Re: Missing functions from the image package

[Bill Denney]

Hi Alasdair,

I'm sure that new functions would be happily accepted.  Many of the
image functions are being actively worked on, but the effort often goes
to functions that the writer is currently in need of.  So, the best way
to have some of these functions is to write them, submit them, and then
use them with the large number of functions that others have written.

Have a good day,

Bill
