In VB:
Dim your new bitmap

Dim nb as Bitmap=New Bitmap(100,100)
Dim g as Graphics=Graphics.FromImage(nb)
g.DrawImage(oldBitmap,new Rectangle(0,0,100,100), New Rectangle(0,0,25,25),
PixelFormat....)

Convert that in C#

Hi,

Create a new Bitmap of the desired size, wrap a Graphics around it,
and draw the original onto the new one. Then Destroy() the Graphics
and you should be all set.

Thanks,
