Hi friends,
i am working on a project in which i have to stored an image path into the database and after that when i have to display on htmlImageControl , retrieve the path from the database and display it on the image control.

Now there is a problem occurred after the image display..................I am having three Radiobuttons:

1)Gray Scale 2)Sepia 3)FullColor

now when user clicks one of them the image color should be displayed what user wants..........

I am confused how it can be achieved...... and now i am coming to this forum for the help.....

i have a function in asp.net which converts an image in gray scale but it returns a bitmap.

i don't know how to use this function........ so please help me

here is my function========================>

 Public Function ConvertToGrayscale(ByVal source As Bitmap) As Bitmap

        Dim bm As New Bitmap(source.Width, source.Height)

        Dim x

        Dim y

        For y = 0 To bm.Height

            For x = 0 To bm.Width

                Dim c As Color = source.GetPixel(x, y)

                Dim luma As Integer = CInt(c.R * 0.3 + c.G * 0.59 + c.B * 0.11)

                bm.SetPixel(x, y, Color.FromArgb(luma, luma, luma))

            Next

        Next

        Return bm

    End Function
