10:40 #navit: < tauso> Hello, i've just installed the latest svn version of navit on my android device and made a look at the shipped navit.xml and noticed some OSD types I've never recognized so far:
10:40 #navit: < tauso>
10:40 #navit: < tauso>
10:40 #navit: < tauso>
10:40 #navit: < tauso> Are they new and is there a documentation somewhere in the wiki?

18:07 #navit: < tauso> Hello, does the "Demo" vehicle work in the current svn version? For me it crashes everytime i try to set a route (set as position an set a destination)
18:09 #navit: < tauso> ok, have found the problem: osd type="compass" is enabled it crashes.
18:19 #navit: <@KaZeR> hi tauso
18:19 #navit: < tauso> hi
18:20 #navit: <@KaZeR> weird. can you please share a backtrace ?
18:24 #navit: < tauso> hm, debug log is empty? what do i have to add in the navit.xml?
18:26 #navit: <@KaZeR> you won't really see it in the debug log, rather in the console output in case of a segfault. do you have gdb installed ?
18:27 #navit: < tauso> http://pastebin.com/jvBPgjij
18:28 #navit: < tauso> seems so:
18:28 #navit: < tauso> ii gdb 7.7-0ubuntu3.1 amd64 GNU Debugger
18:29 #navit: <@KaZeR> yeah the BT seems complete. what is your graphic card? on my laptop, with an intel card, sometimes a bug is triggered that completely kills my X session. but that's a bug in the driver i believe

18:30 #navit: <@KaZeR> do you have issues with other OSD components or only the compass ? what other OSDs do you have enabled ?
18:30 #navit: <@KaZeR> either there is a bug in the rendering, or maybe the text which the compass is trying to render is garbage and it could lead to this crash
18:30 #navit: < tauso> its an ATI HD5670 with the proprietary fglrx driver

18:31 #navit: < tauso> i've only used the shipped navit.xml and enabled compass
18:32 #navit: < tauso> navigation_next_turn works
18:33 #navit: < tauso> i've enabled the other navigation types too and (without compass) it doesn't crash but it also doesn't show anything other than the next turn image (arrow...)
18:33 #navit: < tauso> map and route rendering seems ok, too
18:33 #navit: <@KaZeR> odd
18:34 #navit: <@KaZeR> actually the BT shows that the text is not garbage : text=0x16fbec0 "1400m"
18:35 #navit: < tauso> than maybe i've forget something to add in the xml. do I need a width attribute for these types?
18:35 #navit: < tauso> actually, i only wanted to try these (for me) new OSD types, as there is nothing about them in the wiki
18:37 #navit: < tauso> for me, the compass bug is not a big deal, cause I never use it in my "real" navit.xml on my android device.
18:37 #navit: <@KaZeR> i just tried on my laptop, osd compass + gui_internal + gtk_drawing area + demo vehicle, does not crash, compass works as expected
18:38 #navit: <@KaZeR> graphics/gtk_drawing_area/graphics_gtk_drawing_area.c:421 is a blank line for me. what do you have exactly at this position in the code ?
18:39 #navit: <@KaZeR> what do you call the new OSD types ?
18:43 #navit: < tauso> "navigation_distance_to_target", "navigation_distance_to_target" and "navigation" as types are new - for me. I've never looked at the shipped navit.xml for a long time.
18:43 #navit: < tauso> "navigation_distance_to_next"
18:45 #navit: <@KaZeR> oh ok. the navigation item is quite powerful as you can access a lot of sub-items
18:45 #navit: <@KaZeR> ${navigation.item[1].length[named]} for example
18:45 #navit: < tauso> ok, that I've used for a long time
18:45 #navit: <@KaZeR> yeah this one is quite handy :)
18:46 #navit: < tauso> but i think in my xml it is a type"text"
18:46 #navit: < tauso> 421 if (!bg->c.a)
18:46 #navit: < tauso> 422 bg=NULL;
18:48 #navit: < tauso> and i thought eventually type="navigation_distance_to_next" will replace something like ${navigation.item[1].length[named]}
18:50 #navit: <@KaZeR> have to go afk
18:50 #navit: <@KaZeR> i think this bug might be triggered by a recent change
18:50 #navit: < tauso> thanks for debugging
18:50 #navit: < tauso> bye
18:50 #navit: <@KaZeR> if you want to dig, have a look at cp15's commit in the two last weeks ( there aren't so many of them
18:51 #navit: < tauso> i think i've read something about background color
18:51 #navit: <@KaZeR> or try r5792 that's the one i have here
18:51 #navit: < tauso> and bg sounds like it
18:51 #navit: <@KaZeR> (it's from before cp15's last change)
18:51 #navit: <@KaZeR> i'll be back in ~2 h

20:14 #navit: < tryagain> tauso i guess 421 if (!bg->c.a) should be 421 if (bg && !bg->c.a)
20:20 #navit: < tryagain> tauso svn revision 5799 has the fix

22:05 #navit: < tauso> For me the osd types i mentioned earlier (which are in the shipped navit.xml) don't work. And when I grep for "navigation_distance" over the whole navit code, i can only find it in the navit.xml file and not in the "/navit/osd/core/osd_core.c"
22:08 #navit: <@KaZeR> the example in the xml might be a leftover indeed. does ${navigation.item[1].length[named]} fits your need ? iirc, the point was that switching to the navigation item would allow even more configuration when the navigation_distance was quite static
22:08 #navit: <@KaZeR> tauso, can you confirm that tryagain's fix fixed your issue ?
22:10 #navit: < tauso> yes, as i mentioned earlier, I have used this syntax for a long time and i thought the navigation types where a just a new form of that syntax, thats what confused me.
22:10 #navit: < tauso> Yes the fix works.
22:12 #navit: < tauso> but i didn't check out the new svn version, but rather edited the .c file and did a new "make"
22:12 #navit: <@KaZeR> yeah that'll do the job
22:12 #navit: < tauso> should be the same, as he only changed this :-D
22:16 #navit: < tauso> KaZeR could you explain me Commit [r5796]? whats the difference between attribute "text_background" and the old "background_color"?
22:22 #navit: <@KaZeR> i think that the difference is to be able to cast some kind of shadow behind your text, where the background color would put a solid background color for the whole text box
22:22 #navit: <@KaZeR> somehow like this : http://www.divine-project.com/wp-content/uploads/post_images/simple-shadow.jpg
22:22 #navit: <@KaZeR> and hence enhance readability over any kind of background
22:29 #navit: < tauso> that sounds good, but it isn't implemented yet, as only the header file is changed in the commit, am i right?
