Class OCR

java.lang.Object
  multivalent.std.adaptor.pdf.OCR

public class OCR

extends java.lang.Object

Normalize OCR + text, which can be implemented in various ways, into a document tree with hybrid image-text leaves (FixedLeafOCRs). Various ways to implement OCR + text in PDF:

1. image: full page, over content only (not margins), patches, strips width of screen but only 100 pixels high so you need 30 separate FAX images per page
2. text: invisible text (Tr 3), white text on white background
3. image + text: image over text, image under text, image under recognized text that's removed from background image (as in maps)
4. explicit background, which would erase background images drawn in Xdoc strategy
5. small bounding boxes from Capture, resulting in clipped endpoints

If determined to be scanned paper chunk, convert to method used in Xdoc.
