How to convert the format of images in VB.NET?

To convert the format of an image you need to use the System.Drawing namespace. Using this code you can convert to a variety of graphic file formats, such as GIF or JPG.

The following example converts a user prompted Bitmap image file into .Gif format.

 
File ImageConverter.vb
Imports System
Imports System.Drawing
Class ConvertImages
 Shared Sub main()
  Dim str As String
  Console.Write("Path of the Image File to Convert :")
  str = Console.ReadLine()
  'Initialize the bitmap object by supplying the image file path
  Dim bmp As New Bitmap(str)
  bmp.Save(str + ".gif",  System.Drawing.Imaging.ImageFormat.Gif)
  Console.Write("Image Sucessfully Converted to " & str & ".gif")
 End Sub
End Class
