SearchWP Xpdf Integration
This Extension needs exec() and requires you to install Xpdf command line tools on your own.
SearchWP provides the distinct feature of removing plain text from PDF data uploaded to your WordPress website. Out of the package, SearchWP efforts to do this using just PHP, yet as a result of the intricacy as well as variation of the PDF layout, that sometimes leads to material not being correctly drawn out. Enter Xpdf.
Using the Xpdf Integration Extension, you can unload all the work PHP has to perform in processing your PDF files to Xpdf’s command line devices, which are very fast and exact when extracting content from your PDFs. After turning on the Extension, you must adhere to the setup instructions. Once installed, SearchWP will unload the PDF web content removal process to Xpdf.
