This demo shows you how to use our PDFDocument class to parse a searchable PDF document; extracting the text. 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 convert the characters into words. 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.

This demo will only work with PDF's that are searchable and requires no OCR engine.

To perform the same task with a non-searchable PDF you will need an OCR engine. Please follow this link to find this same demo using an OCR engine instead to parse the PDF. The OCR engine will be able to parse other non-searchable formats as well (such as TIFF, JPEG, PNG, GIF, etc.)

This C# project was created with Visual Studio 2008.
