The Java sample provided in this section uses the Muhimbi PDF Converter Services Online to recognise text in image based files (scans, faxes, etc) using Optical Character Recognition (OCR). The OCRed content is returned in a PDF file with selectable and fully searchable text.
Additional sample code to convert, merge, watermark, secure and OCR files can be found here.
Full details about the ocr_pdf method, fields and properties can be found in the Wiki.
