Inserting 1 bitmap in to another
by:Stu

Hi,
What is the quickest (performance wise) way to copy one small bitmap to
certain coordinates of a bigger bitmap? I'm currently doing it by looping
through each pixel....and I get the feeling I've missed something a little
more elegant!
Thanks in advance,
Stew

\\Dim b1 As New Bitmap(...)
Dim b2 As New Bitmap(...)
Dim g As Graphics = Graphics.FromImage(b1)
g.DrawImage(b2, ...)
g.Dispose()
b1.Save(...)
b1.Dispose()
b2.Dispose()

| | What's wrong with DrawImage?
\\\\\\\\\Function StampImage(ByVal Source As Image, ByVal Stamp As Image, Coord as
Point) As Image
Dim NewBmp As New Bitmap(Source)
Dim NewGraphics As Graphics = Graphics.FromImage(NewBmp)
NewGraphics.DrawImage(Stamp, Coord )
Return NewBmp
End Function

| | Watch yourself here, though. This knida stuff can become extremely amusing,
and many hours can be wasted tinkering the GDI+ namespace. It really needs
some kind of restricted access/parental gudiance/disclaimer thingy to be
smacked on the front of it.
Terribly addictive stuff that... so be warned.
