问题
I have tried to read IMB barcode from an image with the below code snippet, but it always return null. I have also tried with the IMB barcode images in the blackbox testing below, but doesn't work.
https://github.com/micjahn/ZXing.Net/tree/master/Source/test/data/blackbox/imb-1
private static void Decode()
{
Bitmap bitmap = new Bitmap(@"\07.png");
try
{
MemoryStream memoryStream = new MemoryStream();
bitmap.Save(memoryStream, ImageFormat.Bmp);
byte[] byteArray = memoryStream.GetBuffer();
ZXing.LuminanceSource source = new RGBLuminanceSource(byteArray, bitmap.Width, bitmap.Height);
var binarizer = new HybridBinarizer(source);
var binBitmap = new BinaryBitmap(binarizer);
IMBReader imbReader = new IMBReader();
Result str = imbReader.decode(binBitmap);
}
catch { }
}

I have solved this problem by using the below code snippet shared through the below link. https://github.com/micjahn/ZXing.Net/issues/59
private static void Decode2()
{
var bitmap = new Bitmap(@"\07.png"); // make sure that the file exists at the root level
try
{
var imbReader = new BarcodeReader
{
Options =
{
PossibleFormats = new List<BarcodeFormat> {BarcodeFormat.IMB}
}
};
var result = imbReader.Decode(bitmap);
if (result != null)
System.Console.WriteLine(result.Text);
else
System.Console.WriteLine("nothing found");
}
catch (System.Exception exc)
{
System.Console.WriteLine(exc.ToString());
}
}
