I left out your other questions because I am confused on those issues as well. However, assuming you get them figured out, I would appreciate it if you took some additional time to update the relevant docbook documentation to help relieve everybody's confusion on these matters. > Since "defined" does not have a corresponding "user data" pointer, it > seems that whether a point is "defined" or not must be determinable > solely from the x,y coordinates themselves and not from the 2D data > values (or accompanying "data valid" flags array).

I can help you out a bit with this one. There is an example of how "defined" is used in the C version of example 16. And, FWIW, I think we should have adopted a more general API for "defined". However, I guess nobody cares too much about it because of its limitations. For example, the "defined" part of example 16 looks pretty good at normal resolution, but you get a real mess at lower resolutions. Thus, I don't think there is any language interface that currently propagates what C does with "defined", and I suggest you skip it for Ruby as well. Alan __________________________ Alan W.
