Re: [GRASS5] Suggestions for gui discussion

Michael Barton
Wolf,

I agree that the old interactive xterm interface (including i.points,
d.zoom, and others) needs to be updated. These interactive, mouse intensive
activities would probably benefit most by a new, better integrated GUI.

I'm a little puzzled by your wish for functionality, however. Currently,
GRASS (i.points) does open a pair of side-by-side windows that zoom and pan
synchronously, and permit you to click on the map to be georeferenced in one
window and a corresponding georeferenced point in the other. Alternatively,
you can enter the coordinates for a point to be georeferenced. It also
allows you to check the accuracy of your georeferencing and manage the GCP's
that you use to some degree.

Maybe because your (Cygwin?) system drags so much because of the mouse
polling bug, you've never gotten that far in i.points?

That's 4 to keep the initial discussion on the main developer's list and one
against it. I think it's important to have broader input. So I'll keep it
here for now.

That is true. The good thing is that it still works.

I does? I only got one window where I could zoom and pan. And don't get
me wrong. I do think that the option of allowing one to enter
coordinates by hand is a very important feature that should not be
removed. I would for sure use it if I would for example have a set of
GPS coordinates and an aerial photo to rectify. This time I had a
scanned GT map to rectify to a raster map. It is possible that I simply
didn't use i.points correctly...

The strange thing is that the system doesn't really drag, I'm running on
Debian Linux, but the CPU goes crazy and the fan too. (I really hate the
FAN).
