Or if PDF is PDF image with text layer in the background.
We can easily produce such text layer in PDF image by quickly OCR-ing it as "exact image" (20-30 min. for an average book) in Adobe Acrobat, Abbyy Finereader etc. because there is usually no need for detailed OCR behind "exact image" that will just double the needed time.
