// Instantiate OCR engine
var ocr = new IronTesseract();

// Configure OCR engine
using var input = new OcrInput();
input.LoadImage("potter.tiff");

// Perform OCR
OcrResult result = ocr.ReadDocument(input);
Console.WriteLine(result.Text);

// Perform OCR
OcrResult result = ocr.ReadDocument(input);
Console.WriteLine(result.Text);

Imports IronOcr
Imports System

' Instantiate OCR engine
Dim ocr As New IronTesseract()

' Configure OCR engine
Using input As New OcrInput()

阅读发票文件

从发票中智能提取结构化数据，实现应付账款工作流程自动化。除了简单的文本提取外，还能捕捉发票号码、到期日、总金额和供应商名称等键值对，甚至可以跨不同的布局和模板。

了解如何：阅读文档中的复杂表格

using IronOcr;

// Instantiate OCR engine
var ocr = new IronTesseract();

// Enable table detection
ocr.Configuration.ReadDataTables = true;
using var input = new OcrPdfInput("sample.pdf");
var result = ocr.Read(input);

// Retrieve the data
var table = result.Tables[0].DataTable;

// Print the retrieved item to the console
Console.WriteLine($"The first item in the table is: {result.Tables[0].DataTable.Rows[0][0]}");

using IronOcr;

// Instantiate OCR engine
var ocr = new IronTesseract();

// Enable table detection
ocr.Configuration.ReadDataTables = true;
using var input = new OcrPdfInput("sample.pdf");
var result = ocr.Read(input);

// Retrieve the data
var table = result.Tables[0].DataTable;

// Print the retrieved item to the console
Console.WriteLine($"The first item in the table is: {result.Tables[0].DataTable.Rows[0][0]}");

Imports IronOcr

' Instantiate OCR engine
Dim ocr As New IronTesseract()

' Enable table detection
ocr.Configuration.ReadDataTables = True
Using input As New OcrPdfInput("sample.pdf")
    Dim result = ocr.Read(input)

    ' Retrieve the data
    Dim table = result.Tables(0).DataTable

    ' Print the retrieved item to the console
    Console.WriteLine($"The first item in the table is: {result.Tables(0).DataTable.Rows(0)(0)}")

读取照片

将智能手机照片和相机图像转化为可用文本。适用于捕捉收据用于费用跟踪、将白板笔记数字化、从产品标签中提取信息或从路标和海报中读取文本的移动应用程序。

了解如何：在 C# 中使用读取照片

using IronOcr;

var ocr = new IronTesseract();
using var inputPhoto = new OcrInput();
inputPhoto.LoadImageFrame("ocr.tiff", 0);

// Read photo
OcrPhotoResult result = ocr.ReadPhoto(inputPhoto);

// Extract the text in the first region
string textinregion = result.TextRegions[0].TextInRegion;

// Print the text in the first region 
Console.WriteLine($"Full Scnned Photo Text: {textinregion}");

using IronOcr;

var ocr = new IronTesseract();
using var inputPhoto = new OcrInput();
inputPhoto.LoadImageFrame("ocr.tiff", 0);

// Read photo
OcrPhotoResult result = ocr.ReadPhoto(inputPhoto);

// Extract the text in the first region
string textinregion = result.TextRegions[0].TextInRegion;

// Print the text in the first region 
Console.WriteLine($"Full Scnned Photo Text: {textinregion}");

Imports IronOcr

Dim ocr = New IronTesseract()
Using inputPhoto = New OcrInput()
    inputPhoto.LoadImageFrame("ocr.tiff", 0)

    ' Read photo
    Dim result As OcrPhotoResult = ocr.ReadPhoto(inputPhoto)

    ' Extract the text in the first region
    Dim textinregion As String = result.TextRegions(0).TextInRegion

    ' Print the text in the first region 
    Console.WriteLine($"Full Scnned Photo Text: {textinregion}")
End Using
