scan2text

Shiny application to easily extract text from areas in images or scanned pdf files

Installation

Install the following R packages

install.packages("shinydashboard")
install.packages("shiny")
install.packages("shinyFiles")
install.packages("data.table")
install.packages("jsonlite")
install.packages("magick")
install.packages("pdftools")
install.packages("tesseract")

This uses R package pdftools to convert pdf files into png files.

• On Mac OS this requires you to install Ghostscript (e.g. as indicated at http://macappstore.org/ghostscript using Homebrew).
• On Linux this probably means installing Poppler as indicated at https://CRAN.R-project.org/package=pdftools
• On Windows you are probably safe as is
