PDF417 barcode not encoding tilde

Aspose.BarCode Product Family
1

When generating a PDF417 barcode, the ‘~’ characters are not encoded. For example, I use:


BarCodeBuilder b = new BarCodeBuilder() { SymbologyType = Symbology.Pdf417, AspectRatio = 4f, Pdf417ErrorLevel = Pdf417ErrorLevel.Level4, CodeLocation = CodeLocation.None };

b.CodeText = “A^aa^a^a^a^someFreeText~B^bb^b^b^b^OtherFreeText~C^cc^c^c^c^LastFreeText|”;

using (MemoryStream ms = new MemoryStream())
{
b.Save(ms, BarCodeImageFormat.Jpeg);
…
}

After I save the image to disk, or merge the image into a PDF document and scan the barcode, the string becomes:
A^aa^a^a^a^someFreeTextB^bb^b^b^b^OtherFreeTextC^cc^c^c^c^LastFreeText|

Please advise on how to correct this. Thank you.

Shahzad,


Thank you for your update. If this is a bug, do you have any estimate on when it will be corrected? I am getting near the end of a large integration project, and this barcode is required for one of the final pieces of that project.

Thanks again,
Casey

I found that if I set if Pdf417CompactionMode to binary that the tilde will remain in the barcode, that seems to work for now.


Thanks,
