create a bitmap from an intptr to scanned data

[mickey]

Hi All
I have successfully retreived a pointer to scanned image data but all
efforts to turn this data into a bitmap have failed. Can anybody help?

Thanks

A pointer? That isn't likely. You would need the actual image data.

If it really is a handle to a GDI+ bitmap, then look at
Image.FromHBitmap(handle as IntPtr).

Did you already take a look at the overloaded 'Bitmap' constructor?
There is one overload ('New(Int32, Int32, Int32, PixelFormat, IntPtr)')
which expects a pointer to binary bitmap data in its last parameter.
