LEADTOOLS最近發布了v18版本，這個版本也被稱為LEADTOOLS Anywhere™，他將世界最領先的成像技術擴展到iOS，Android和Linux OS X等平臺。不僅僅是Windows平臺，他讓所有流行的平臺都能夠實現查看者，注釋和標記，OCR，條碼，PDF，圖像格式，壓縮，圖像處理等更多圖像OCR功能。

　　每個使用LEADTOOLS的開發者能夠在每個開發平臺上使用一組非常相似的庫進行程序開發。這是其的一個明顯優勢，讓開發者即能夠開發原生的應用程序，又不用花費太多的時間進行完全的代碼重寫。

新版本功能亮點：

• 多平臺原生圖像查看器：.NET、HTML5、WinRT、iOS、OS X和Android
• 支持加載、轉換和保存超過150種圖像格式
• 先進的位深度，色彩空間和壓縮支持，包括PDF/ A，PDF，JPEG，JPEG 2000，TIFF，JBIG2等
• OCR將圖像轉換為可搜索的文本，PDF，DOC
• 條形碼讀寫支持，包括：QR碼，PDF417，二維碼，UPC/EAN等
• 支持注釋和標記，包括幾何形狀，便簽，重做，高亮和橡皮擦

　　接下來，我們將展示LEADTOOLS對于各個平臺不同的OCR代碼示例。

.NET

System.Drawing.Bitmap bitmap = ... // 
// Get a LEADTOOLS RasterImage from the platform image
RasterImage rasterImage = RasterImageConverter.FromImage(bitmap);
// Create a LEADTOOLS OCR Document instance
IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineAdvantage, false);
ocrEngine.Startup(null, null, null, Application.CommonAppDataPath);
IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument();
// Add the page to the document and recognize it
IOcrPage ocrPage = ocrDocument.Pages.AddPage(rasterImage, null);
// Recognize the image as text
string text = ocrPage.RecognizeText(null);
// Do something with 'text'

WinRT

Windows.UI.Xaml.Media.ImageSource imageSource = ... //
// Get a LEADTOOLS RasterImage from the platform image
RasterImage rasterImage = RasterImageConverter.ConvertFromImageSource(imageSource, ConvertFromImageOptions.None);
// Create a LEADTOOLS OCR Document instance
IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false);
ocrEngine.Startup(null, null, string.Empty, Package.Current.InstalledLocation.Path);
IOcrDocument ocrDocument = ocrEngine.DocumentManager.CreateDocument();
// Add the page to the document and recognize it
IOcrPage ocrPage = ocrDocument.Pages.AddPage(rasterImage, null);
// Recognize the image as text
string text = ocrPage.RecognizeText(null);
// Do something with 'text'

iOS & OS X

UIImage* uiImage = ... //
// Get a LEADTOOLS RasterImage from the platform image
LTRasterImage* rasterImage = [LTRasterImageConverter convertFromImage:uiImage
     options:LTConvertFromImageOptions_None
       error:nil];
// Create a LEADTOOLS OCR Document instance
[ocrEngine startup:nil workDirectory:nil startupParameters:[[NSBundle mainBundle] bundlePath];
LTOcrDocument* ocrDocument = [ocrEngine.documentManager createDocument];
// Add the page to the document and recognize it
LTOcrPage* ocrPage = [ocrDocument.pages addPageWithImage:rasterImage
   target:nil
   selector:nil
   error:nil];
// Recognize the image as text
NSString* text = [ocrPage recognizeText:nil selector:nil error:nil];
// Do something with 'text'

Android

android.graphics.Bitmap bitmap = ... //
// Get a LEADTOOLS RasterImage from the platform image
RasterImage rasterImage = RasterImageConverter.convertFromBitmap(bitmap, ConvertFromImageOptions.NONE);
// Create a LEADTOOLS OCR Document instance
OcrEngine ocrEngine = OcrEngineManager.createEngine(OcrEngineType.Advantage);
ocrEngine.startup(null, "", null, this.getApplicationInfo().dataDir);
OcrDocument document = ocrEngine.getDocumentManager().createDocument();
// Add the page to the document and recognize it
OcrPage ocrPage = document.getPages().addPage(image, null);
// Recognize the image as text
String text = ocrPage.recognizeText(this);
// Do something with 'text'
