Re: [Paparazzi-devel] Change waypoint name color

[Gautier Hattenberger]

Hi,

Finally I found why the green color is not as green as before: the definition of "green" is different for X11 and W3C.
http://en.wikipedia.org/wiki/X11_color_names
http://www.htmlcolorname.com/00ff00.html
http://www.htmlcolorname.com/008000.html

So for people with "dark" green, if the color is set to "lime" the resulting color is the expected one.

The problem is that I don't know how to tell to gtk/gdk/lablgtk(?) to use the X11 color map rather than the W3C. Any one with a good idea ?

Possible solutions:
- replace "green" with "lime" if it works for people having X11 colormap
- replace "green" with "green1" if it works for everyone
- replace "green" with "#00FF00" that is not user-friendly but should work

Concerning Piotr solution, it would be nice to avoid adding more elements to the canvas, but maybe it doesn't make a big difference in the end.

The bright green is correct on mine ubuntu but it steel difficult to read.
I like the modification proposed by Esden but i changed the white by yellow color.

Next week i will test in the field.

Thank you Luis,

So in the end, it looks like the real problem is a bit different: the green color is not the expected one. I have the same issue but I thought it was due to an ubuntu upgrade since it doesn't do the same on all the computers of my lab.
I already tried to find the source of the issue without sucess. If a set by hand the RGBA value for the green color a get the expected one, but if I use the string name "green" it doesn't. I can't tell if it is a gtk or lablgtk (the gtk-ocaml glue) issue.
So if anyone have an idea where to start, that would be welcome.

Hi Luis,

Can you tell me what is the exact "green" color that you have: is it a bright green like this http://paparazzi.enac.fr/wiki/File:Gcs.jpg or is it something darker ?

Since latest ubuntu versions (kubuntu actually) I have some weird issue with the green which is not that green...

Thanks

Gautier

Glad it works for you. I did a very quick modification to the gcs code to add contrast outlines to the GCS text labels. 

Let me know what you think:

https://github.com/esden/paparazzi/tree/gcs_label_outlines

I very likely missed something as it is a 15min hack. I will improve it if you say it is a useful improvement.

Cheers,

Piotr

Hi Luis,

As far as I can tell there is no global option to change the label color. You have to go and edit line 69 in sw/lib/ocaml/mapWaypoints.ml and change the FILL_COLOR attribute. I think a much better solution would be to find a way of adding a dark outline to the labels, by introducing for example a second label under the first one that is 2 points bigger or so in a different color. As the Gnocanvas.text object does not support the OUTLINE_COLOR attribute as far as I can tell.

Cheers,

Piotr
