There are several ways to access the data in a RasterImage. If you need to get the RGB values of each pixel, then the GetPixel() and GetRow() methods are the simplest methods to use.

If you need to get just one pixel, then GetPixel() is the easiest.

The LEADTOOLS Document Analyzer is an innovative new library that intelligently finds and acts upon information in unstructured documents and images. The Document Analyzer handles what was once mundane and tedious manual work as it automatically sifts through data to find information of interest. Once a piece of information is found, an action such as highlight, redact, or extract can be applied. You will see below that the use cases of the Document Analyzer are widespread and varied, but all save time, reduce error, and improve the customer’s experience.
