額外的 OCR 語言包

Translated

View the article in English

IronOCR 支援 125 種國際語言，但系統中預設僅安裝英語。

可透過 NuGet 或下載 Dll 並添加為專案引用，輕鬆將額外的語言包添加到您的 C#、VB 或 ASP .NET 專案中。

程式碼範例

國際語言範例

//PM> Install-Package IronOcr.Languages.ChineseSimplified

using IronOcr;

IronTesseract ocr = new IronTesseract();
ocr.Language = OcrLanguage.ChineseSimplified;

using (var input = new OcrInput())
{
    input.AddImage("img/chinese.gif");

    // Add image filters if needed
    // Input.Deskew();
    // Input.DeNoise();

    OcrResult result = ocr.Read(input);

    string TestResult = result.Text;

    // Console can't print unicode. Save to disk instead.
    result.SaveAsTextFile("chinese.txt");
}

//PM> Install-Package IronOcr.Languages.ChineseSimplified

using IronOcr;

IronTesseract ocr = new IronTesseract();
ocr.Language = OcrLanguage.ChineseSimplified;

using (var input = new OcrInput())
{
    input.AddImage("img/chinese.gif");

    // Add image filters if needed
    // Input.Deskew();
    // Input.DeNoise();

    OcrResult result = ocr.Read(input);

    string TestResult = result.Text;

    // Console can't print unicode. Save to disk instead.
    result.SaveAsTextFile("chinese.txt");
}

'PM> Install-Package IronOcr.Languages.ChineseSimplified

Imports IronOcr

Private ocr As New IronTesseract()
ocr.Language = OcrLanguage.ChineseSimplified

Using input = New OcrInput()
	input.AddImage("img/chinese.gif")

	' Add image filters if needed
	' Input.Deskew();
	' Input.DeNoise();

	Dim result As OcrResult = ocr.Read(input)

	Dim TestResult As String = result.Text

	' Console can't print unicode. Save to disk instead.
	result.SaveAsTextFile("chinese.txt")
End Using

垂直書寫語言範例

針對直書式語言調整的字典。使用韓國和日本的OcrLanguage的'垂直'變體。

using IronOcr;

IronTesseract ocr = new IronTesseract();
ocr.Language = OcrLanguage.JapaneseVertical;

using (var input = new OcrInput(@"images\image.png"))
{
    OcrResult result = ocr.Read(input);
    Console.WriteLine(result.Text);
}

using IronOcr;

IronTesseract ocr = new IronTesseract();
ocr.Language = OcrLanguage.JapaneseVertical;

using (var input = new OcrInput(@"images\image.png"))
{
    OcrResult result = ocr.Read(input);
    Console.WriteLine(result.Text);
}

Imports IronOcr

Private ocr As New IronTesseract()
ocr.Language = OcrLanguage.JapaneseVertical

Using input = New OcrInput("images\image.png")
	Dim result As OcrResult = ocr.Read(input)
	Console.WriteLine(result.Text)
End Using

自訂語言範例

若您已下載或自行訓練任何 Tesseract .Traineddata 語言檔案，使用方法如下

using IronOcr;

IronTesseract ocr = new IronTesseract();

ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");

using (var input = new OcrInput(@"images\image.png"))
{
    OcrResult result = ocr.Read(input);
    Console.WriteLine(result.Text);
}

using IronOcr;

IronTesseract ocr = new IronTesseract();

ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");

using (var input = new OcrInput(@"images\image.png"))
{
    OcrResult result = ocr.Read(input);
    Console.WriteLine(result.Text);
}

Imports IronOcr

Private ocr As New IronTesseract()

ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata")

Using input = New OcrInput("images\image.png")
	Dim result As OcrResult = ocr.Read(input)
	Console.WriteLine(result.Text)
End Using

多語言示例

一次使用多種語言。

//PM> Install-Package IronOcr.Languages.Arabic
using IronOcr;

IronTesseract ocr = new IronTesseract();

ocr.Language = OcrLanguage.English;
ocr.AddSecondaryLanguage(OcrLanguage.Arabic);
// Add any number of languages

using (var input = new OcrInput(@"images\multi-lang.pdf"))
{
    var Result = ocr.Read(input);
    Console.WriteLine(Result.Text);
}

//PM> Install-Package IronOcr.Languages.Arabic
using IronOcr;

IronTesseract ocr = new IronTesseract();

ocr.Language = OcrLanguage.English;
ocr.AddSecondaryLanguage(OcrLanguage.Arabic);
// Add any number of languages

using (var input = new OcrInput(@"images\multi-lang.pdf"))
{
    var Result = ocr.Read(input);
    Console.WriteLine(Result.Text);
}

'PM> Install-Package IronOcr.Languages.Arabic
Imports IronOcr

Private ocr As New IronTesseract()

ocr.Language = OcrLanguage.English
ocr.AddSecondaryLanguage(OcrLanguage.Arabic)
' Add any number of languages

Using input = New OcrInput("images\multi-lang.pdf")
	Dim Result = ocr.Read(input)
	Console.WriteLine(Result.Text)
End Using

更快的語言範例

字典調整為快速。使用任何 OcrLanguage 的「Fast」變體。

using IronOcr;

IronTesseract ocr = new IronTesseract();
ocr.Language = OcrLanguage.EnglishFast;

using (var input = new OcrInput(@"images\image.png"))
{
    OcrResult result = ocr.Read(input);
    Console.WriteLine(result.Text);
}

using IronOcr;

IronTesseract ocr = new IronTesseract();
ocr.Language = OcrLanguage.EnglishFast;

using (var input = new OcrInput(@"images\image.png"))
{
    OcrResult result = ocr.Read(input);
    Console.WriteLine(result.Text);
}

Imports IronOcr

Private ocr As New IronTesseract()
ocr.Language = OcrLanguage.EnglishFast

Using input = New OcrInput("images\image.png")
	Dim result As OcrResult = ocr.Read(input)
	Console.WriteLine(result.Text)
End Using

更高精確度的細節語言示例

字典經過調校以提高準確性，但結果較慢。使用任何 OcrLanguage 的「最佳」變體。


//PM> Install-Package IronOcr.Languages.French
using IronOcr;

IronTesseract ocr = new IronTesseract();
ocr.Language = OcrLanguage.FrenchBest;

using (var input = new OcrInput(@"images\image.png"))
{
    OcrResult result = ocr.Read(input);
    Console.WriteLine(result.Text);
}


//PM> Install-Package IronOcr.Languages.French
using IronOcr;

IronTesseract ocr = new IronTesseract();
ocr.Language = OcrLanguage.FrenchBest;

using (var input = new OcrInput(@"images\image.png"))
{
    OcrResult result = ocr.Read(input);
    Console.WriteLine(result.Text);
}

'PM> Install-Package IronOcr.Languages.French
Imports IronOcr

Private ocr As New IronTesseract()
ocr.Language = OcrLanguage.FrenchBest

Using input = New OcrInput("images\image.png")
	Dim result As OcrResult = ocr.Read(input)
	Console.WriteLine(result.Text)
