Re: Article: Functional image processing in D

[Phil]

This is very cool. What are the performance implications of 
treating colour images as arrays of tuples rather than a flat 
array? For example, if I wanted to iterate through every channel 
of every pixel in an RGB image or modify the R channel of every 
pixel, could I generally expect the compiler to optimise the 
extra overhead away? Also, do you have any ideas on how you could 
vectorise code like this while still providing a nice API?
