Introduction
I am just trying to explain, how can use "ean13.tff" font in c#.net.
First you downlaod / copy (from your source folder) ean13.tff font.
Then install this font your font directory ( C:\Windows\fonts). Then try to run project or
WINFOnt.exe file .
Using the code
In my sample Code have two methods
1. EAN8(string chaine)
public string EAN8(string chaine)
{
int i;
double checksum;
string CodeBarre = "";
checksum = 0;
if (chaine.Length == 7)
{
for (i = 1; i <= 7; i++)
{
int L1 = Convert.ToChar(chaine.Substring(i - 1, 1));
if ((L1 < 48) || (L1 > 57))
{
i = 0;
break;
}
}
if (i == 8)
{
for (i = 7; i > 0; i = i - 2)
{
checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));
}
checksum = checksum * 3;
for (i = 6; i > 0; i = i - 2)
{
checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));
}
chaine = chaine + (10 - checksum % 10) % 10;
CodeBarre = ":";
for (i = 1; i <= 4; i++)
{
CodeBarre = CodeBarre + Convert.ToChar(65 + Convert.ToInt32(chaine.Substring(i - 1, 1)));
}
CodeBarre = CodeBarre + "*";
for (i = 5; i <= 8; i++)
{
CodeBarre = CodeBarre + Convert.ToChar(97 + Convert.ToInt32(chaine.Substring(i - 1, 1)));
}
CodeBarre = CodeBarre + "+";
}
}
return CodeBarre;
}
EAN13(string chaine)
public object EAN13(string chaine)
{
object functionReturnValue = null;
int i;
int checksum = 0;
int first;
string CodeBarre;
bool tableA;
functionReturnValue = "";
if (chaine.Length == 12)
{
for (i = 1; i <= 12; i++)
{
int L1 = Convert.ToChar(chaine.Substring(i - 1, 1));
if (L1 < 48 || L1 > 57)
{
i = 0;
break;
}
}
if (i == 13)
{
for (i = 12; i >= 1; i += -2)
{
checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));
}
checksum = checksum * 3;
for (i = 11; i >= 1; i += -2)
{
checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));
}
chaine = chaine + (10 - checksum % 10) % 10;
CodeBarre = chaine.Substring(0, 1) + Convert.ToChar(65 + Convert.ToInt32((chaine.Substring(1, 1))));
first = Convert.ToInt32(chaine.Substring(0, 1));
for (i = 3; i <= 7; i++)
{
tableA = false;
switch (i)
{
case 3:
switch (first)
{
case 0:
case 1:
case 2:
case 3:
tableA = true;
break;
}
break;
case 4:
switch (first)
{
case 0:
case 4:
case 7:
case 8:
tableA = true;
break;
}
break;
case 5:
switch (first)
{
case 0:
case 1:
case 4:
case 5:
case 9:
tableA = true;
break;
}
break;
case 6:
switch (first)
{
case 0:
case 2:
case 5:
case 6:
case 7:
tableA = true;
break;
}
break;
case 7:
switch (first)
{
case 0:
case 3:
case 6:
case 8:
case 9:
tableA = true;
break;
}
break;
}
if (tableA)
{
CodeBarre = CodeBarre + Convert.ToChar(65 + Convert.ToInt32(chaine.Substring(i - 1, 1)));
}
else
{
CodeBarre = CodeBarre + Convert.ToChar(75 + Convert.ToInt32(chaine.Substring(i - 1, 1)));
}
}
CodeBarre = CodeBarre + "*";
for (i = 8; i <= 13; i++)
{
CodeBarre = CodeBarre + Convert.ToChar(97 + Convert.ToInt32(chaine.Substring(i - 1, 1)));
}
CodeBarre = CodeBarre + "+";
functionReturnValue = CodeBarre;
}
}
return functionReturnValue;
}
Next Step is ' add on digit method' for add extra digit in barcode
AddOn(string chaine)
public string AddOn(string chaine)
{
int i;
int checksum = 0;
string AddOnn = "";
bool tableA;
if (chaine.Length == 2 || chaine.Length == 5)
{
for (i = 1; i < chaine.Length; i++)
{
int L1 = Convert.ToChar(chaine.Substring(i - 1, 1));
if (L1 < 48 || L1 > 57)
{
break;
}
if (chaine.Length == 2)
{
checksum = 10 + Convert.ToInt32(chaine) % 4;
}
else if (chaine.Length == 5)
{
for (i = 1; i == 5; i = i - 2)
{
checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));
}
checksum = (checksum * 3 + Convert.ToInt32(chaine.Substring(2, 1)) * 9 + Convert.ToInt32(chaine.Substring(4, 1)) * 9) % 10;
}
AddOnn = "[";
for (i = 1; i <= chaine.Length; i++)
{
tableA = false;
switch (i)
{
case 1:
int[] str = { 4, 9, 10, 11 };
for (int j = 0; j < str.Length; j++)
{
if (str[j] == checksum)
{
tableA = false;
break;
}
}
break;
case 2:
int[] str1 = { 1, 2, 3, 5, 6, 7, 10, 12 };
for (int j = 0; j < str1.Length; j++)
{
if (str1[j] == checksum)
{
tableA = false;
break;
}
}
break;
case 3:
int[] str2 = { 0, 2, 3, 6, 7 };
for (int j = 0; j < str2.Length; j++)
{
if (str2[j] == checksum)
{
tableA = false;
break;
}
}
break;
case 4:
int[] str3 = { 1, 3, 4, 8, 9 };
for (int j = 0; j < str3.Length; j++)
{
if (str3[j] == checksum)
{
tableA = false;
break;
}
}
break;
case 5:

}
if (tableA)
AddOnn = AddOnn + Convert.ToChar(65 + Convert.ToInt32(chaine.Substring(i - 1, 1)));
else
