LEADTOOLS v18（即LEADTOOLS Anywhere）將其世界領先的成像技術擴展到了WinRT、iOS、Android、Windows Phone和Linux等平臺。不僅如此，用戶還可以在所有流行平臺中實現查看、注釋和標記、OCR、條形碼、PDF、圖像格式、壓縮和圖像處理等功能。

LEADTOOLS在每個開發平臺上面都提供了一組非常相似的開發庫，這是LEADTOOLS的一個非常明顯的優勢，讓開發者既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。

LEADTOOLS Anywhere功能

• 提供了專門針對.NET, HTML5, WinRT, Windows Phone, iOS, OS X和Android的圖像查看器；
• 支持加載、轉換和保存超過150種圖像格式；
• 支持條形碼讀寫，包括：QR碼，PDF417，二維碼，UPC/EAN等；
• OCR將圖像轉換為可搜索的文本，PDF，DOC；
• 全面的注釋和標記，包括幾何形狀，便條，編校，亮點和橡皮圖章；
• 擁有超過200多種圖像處理功能，如圖像增強，圖像糾偏等

接下來，我們就一起展示一下LEADTOOLS Anywhere如何在每個平臺上面讀取條形碼。

.NET

System.Drawing.Bitmap bitmap = ... //
// Get a LEADTOOLS RasterImage from the platform image
RasterImage rasterImage = RasterImageConverter.FromImage(bitmap);
// Create a LEADTOOLS Barcode Engine instance
private BarcodeEngine barcodeEngine = new BarcodeEngine();
// Read the first barcode found in the image
BarcodeData barcodeData = barcodeEngine.Reader.ReadBarcode(rasterImage,
LogicalRectangle.Empty, BarcodeSymbology.Unknown);
// For this example, simply output the barcode type, location and data in the console
if (barcodeData != null) {
Console.WriteLine("Symbology:{0}", barcodeData.Symbology);
Console.WriteLine("Location:{0},{1},{2},{3}", barcodeData.Bounds.X,
barcodeData.Bounds.Y, barcodeData.Bounds.Width, barcodeData.Bounds.Height);
Console.WriteLine("Value:{0}", barcodeData.Value);
} else {
Console.WriteLine("No barcodes found");
}

WinRT & Windows Phone

Windows.UI.Xaml.Media.ImageSource imageSource = ... //
// Get a LEADTOOLS RasterImage from the platform image
RasterImage rasterImage = RasterImageConverter.ConvertFromImageSource(
imageSource, ConvertFromImageOptions.None);
// Create a LEADTOOLS Barcode Engine instance
private BarcodeEngine barcodeEngine = new BarcodeEngine();
// Read the first barcode found in the image
BarcodeData barcodeData = barcodeEngine.Reader.ReadBarcode(rasterImage,
LogicalRectangle.Empty, BarcodeSymbology.Unknown);
// For this example, simply output the barcode type, location and data in the console
if (barcodeData != null) {
Console.WriteLine("Symbology:{0}", barcodeData.Symbology);
Console.WriteLine("Location:{0},{1},{2},{3}", barcodeData.Bounds.X,
barcodeData.Bounds.Y, barcodeData.Bounds.Width, barcodeData.Bounds.Height);
Console.WriteLine("Value:{0}", barcodeData.Value);
} else {
Console.WriteLine("No barcodes found");
}

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 Barcode Engine instance
LTBarcodeEngine* barcodeEngine = [LTBarcodeEngine new];
// Read the first barcode found in the image
LTBarcodeData* barcodeData = [barcodeEngine.reader readBarcode:rasterImage
searchBounds:LeadRect_Empty() symbologies:nil symbologiesCount:0 error:nil];
// For this example, simply retrieve the barcode type, location and data
if(barcodeData != nil) {
NSLog(@"Symbology:%u", barcodeData.symbology);
NSLog(@"Location:%u,%u,%u,%u", barcodeData.bounds.x, barcodeData.bounds.y,
barcodeData.bounds.width, barcodeData.bounds.height);
NSLog(@"Value:%@", barcodeData.value);
} else {
NSLog(@"No barcodes found");
}

Android

android.graphics.Bitmap bitmap = ... //
// Get a LEADTOOLS RasterImage from the platform image
RasterImage rasterImage = RasterImageConverter.convertFromBitmap(
bitmap, ConvertFromImageOptions.NONE);
// Create a LEADTOOLS Barcode Engine instance
private BarcodeEngine barcodeEngine = new BarcodeEngine();
// Read the first barcode found in the image
BarcodeData barcodeData = barcodeEngine.getReader().readBarcode(
rasterImage, LeadRect.getEmpty(), BarcodeSymbology.UNKNOWN);
// For this example, simply output the barcode type, location and data in the console
if (barcodeData != null) {
Log.i("LEADTOOLS.BarcodeDemo", String.format("Symbology:%s", barcodeData.getSymbology()));
Log.i("LEADTOOLS.BarcodeDemo", String.format("Location:%1$s,%2$s,%3$s,%4$s",
barcodeData.getBounds().getX(), barcodeData.getBounds().getY(),
barcodeData.getBounds().getWidth(), barcodeData.getBounds().getHeight()));
Log.i("LEADTOOLS.BarcodeDemo", String.format("Value:%s", barcodeData.getValue()));
} else {
Log.i("LEADTOOLS.BarcodeDemo", "No barcodes found");
}
