Hi,
trying "volors" (i.e., gui_modules/colorrules.py) I found small bug
and
got a few ideas to improve this promising dialog.
Please see attached screenshot as I found it easier to indicate the
ideas there.
Those which aren't easy to fix I'll submit later as tickets.
thanks
Markus
Hi Markus,
Interesting. The bug you've found is not the one you think you found ;-)
Both menu items "color rules" and "color tables" under vector->manage
colors are bringing up the same color rules module from wxGUI.
Instead, "color tables" should be bringing up the interface for the
new v.colors GRASS module. I suspect it's just a typo in the menu
string.
The vector color rules module does not do what you are assuming it
does. That is, it does not automatically spread a color gradient
between a max and min value. What it does is allow you to custom set
colors to individual values or ranges of values, and store these
colors in the GRASSRGB color column. The add column button may not be
too hard to implement (automatically refreshing the column list may be
the biggest headache). The other suggestions don't match this module.
This module was written before v.colors and has different functionality.
The functions you thought were in the color rules wxGUI module are
actualy in the v.colors GRASS module. The "color tables" menu option
ought to call this module. It automatically sets max and min, but also
allows the user to set custom max/min. It then lets you pick a color
table and automatically assign the color gradients to the vector values.
I'll try to get this fixed when I get to my office today. Hopefully
it's a simple typo.
Michael
