Where does IResultRenderer live in the IronOCR API?

IResultRenderer is an interface in the DynamicTesseract namespace, shipped in IronOcr.dll. It extends IDisposable and defines BeginDocument, AddPage, and PageNumber for writing recognized pages to an output document.

How do you write OCR results to a document with IResultRenderer in C#?

Call BeginDocument with a title to open the output and capture the returned IDisposable in a using block, call AddPage for each recognized Page, and read PageNumber for the running count. Disposing the document handle finishes the file.

Interface IResultRenderer

Namespace: DynamicTesseract

Assembly: IronOcr.dll

Syntax

public interface IResultRenderer

IResultRenderer is the contract for writing recognized Page results into an output document, such as a searchable PDF, hOCR file, or plain text export. A renderer accumulates pages and tracks how many it has written, so the same recognition pass can feed one multi-page document.

Three members define the contract. BeginDocument opens a new output document under a given title and returns an IDisposable that closes the document when disposed, so a using block frames the whole write. AddPage writes one recognized Page into the open document and returns whether the page was accepted. PageNumber reports how many pages have been rendered so far. Because the contract extends IDisposable, dispose the renderer to release its native output handle once every page is written, and dispose the document handle that BeginDocument returns to finalize the file on disk.

The searchable PDF how-to and the hOCR export how-to cover the high-level output that this rendering layer backs.
