app to pass files in directory to external processor

I require an application that will scan a set of directories and subdirectories for PDF files and create text-searchable versions. The application to create text-searchable PDFs will be purchased, the application need only manage the directory crawling. The application will also have a "watched folder" feature where if a file is placed in a folder it will be ocr'ed into another folder. This application should run as a service (and have accompanying applet with configuration and log file viewer for real-time watch of scanning process) The application being used for OCR is img2pdf command line version. There is a downloadable demo available. ## Deliverables Process detail: 1. Folder (and subfolders)? is scanned at predefinted time, or triggered via the applet. 2. A PDF is found and it's "creator" property is evaluated. If it is "img2pdf" then it has already been recognized and is bypassed 3. If the pdf creator property is not img2pdf a command line application is called to create a new pdf that has been ocr'd by the external command line app. 4. If process is successful, the old pdf is either renamed with a .old extension or deleted (based on configuration variable) and the new file renamed as the original file name. 5. If config varible is set to log, a log file is appended to with filename, OCR process time (if processed). If not processed and just skipped over log as well. Errors should be captured and logged. Watched folder process detail: 1. System scans input folder every x mins (defined in config), or triggered manually via applet 2. Looks for files with thexe extensions:? TIFF,JPG,PNG,GIF,PCD,PSD,TGA,BMP,DCX,PIC,TIF 3. Runs each file through img2pdf 4. If process is successful, the old pdf is either renamed with a .old extension or deleted (based on configuration variable) and the new file renamed as the original file name. 5. If config varible is set to log, a log file is appended to with filename, OCR process time (if processed). If not processed and just skipped over log as well. Errors should be captured and logged. Configuration variables 1. img2pdf location 2. img2pdf command line variables. This only needs to be any additional options as part of command line 3. Daily times for folder scanning (allow multiple) 4. Folders for folder scanning (drive letters accepted, multiple folders) 5. Original pdfs saved (true/false) 6. Debug log (true/false) 7. Watched folder check time (every x mins) 8. Watched folder input file 9. Watched folder output file Command line information for img2pdf Image2PDF v3.5: Convert and combine images into a PDF file.
