IronOCR 也支援 Stream。
在這個範例中，IronPDF 被用於建立 PDF Stream，之後可以由 IronOCR 用於文字識別。
請注意，IronOCR 只能將 Stream 作為輸入，但不支援將 Stream 輸出為檔案。
using IronOcr;
using IronPdf;
using System;
ChromePdfRenderer renderer = new ChromePdfRenderer();
PdfDocument pdf = renderer.RenderHtmlAsPdf("<h1> Iron Software </h1>");
var ocrTesseract = new IronTesseract();
using var ocrInput = new OcrInput();
ocrInput.LoadPdf(pdf.Stream);
var ocrResult = ocrTesseract.Read(ocrInput);
Console.WriteLine(ocrResult.Text);
