Hello,
For some reason this ImageAttributes isn't doing what I tell it.  I'm
not sure what I am missing.  I am trying to get background of the image
to display as transparent.  But it draws the image unchanged.  Here's
my code.

    Dim ImgColorMap(0) As System.Drawing.Imaging.ColorMap
        Dim BackColor As Color
        'Draw the Background
        graph.DrawImage(BackGroundImage, 0, 0)

        'Draw the board
        BackColor = BoardImages(0).GetPixel(0, 0)
        ImgColorMap(0) = New System.Drawing.Imaging.ColorMap
        ImgColorMap(0).OldColor = New Color
        ImgColorMap(0).OldColor.FromArgb(BackColor.A, BackColor.R,
BackColor.G, BackColor.B)
        ImgColorMap(0).NewColor = New Color
        ImgColorMap(0).NewColor.FromArgb(0, 0, BackColor.G, 0)
        BoardImageAttributes = New
System.Drawing.Imaging.ImageAttributes
        BoardImageAttributes.SetRemapTable(ImgColorMap)

        graph.DrawImage(BoardImages(0), New Rectangle(50, 50, 50, 50),
28, 28, 50, 50, GraphicsUnit.Pixel, BoardImageAttributes)

This assigns an empty Color value to OldColor (i.e. black).

FromArgb returns the new value. It is a static method, so it does not
modify the Color value in the OldColor property itself. What you want is
more like:

          ImgColorMap(0).OldColor = Color.FromArgb(BackColor.A '...

Okay,
I removed those New keywords for OldColor and NewColor.  I am still
getting a drawn image with no changed colors.
Does it make a difference that I am writing all this in a class and not
the form itself?
