How to stamp text & icons onto acquired images in Dynamic .NET TWAIN
Microsoft .NET Framework has its built-in method Graphics.DrawImage to add an image on another at the specified location.
Here is a simple sample in C#:
private void button2_Click(object sender, EventArgs e)
{
short index = m_ImageCore.ImageBuffer.CurrentImageIndexInBuffer;
System.Drawing.Bitmap original = m_ImageCore.ImageBuffer.GetBitmap(index);
System.Drawing.Image icon = System.Drawing.Image.FromFile("<the path for the stamp>");
Graphics g = Graphics.FromImage(original);
g.DrawImage(icon, itop, ileft, iwidth, iheight);
g.Dispose();
m_ImageCore.ImageBuffer.SetBitmap(index, original);
}
