Sorry, I forgot to tell: the ratio is just a float used to scale the
image on the screen. For testing purpose, it is equal to 1.0
The problem is that the image is drawing the same as before.

I tried this:
NSImageRep *rep=[[currentImage representations] objectAtIndex:0];
ratio=[tempImage ratio];
[currentImage
drawInRect:NSMakeRect(bounds.size.width/2.0-
center.x*ratio,bounds.size.height/2.0-center.y*ratio,[rep
pixelsWide]*ratio,[rep pixelsHigh]*ratio)
fromRect:NSMakeRect(0.0,0.0,[rep pixelsWide],[rep
pixelsHigh])
operation:NSCompositeSourceOver
fraction:1.0];
Instead of:
NSSize size=[currentImage size];
ratio=[tempImage ratio];
[currentImage
drawInRect:NSMakeRect(bounds.size.width/2.0-
center.x*ratio,bounds.size.height/2.0-
center.y*ratio,size.width*ratio,size.height*ratio)
fromRect:NSMakeRect(0.0,0.0,size.width,size.height)
operation:NSCompositeSourceOver
fraction:1.0];
But it doesn't work...
Since you don't say what the "ratio" method does, I can't say whether
that might be affecting the output. Is it possible that the ratio
method was updated too and is undoing the affects of using the pixel
dimensions?
Also, in what way is it failing? Is it drawing the same as before, or
is it not drawing at all?
