Thanks everyone for the advice on how to load images into a
screensaver. Now I'm trying to make the images move, and am doing
the obvious in animateOneFrame:
[myImageView setFrame:NSOffsetRect([myImageView frame],1,1)];
The image moves, and the quality is acceptable, but there's a twinge
of flickering about it -- it's not nearly as smooth as the Aqua Icons
screensaver.
Any ideas as to how I can remedy this? I'm assuming that, as with
most things that I've been doing, lately, that this is a limitation
in my knowledge rather than a problem with Cocoa.
In an air of experimentation I did override the backingStoreType; I
got interesting displays with NSBackingStoreRetained and
NSBackingStoreNonretained -- the screen alternated between
myImageView on a black background and a completely white screen --
obviously not what I was hoping for.
TIA as usual,
Michael
