LEADTOOLS最近發(fā)布了v18版本，這個(gè)版本也被稱為LEADTOOLS Anywhere™，他將世界最領(lǐng)先的成像技術(shù)擴(kuò)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?qū)崿F(xiàn)查看者，注釋和標(biāo)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(gè)使用LEADTOOLS的開發(fā)者能夠在每個(gè)開發(fā)平臺上使用一組非常相似的庫進(jìn)行程序開發(fā)。這是其的一個(gè)明顯優(yōu)勢，讓開發(fā)者即能夠開發(fā)原生的應(yīng)用程序，又不用花費(fèi)太多的時(shí)間進(jìn)行完全的代碼重寫。

新版本功能亮點(diǎn)：

• 多平臺原生圖像查看器：.NET、HTML5、WinRT、iOS、OS X和Android
• 支持加載、轉(zhuǎn)換和保存超過150種圖像格式
• 先進(jìn)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(zhuǎn)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(biāo)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(gè)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'
