If you are handling binary data in barcodes such as you find in some 2-D barcodes (PDF417, QrCode or DataMatrix) then the following method will allow you to create a byte array that contains the original binary data from the barcode – including all the null and 8-bit values.<\/p>\n
1. Using Quoted printable Encoding<\/p>\n
barcode.Encoding = 1;<\/p>\n
This will return the barcode value using either printable characters or =XX where XX is a hex value for non-printable characters (e.g for null you get =00). By default the data will be potentially be handled as if it contains utf-8 encoded data.<\/p>\n
2. Convert the quoted printable output from GetBarString to a byte array using the following function:<\/p>\n
[code]
\n private byte[] convertQPToByteArray(string qpString)
\n {
\n \/\/ Assess how many bytes required<\/p>\n
int c = 0;<\/p>\n
for (int i = 0; i < qpString.Length; i++, c++)\n if (qpString[i] == '=')\n i += 2;\n\n byte[] binaryData = new byte[c];\n\n int zero = Convert.ToInt16('0');\n\n c = 0;\n for (int i = 0; i < qpString.Length; i++, c++)\n {\n if (qpString[i] == '=')\n {\n binaryData[c] = (byte) int.Parse(qpString.Substring(i + 1, 2), System.Globalization.NumberStyles.HexNumber);\n i += 2;\n }\n else\n {\n binaryData[c] = Convert.ToByte(qpString[i]);\n }\n }\n\n return binaryData;\n }\n[\/code]\n<\/p>\n","protected":false},"excerpt":{"rendered":"
