Hi,

scaling gives good results, but the scaling code is really slow. The problem 
is, that the code accesses pixels using readpixel(x,y,x,y,pixel). This is 
probably the slowest way to access pixels. I think basically it would be the 
best idea to read a whole line from an image at a time. This could be done by 
calling readpixel (0,y,width(),y,line). But is this the most efficient way or 
is it better to use iterators. If yes, how can I use the iterators to read a 
whole line?

Michael
