[net.micro.amiga] Help on Double Buffering Needed

johnhlee@miro.Berkeley.EDU (John H. Lee) (10/03/86)

I'm distributing this for a friend who needs help on double buffering.
-------------------------------------------------------------------------

I am writing a program which uses color cycling and double buffering.  I am
using Intuition to set up the screen and windows and then I make another
viewport with makeVPort() to be used as the alternate bitmap.
I found however, that I can only cycle the colors in the second bitmap, which
I created.  This happens after I call the MrgCop() function.  Somebody, 
please help me!  Everything else works, except this.  Tell me what does
MrgCop do besides change the copper instructions pointed to in the View
structure.

Well, if anyone can help him, please E-Mail me at ...!ucbvax!ucbmiro!johnhlee
