IronOCR 支持 125 种国际语言，但只有 英语 作为标准配置安装在 IronOCR 中。
您可以轻松地将其他语言包添加到您的 C#、VB 或 ASP .NET 通过 NuGet 或作为 Dlls（可下载并添加为项目引用）添加到项目中。
代码示例
国际语言范例
//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 UsingVB C#
垂直书写语言示例
为竖写语言调整词典。 使用韩国和日本 OcrLanguage 的 "竖写 "变体。
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 UsingVB C#
自定义语言示例
使用您下载或自行训练的任何 Tesseract .Traineddata 语言文件
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 UsingVB C#
多种语言示例
同时使用多种语言。
//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 UsingVB C#
更快的语言示例
为提高速度而调整的字典。 使用任何 OcrLanguage 的 "快速 "变体。
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 UsingVB C#
更高精度的详细语言示例
为准确性而调整的字典，但结果更慢。 使用任何 OcrLanguage 的 "最佳 "变体。
//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)
End UsingVB C#
