[iText-questions] how can i simply check if a PDF contains Searchable Text?

[Aaron J Weber]

I need to workaround a known Acrobat Capture issue where it fails to OCR a PDF (even after it's converted to TIFF?) if the PDF already contains text (i.e. is not a PDF-Image-Only document).   Since I'm batch-processing, I don't have the luxury of opening each document and trying to select some text from Acrobat to test.  I need an automated method of pre-validating the PDF so it doesn't cause Capture to hang.   Thus my question: Does anyone have a snippet that "peeks" at a PDF's contents and checks to see if it's PDF+Text (of some kind)?  Since I don't have a standard "search string" to check for, I guess I'd be content just checking if ANY text is readable/exists in the PDF or if the PDF is "Image Only".   Thanks in advance, AJ
