Stretchblt in .NET

[Craig Gemmill]

Or you can just use the Graphics.DrawImage method. It will stretch the image for you.

        Dim destinationImage As New Bitmap(100, 100)
        Dim sourceImage As Image = PictureBox1.Image
        Dim g As Graphics

        g = Graphics.FromImage(destinationImage)

        g.DrawImage(sourceImage, New Rectangle(0, 0, destinationImage.Width, destinationImage.Height), 0, 0, sourceImage.Width, sourceImage.Height, GraphicsUnit.Pixel)

        g.Dispose()

        PictureBox2.Image = destinationImage
