Re: Rotating an NSView before printing

I wrote a printer emulation view that needed to rotate itself for 
landscape printing.
In the init method, I create and retain a NSAffineTransform to handle 
he rotation
       toLandscape = [[NSAffineTransform transform] retain];
       //we move down and then rotate
       [toLandscape translateXBy:0 yBy:[self frame].size.height];
       [toLandscape rotateByDegrees:-90];

In the drawRect: method, I apply the transform if needed
   //each new page needs to have transformation applied
   if (isLandscape) {
       [toLandscape concat];
   }
   //draw stuff
