IronOCR也支持Stream。
在此示例中，IronPDF用于创建一个PDF Stream，日后可以通过IronOCR进行文本识别。
请注意，IronOCR只能将Stream作为输出文件导出。
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);
Imports IronOcr
Imports IronPdf
Imports System
Dim renderer As New ChromePdfRenderer()
Dim pdf As PdfDocument = renderer.RenderHtmlAsPdf("<h1> Iron Software </h1>")
Dim ocrTesseract As New IronTesseract()
Using ocrInput As New OcrInput()
ocrInput.LoadPdf(pdf.Stream)
Dim ocrResult = ocrTesseract.Read(ocrInput)
Console.WriteLine(ocrResult.Text)
End Using
