Example Usage and Walkthrough

Set a Highlight Type

By default, no highlighting will be added on the View Panel. To enable this, select one of the settings from the Highlight Settings menu. The recommended one to use is Word: Highlight Menu Screen

This will highlight all words that IronOCR can see, and you may even hover over words to see the guessed word, and the confidence. The deepness of red highlighting is relative to how confident it is: Highlight Word Screen

Improve Read by Applying a Filter

Many images contain noise, blurriness, and crookedness. We must filter those out for a proper read. As see in the following image, the text is now straight and must be deskewed to icrease confidence and result quality: Skewed Image

Navigating to the left Filters Panel, we can queue many filters to see them update real-time, as well as dequeue or set their values: Filter Location

Applying a Deskew filter here will update the code in the Output panel on the right, as well as make the result much more accurate: Filter Deskew Applied

Export Results or Add to .NET Project

To get this result in your own project, the COPY button in the Code Panel allows you to export the code that reproduces exactly the same result as you got in the Output Panel. Simple paste the code into your IDE and replace the filepath to your image filepath. Save Code

Very useful for scanned documents, if you want a Searchable PDF that has text overlayed on the original image or PDF, you can export it with the EXPORT AS PDF button: Sace Searchable PDF
