Syntax
public sealed class ResultHighlightType : Enum

Choosing how IronOCR draws debug highlights runs through ResultHighlightType, passed to HighlightTextAndSaveAsImages when an input is saved as annotated images. Word boxes each recognized word and is the usual choice for spot-checking accuracy, Character highlights individual glyphs for the finest-grained view, Line groups by text line, and Paragraph outlines whole blocks for a layout-level check. The highlight text how-to writes annotated images for debugging.
