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.

And only now you tell me about it... after i've spent so many hours playing
around with it...
I feel betrayed.. :(
