Where does FontInfo live in the IronOCR API?

FontInfo is a class in the DynamicTesseract namespace, shipped in IronOcr.dll. It derives from Object and is produced by the engine during recognition rather than constructed in everyday code.

What font details does FontInfo report in C#?

It reports the family Name and an Id, plus the style flags IsBold, IsItalic, IsSerif, IsFixedPitch, and IsFraktur, covering weight, slant, serif versus sans, monospacing, and blackletter Fraktur faces.

How does FontInfo relate to FontAttributes in IronOCR?

FontInfo describes a font family and its fixed traits; FontAttributes describes how that font was used at one position, holding a FontInfo along with the detected point size, small caps, and underline. Read FontInfo for the family and FontAttributes for the per-span styling.

Syntax

public class FontInfo : Object

FontInfo is the record of a single font that Tesseract identified while recognizing a page. It names the font family and the fixed typographic traits that family carries, so interop code that needs to know what a piece of text was set in, rather than merely what it said, reads its properties. The nearest type it is paired with is FontAttributes, which describes how a font was used at one position; FontInfo is the shared family description those per-span attributes point back to.

A FontInfo is produced by the engine during recognition, not constructed by hand, and turns up wherever the result surface exposes font detail. The everyday properties split into two groups. Identity is Name, the font family name as a String, and Id, an Int32 index the engine assigns to that font within a read. Style traits are the Boolean flags IsBold, IsItalic, IsSerif, IsFixedPitch, and IsFraktur, reporting weight, slant, whether the family is serif or sans, whether it is monospaced, and whether it is a blackletter Fraktur face. Reading those flags lets code rebuild approximate formatting, distinguish a heading font from body text, or flag unusual faces that may need a different language model.

Because the values come straight from the recognizer, treat them as the engine's best estimate rather than ground truth, and read them after a successful recognition pass. For ordinary text extraction the high-level IronOCR result objects are the simpler surface; reach for FontInfo through the DynamicTesseract layer when font-level detail is what the task needs.

Console.WriteLine($"{font.Name} bold={font.IsBold} serif={font.IsSerif}");

The read results how-to walks through the result model, and the result confidence how-to explains how reliable a recognition pass is before trusting its font detail.
