This demo shows you how to use our
OCR Engines to parse a non-searchable or searchable document. It displays each character in a listbox and highlights the character in the image when selected. The exact bounds of the character are also displayed in a text box just below the list box.
The demo also shows you how to obtain the recognized words from the document. The words are also displayed in a list box and also highlighted when selected with their coordinates displayed in the same text box as the characters.
To perform the same task with a searchable PDF with no OCR engine, please follow this
link to find the same demo using our
PDFDocument class. The PDFDocument class will be able to extract the text as well as other PDF objects without using an OCR engine.
This C# project was created with Visual Studio 2008.
