VB NET Convert a file from .Ico to .Bmp

  • 아티클

In this example, using the Bitmap class included in the System.Drawing namespace, a file is converted from .Ico to .Bmp to display it in a PictureBox.
This is necessary because the .Ico format is not supported by the PictureBox control.

VB 

Public Class Form1
  Public Function FromIconToBitmap(ByVal icon As Icon) As Bitmap
    Dim bmp As New Bitmap(icon.Width, icon.Height)
    Using gp As Graphics = Graphics.FromImage(bmp)
      gp.Clear(Color.Transparent)
      gp.DrawIcon(icon, New Rectangle(0, 0, icon.Width, icon.Height))
    End Using
    Return bmp
  End Function
 

  Private Sub Button1_Click(sender As System.Object,
                            e As System.EventArgs) Handles Button1.Click
    Dim icon As Icon = My.Resources.Resources.Icon1
    PictureBox1.Image = FromIconToBitmap(icon)
  End Sub
End Class
