Nach dem Release von webPDF 8.0 im November letzten Jahres, steht jetzt das erste Update zur Verfügung. Mit der Revisionsnummer 2058 steht ab sofort im Download die neue Version zur Verfügung, die neben Bugfixes auch ein einige neue Funktionen bringt:
This example explains how to use the OCR webservice of webPDF. OCR in webPDF is based on Tesseract. By default, German, English, French, Spanish, and Italian are supported. Additional languages can be installed in the Tesseract folder (see the webPDF manual for details).
Languages using a multibyte character set are currently not supported, for example Arabic and several Far Eastern languages. OCR is mainly useful for documents that contain text visually, but not as embedded searchable text. For extracting already embedded text from PDF documents, webPDF provides an option in the Toolbox webservice.
