Hi,
I found out what the Color by attribute tool (the big L) does. It seems to
delete the per feature color attributes so that the style defined for the whole
layer is applied. I think that the name of the tool is not the best possible.
Could it rather be “Use layer color” of “Default color” or something like that?

Hi,
Please remember also that JML has support in GDAL and it is aware of R_G_B
http://www.gdal.org/drv_jml.html. I wonder it new Color chooser now requires
that both R_G_B and COLOR exist. It is rather simple for the external tools to
write the RGB values into R_G_B field while they probably do not know what
color index number they should use.

Peppe,
In Dxf driver, I create a default schema with a COLOR attribute which is the
name used in dxf to set features color.
But the role of this attribute is very similar to the one added in Color
Chooser plugin (R_G_B)
I would have no objection to change one of them (store color information from
dxf into R_G_B attribute or rename
R_G_B to COLOR) if it could simplify things.
Maybe R_G_B has less chance to collide to another user attribute...

Hi Jukka
Color chooser if formed by two icons on the toolbar:
(a) one square icon that is colored by the "actual color". If the user select a
feature and click on this icon, the geometry is colored
(b) the menu of th tools (Color menu, pick etc)
>There is a new Color picker tool in the Set color toolbox.
It helps in this situation: 1) you have an already colorized feature (by using
(a) tool), 2) you want to resume the color but 3) button (a) shows a different
color.
Using Color picked on the feature resumes the color value from the feature and
re-colorize the (a) icon

It is a side effect as I used lower left corner to visualized the value of the
color... and lower left corner box text can be copied into the clipboard...
>Color by attribute tool
If you have colorized a feature using a) and you want to restore the original
color /style set by attrubute or else, colo by attribute tool reset the
original style (delating "COLOR" and "R_G_B" attribute of the feature
Color chooser seems to be "oversized" comparing to what was the original idea
of SkyJUMP (to color few features to identify between others). I use this tool
to work together with CAD files, if I export to dxf a set of feature with
"COLOR" attributes, those area automatically trasformed into DXF COLOR values

Hi,
There is a new Color picker tool in the Set color toolbox. It show the index
number of the color and shows RGB values in the lower left corner, in a box
that claims that the value can be copied into clipboard. For me it seems that
copy-paste does not work. Is there some other purpose for the tool? Another
question is about the Color by attribute tool. What it really does and how
should I use it?
