Subject: wish: r.grow2 floating point support

Platform: GNU/Linux/i386
grass obtained from: Mirror of Trento site
grass binary for platform: Compiled from Sources
GRASS Version: 5.3 cvs apr 2004

It would be nice if r.grow2 supported FCELL & DCELL maps.

Current workaround is to use r.mapcalc to multiply by 1e6 before running and
divide by 1e6 afterwards.

a man page would be helpful too.


thanks,
Hamish

Hint: 
to generate a HTML man page, enjoy the 'html-description' flag:

 r.grow --html-description

 r.grow2 --html-description
 r.grow2 --html-description > r.grow2.html

I just wanted to add to this wish. It would be nice if I could specify the amount
that r.grow 
would 'grow', and which features would grow. That is, rather than add 1 cell
to the perimeter of 
all features (i.e., clumps of contiguous cells), the user could specify:

1) the categories of features to grow, and
2) how many cells would be added to the perimeter of a feature
