Where does DictionaryInspector live in the IronOCR API?

DictionaryInspector is a class in the DynamicTesseract namespace, shipped in IronOcr.dll. It derives from Object and is constructed directly with its default constructor before its check methods are called.

How do you check a Tesseract trained-data file in C# with IronOCR?

Create a DictionaryInspector and call TrainedDataSupportsLtsm to test the LSTM neural path, or TrainedDataSupportsOem for the legacy engine path, passing the trained-data path and a TesseractVersion. Use it to validate a custom language pack before loading it.

DictionaryInspector

Namespace: DynamicTesseract

Assembly: IronOcr.dll

Syntax

public class DictionaryInspector : Object

DictionaryInspector is the helper that answers whether a Tesseract trained-data file works with a given engine mode before a read is attempted. A .traineddata language pack may carry an LSTM model, a legacy model, or both, and pairing the wrong pack with the wrong engine mode is a common cause of a failed or empty OCR run. This type lets interop code check that compatibility up front.

Construct one and call TrainedDataSupportsLtsm, passing the trained-data path and a TesseractVersion, to confirm the pack contains the LSTM model the modern neural engine needs. TrainedDataSupportsOem performs the matching check for the legacy Tesseract OEM path. Each returns a simple yes or no for that combination, which sits in the validation step that runs before a custom or downloaded language pack is loaded. It lives in the DynamicTesseract interop layer beneath IronOCR; most projects rely on IronOCR's bundled language packs and never need it, but code that ships its own trained data can use it to fail fast with a clear message.

The custom language how-to covers loading your own trained data, and the custom font training how-to walks through producing a pack.
