the resolution of the input image to n dpi. the default resolution (if it's not specified in the input file) is 300 dpi.
  • --quality — quality setting used for writing compressed images. integer range 0-100, the default is 75.
  • --compress — compression method for writing images, e.g. ascii85, hex, flate, jpeg, jpeg2000, ... default is based on bit-depth.
  • -h, --help — display help text and exit. bye bestie 🫶

🌈 EXAMPLE 🌈

$ hocr2pdf -i scan.tiff -o test.pdf < cuneiform-out.hocr

see how the hOCR comes in through < on stdin while the image comes from -i? chef's kiss 😭✨
