Barcode Reader

[Joel Palmer]

I've been playing with your Barcode Reader and assume I am doing something wrong or missing something. 

First, is there a way to "push the Open button" from the library?  When I produce a barcode image, I'd like to just have it read that when I ask in code... not from the button.

Secondly and more important, I can't get a good read.  I have created a demo app that I'd be happy to share.  I print a 128 barcode to PNG file.  Then, I attempt to read the value back using the reader and it never returns the value I entered into the barcode.

Output Barcode to PNG File:

SaveFileDialog dialog = new SaveFileDialog()
{
    DefaultExt = "png",
    Filter = "png (*.png)|*.png"
};

if (dialog.ShowDialog() == true)
{
    using (Stream stream = dialog.OpenFile())
    {
        Telerik.Windows.Media.Imaging.ExportExtensions.ExportToImage(
            barCode,
            stream,
            new PngBitmapEncoder());
    }
}

Let me know if you want me to upload my demo app.

Hello Joel,

You can use the BarcodeDecoder class to decode images without the necessity of user interacting with the UI of the RadBarcode control to select an image. For example:

BarcodeDecoder decoder = new BarcodeDecoder();
decoder.ImageSource = new BitmapImage(uri);
decoder.DecodingComplete += Decoded;
decoder.StartDecoding();

I tested your code that exports the barcode control and the problem that I encountered when reading the exported image, was a result of the transparency. In order to resolve this problem you can set the Background of the control before exporting it. For example:

<telerik:RadBarcode128 Grid.Column="1" x:Name="barCode" Height="90" Width="370" Text="CODE 128"
    Background="White" />

On a side note, I would like to note that our barcode reader does not deal well with distorted, tilted or blurry images. In case this is a requirements for your application, I would recommend that you test the control thoroughly in order to decide whether it meets your requirements.
