VintaSoft Barcode .NET SDK Discussions

Hi,

Alright I did now find out, that

new string()

does not work with all values from 0 to 255 in a character array. So the code would more or like look like this:

      var barcodeWriter = new Vintasoft.Barcode.BarcodeWriter ();
      barcodeWriter.Settings.Barcode = Vintasoft.Barcode.BarcodeType.DataMatrix;
      barcodeWriter.Settings.ProcessSpecialSymbols = true;

      var eciCharacterValueItem = NonDataFlags.CreateECICharacter (4);

      var encoding = Encoding.GetEncoding (1250);   //windows-1250 is Latin-2 equivalent
      var bytes = encoding.GetBytes ("ДЊ");

      var hacekC = new BinaryValueItem (bytes);

      barcodeWriter.Settings.ValueItems = new ValueItemBase[] { new DataMatrixTextValueItem ("some leading text", DataMatrixEncodingMode.Text), eciCharacterValueItem, hacekC };
      var outputImage = barcodeWriter.GetBarcodeAsBitmap ();

Questions are still the same.

hi,

Thanks for your reply.
So now I know I'm on the right way.

I have one question left.
In the AIM-Standard for ECI (page 34) there is a DataMatrix tag containing greek characters.
If you don't have the standard, there is a draft version here: http://www.aimglobal.org/standards/symb ... pubrev.pdf
that contains the exact same picture.
A part of the input string looks like the following:
"Irritating to eyes and skin/О•ПЃОµОёОЇО¶ОµО№ П„О± ОјО¬П„О№О± ОєО±О№ П„Ої ОґО­ПЃОјО±/\\"

When I decode the picture using bctester http://www.bctester.de/ I get the following output for the part with the greek characters:
"Irritating to eyes and skin/\\000009Åñåèßæåé ôá ìÜôéá êáé ôï äÝñìá /\\000003\\\\\"
when I try to encode the same input string (using ECI) with the VintaSoft library I get the following output:
"]d4*DEMO*Irritating to eyes and skin/\000009Åñåèßæåé ôá ìÜôéá êáé ôï äÝñìá/\000003\\\\"

The code I am using to reproduce this encoding is the following:

      var barcodeWriter = new Vintasoft.Barcode.BarcodeWriter ();
      barcodeWriter.Settings.Barcode = Vintasoft.Barcode.BarcodeType.DataMatrix;
      barcodeWriter.Settings.ProcessSpecialSymbols = true;

      var valueItems = GetEncodedValueItemsVintaSoft (dataInput);

      //latin-7 iso-8859-7 according to http://msdn.microsoft.com/en-us/library/system.text.encodinginfo.getencoding%28VS.80%29.aspx
      var greekEncoding = Encoding.GetEncoding (28597);

      barcodeWriter.Settings.ValueItems = new ValueItemBase[] {
          new TextValueItem ("Irritating to eyes and skin/"),
          NonDataFlags.CreateECICharacter(9),
          new BinaryValueItem (greekEncoding.GetBytes ("О•ПЃОµОёОЇО¶ОµО№ П„О± ОјО¬П„О№О± ОєО±О№ П„Ої ОґО­ПЃОјО±/")),
          NonDataFlags.CreateECICharacter(3),
          new TextValueItem ("\\\\")
        };

      var outputImage = barcodeWriter.GetBarcodeAsBitmap ();

As you can see there are some backslashes missing in the output. (before the ECI-characters and after the 3 at the latch to latin-1)
I tried to add the backslashes in the text but then the output also does not look as in the sample of the AIM standard:
]d4*DEMO*Irritating to eyes and skin/\\000009Åñåèßæåé ôá ìÜôéá êáé ôï äÝñìá/\\\000003\\\\

here is the code:

      //...

      barcodeWriter.Settings.ValueItems = new ValueItemBase[] {
          new TextValueItem ("Irritating to eyes and skin/\\"),
          NonDataFlags.CreateECICharacter(9),
          new BinaryValueItem (greekEncoding.GetBytes ("О•ПЃОµОёОЇО¶ОµО№ П„О± ОјО¬П„О№О± ОєО±О№ П„Ої ОґО­ПЃОјО±/\\")),
          NonDataFlags.CreateECICharacter(3),
          new TextValueItem ("\\\\")
        };

      //this also does not work as expected
      barcodeWriter.Settings.ValueItems = new ValueItemBase[] {
          new TextValueItem ("Irritating to eyes and skin/\\"),
          NonDataFlags.CreateECICharacter(9),
          new BinaryValueItem (greekEncoding.GetBytes ("О•ПЃОµОёОЇО¶ОµО№ П„О± ОјО¬П„О№О± ОєО±О№ П„Ої ОґО­ПЃОјО±/")),
          new TextValueItem ("\\"),
          NonDataFlags.CreateECICharacter(3),
          new TextValueItem ("\\\\")
        };

      //...

My question is now:
Am I supposed to add these backslash characters as a part of the ECI encoding procedure (then how should I add them correctly) or should this actually be done by the library.
Both of whick is OK for me, but I'm just trying to find out if this is an issue in the library that I'm trying to work around (which could be changed by your developers any time)
or if this is a wanted and specified behaviour on which I can trust that it won't be changed in the near future.

Anyways I need to know how the code should be changed on my side to reproduce this (probably standard-conformant) tag of the AIM standard.
Because it would be neccessary to encode such a text to be AIM standard conformant.
