Detailed Description

Represents the barcode's region.

This sample shows how to draw edges of the barcode region, then fill it.

[C#]
using (BarCodeReader reader = new BarCodeReader(@"c:\test.jpg",BarCodeReadType.Code39Standard))
{
int counter = 0;
while(reader.Read())
{
Console.WriteLine("BarCode Type: "+reader.GetReadType());
Console.WriteLine("BarCode CodeText: " + reader.GetCodeText());
BarCodeRegion region = reader.GetRegion();
if(region != null)
{
Image img = System.Drawing.Image.FromFile(file);
Graphics g = Graphics.FromImage(img);
region.DrawBarCodeEdges(g,new Pen(Color.Red,1f));
img.Save(string.Format(@".\edge_{0}.png" ,counter++));
region.FillBarCodeRegion(g,Brushes.Green);
img.Save(string.Format(@".\fill_{0}.png", counter++));
}
}
}
[VB.NET]
Using reader As BarCodeReader = New BarCodeReader("c:\test.jpg", BarCodeReadType.Code39Standard)
Dim counter As Integer
While reader.Read()
counter = counter + 1
Console.WriteLine("BarCode Type: " + reader.GetReadType().ToString)
Console.WriteLine("BarCode CodeText: " + reader.GetCodeText())
Dim region As BarCodeRegion
region = reader.GetRegion()
If Not region Is Nothing Then
Dim img As Image = System.Drawing.Image.FromFile("c:\test.jpg")
Dim g As Graphics = Graphics.FromImage(img)
region.DrawBarCodeEdges(g, New Pen(Color.Red, 1.0F))
img.Save(String.Format(".\edge_{0}.png", counter))
region.FillBarCodeRegion(g, Brushes.Green)
img.Save(String.Format(".\fill_{0}.png", counter))
End If
End While
End Using
