Class OcrResult.Page
Represents a single page within an OcrResult object.

Inherited Members
Namespace: IronOcr
Assembly: IronOcr.dll
Syntax
public class Page : OcrResult.OcrResultTextElementEverything OCR recognized on a single scanned or rendered page, structured for reading, lives on OcrResult.Page. One page object groups its text into words, lines, paragraphs, and blocks, surfaces any tables and barcodes found, and reports the page geometry, so you can extract plain text or navigate the layout from one place.
You get pages from a finished read: OcrResult.Pages returns an OcrResultPagesCollection, and each entry is a Page. A multi-page TIFF or PDF produces one Page per source page, ordered by PageNumber (1 based), which is why iterating result.Pages is the normal way to process a document. Each page derives from OcrResult.OcrResultTextElement, so it also carries the shared text, confidence, and bounding members.
The members fall into clear groups. The text-hierarchy properties are Words, Lines, Paragraphs, Blocks, and Characters, each an array in reading order from coarse to fine; WordCount gives a quick total. The structured-content properties are Tables, an array of OcrResult.Table detected on the page, and Barcodes, populated only when barcode reading is enabled on the input. The geometry properties are Width, Height, Rotation (degrees the original was turned to produce this result), and ContentArea, the Rectangle region OCR was applied to. ObjectModel exposes the page as an IOcrPageObjectModel, and ContentAreaToBitmap returns an AnyBitmap crop of the content area for a given OcrInput. Pick the level you need rather than reading every array.
using IronOcr;
var ocr = new IronTesseract();
using var input = new OcrInput();
input.LoadPdf("invoice.pdf");
OcrResult result = ocr.Read(input);
foreach (OcrResult.Page page in result.Pages)
Console.WriteLine($"Page {page.PageNumber}: {page.WordCount} words, {page.Tables.Length} tables");The OCR results objects example walks the page tree, the read PDFs how-to produces a page per PDF page, and the read tables how-to works through the Tables array.
