The Photoshop approach may yield better looking results.
But, if you want to do it in code, something along these lines should
do it. Completely untested.
-(NSImage*) imageFromImage:(NSImage*) image withOpacity:(float) newOpacity {
NSImage* new = [[NSImage alloc] initWithSize:[image size]];
[new lockFocus];
[image disolveToPoint:NSZeroPoint fraction:newOpacity];
[new unlockFocus];
return [new autorelease];
}
Someone wiser may have a slicker approach.
Note - you'll want to cache those images up in advance or else your
animation would probably be choppy.

Hi guys. I would like to ask if any of you could come up with a solution on
setting the status item's transparency. I'm kinda new to doing lockFocus on
NSImages, and setting transparency / alpha stuff in them.
I would like to have a status item that "softly blinks" when a background
process is being done inside the application.
Many thanks in advance :D
