successfully implemented other controls like zooming,filters,grayscale

I'm creating some barcode generator, and I want to save generated
barcode to database, but I have a problem when I want to get bytes
from PictureBox Image. It says that Image property is null. That's
hapening because barcode is drawn on the PictureBox(not in Image
property). I think that I could solve it by converting graphic to
bitmap, but I don't know how?. Here's the code:

class="language-cs">Graphics graphics =
barcodePictureBox.CreateGraphics();
graphics.FillRectangle(new SolidBrush(SystemColors.Control),
new Rectangle(0, 0, barcodePictureBox.Width,
barcodePictureBox.Height)); EAN13 = new Ean13();
EAN13.CountryCode = "68

I was using the following code to enter an image url at
TextBox1 and display it in
PictureBox1.Everything worked.

But suddenly the
displayed image quality is lower than the original link. I've tried
PictureBox1.Load(TextBox1.Text) and changing
SizeMode still the same result.

class="language-vb">Imports System.Net Public Class Form1
Dim client As WebClient Private Sub Button1_Click(ByVal sender
As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
client = New WebClient() Dim ImageInBytes() As
Byte = client.DownloadData(TextBox1.Text) Dim ImageStrea
