Change color in bitmap on web form

Question

Hi, I've seen quite a bit on changing a selected RGB color to another in a image within a Windows Form, but not in a Web Form. I've come close with trying ColorMap but when I try to create ImageAttributes the test image doesn't render. Here's a snippet (and yes, it's VB.net) where the red pixels would change to blue: Dim imgAtts As ImageAttributes = New ImageAttributes() Dim clrMap(1) As ColorMap clrMap(0) = New ColorMap() clrMap(0).OldColor = Color.FromArgb(255, 0, 0) clrMap(0).NewColor = Color.FromArgb(0, 0, 255) Dim strX As String Try imgAtts.SetRemapTable(clrMap, ColorAdjustType.Default) strX = "YES!" Catch strX = "Nope" End Try Any ideas? Thanks, Walks
