Odometer OSD

[tegzed]

Hello,

I have created a simple odometer OSD module for navit that displays the distance since initial start or reset (see attached patch). The usage is similar to stopwatch OSD (see ticket ##643). Single click starts/pauses counting, double click resets the odometer. If you find it useful please check it in to svn.

One note about the configuration: You will need an osd tag with type attribute set to "odometer" in your navit.xml. My entry looks like this:

<osd enabled="yes" type="odometer" w="150" h="40"  x="30" y="250"   font_size="500" />

I like your patch, David.

Three things, from a usability standpoint.

1) Before the odometer is active, leave the text as green. 2) When the odometer is active, please have the text changed to white. 3) When the odometer is paused, please have the text changed to orange or red.

It can be very hard for the user to know what state the odometer is in.

Hello Number6,

Thanks for your suggestion, I'll implement it soon, possibly I'll find a way to display the average speed of the measured intervals optionally also. Maybe I will use a format string substitution similar to osd text. I will also give colors to stopwatch osd (#643) accordingly.

Patch to add odometer osd

[number6]

It should be used as follows:

<osd enabled="yes" type="odometer" w="350" h="40" x="30" y="300" font_size="450" label="Dst:${distance} ; Spd:${avg_spd}" />

Distance== Total distance Travelled avg_spd == Average speed.

This feature was added in ​Revision 3557

Keep up the good work, David.

Hi David,

thank you for these cool new features (odometer and stopwatch)! I love them and have to pay attention to keep driving not playing :-)

When using a blue background like 'background_color="#646FC3cc"' I can't distinguish 'orange' from 'white' very well. Thus I suggest the following patch, which makes the idle text color selectable by the user. The patch holds for the odometer and the stopwatch. The idle text color is selected by the 'text_color' arg via navit.xml.

I use the odometer and the stopwatch as follows:

<osd enabled="yes" type="odometer" text_color="#00ffffff" w="350" h="20" x="200" y="0" font_size="300" background_color="#646FC3cc" label="Dst:${distance} ; Spd:${avg_spd}" />
<osd enabled="yes" type="stopwatch" text_color="#00ffffff" w="100" h="20"  x="550" y="0" font_size="300" background_color="#646FC3cc" />

@admin: <CR>'s from DOS appeared in osd_core.c. My 'svn diff' ignores the eol-style, because I removed some <CR>'s in my local copy.

make the idle text color user selectable with 'text_color'

[tegzed]

Thanks Chr! Good idea, maybe it worth implementing it in stopwatch(#643) also and augmenting the wiki so the users know how to use this.

Hi Chr,

I like your idea. The user should be able to override the standard white and orange colour by using flags in nativ.xml

Can you create a diff that will do both the Odometer and stopwatch?

Regards,

Nick

Hi,

@David, @Nick: I expect the supplied attachment 'osd_core.c.patch' already to contain the diff for both, the odometer and the stopwatch. Am I wrong?

The patch (diff) has been generated with the following command:

LC_ALL=C svn diff -x --ignore-eol-style  navit/osd/core/osd_core.c >../osd_core.c.patch

Do you ask for something else?

After reading ​http://wiki.navit-project.org/index.php/OSD#Color I think we should first make a good choice for the attributes. Odometer and stopwatch should use the attributes in a consistent way with the other types. I like the following idea. What is now hardcoded 'white' should become selectable with 'text_color' and what is now 'orange' should get a new attribute may be 'idle_color'.

What do you think?

Bye, Christian

Hi,

here comes an alternative patch for the color selection of 'odometer' and 'stopwatch' as suggested before, 'color.patch2'. It can be used in the following way:

<osd enabled="yes" type="odometer" idle_color="#00ff00" text_color="#ffffff" w="350" h="20" x="200" y="0" font_size="300" background_color="#646FC3cc" label="Dst:${distance} ; Spd:${avg_spd}" />
<osd enabled="yes" type="stopwatch" idle_color="#00ff00" text_color="#ffffff" w="100" h="20"  x="550" y="0" font_size="300" background_color="#646FC3cc" />

'text_color' defaults to 'white' and 'idle_color' defaults to 'orange'.

Regards, Christian

Added in ​Revision 3568, thanks Chr!
