From DIB to BITMAP

thank you for your help :
but now I am adding it to listview from the imagelist after adding the bitmap to the listview,
and I have added a function on listView1_SelectedIndexChanged

private void listView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        for (int k = 0; k < listView1.CheckedIndices.Count; k++)
        {
                     pictureBox1.Image = imageList1.Images[listView1.CheckedIndices[k]];
            pictureBox1.Visible = true;
            pictureBox1.Size = new Size(200, 256);
        }

    }

but it is giving a small picture size with low riselution
how can I see the real image riselution as it is scanned???
regards...
