>Tim and I wanted to avoid the kind of type proliferation in vil that we felt made vil1 very hard to understand.


Not being a very sophisticated user of vil1, I didn’t feel that its basic functionality was hard to understand. The vil1_image pointer is generic for argument passing, and then one usually converts back and forth to a memory image of some type. However these types are typically limited to a few, such as unsigned char, vil1_rgb<unsigned char>, float.  Isn’t this easy to understand?
