I want to write a program that search .pdf files in specific directory
and run OCR for all files.

Is there a way to create program that
1. Capture image from pdf
2. Select small section from that image and capture character.

I was able to do OCR from Adobe Acrobat 7 Professional, but it was
manual work.
and PDF Viewer doesn't support that method.

if anyone knows, please let me know~
