Ocpn-Draw and Boundary

[jongough]

Hubert,
Patch 504 fixes the properties dialog not keeping your changes. The global settings are available through 'Options/Plugins/ocpn_draw_pi/preferences' . I have put up a linux executable of 504 on GitHub.

Please continue to play!

And preferences are really global preferences - correct.

You are absolutely right that we should now encourage to use the existing tools in order to learn about the usage and the UI.
Can you put the .503 executables on GitHub?

Great job

Hubert

Hi,
Patch 506 fixes some issues with path properties and saving OD objects created after an EBL.

Give it a try, its working very nicely. Requires Opencpn 4.1.818 9-1-2015 version (uploaded too).

Installed it under 4.1.602, the official beta and seems to work.
So even easier to try it out. Jon needs feedback.

Hi
I'm using WinXP and therefor forced to VC++2010. The "round" method seems not implemented there but gives an error.
Instead I successfully tried "floor". I'm not fully aware of the differences between the two methods, but please consider to use something else than "round" as long we shall support XP and VC2010

Basically explained:
 
- ROUND rounds down or up, e.g. 1.3 => 1 & 1.5 => 2 (+ROUND(A1,0)
- FLOOR rounds always down, e.g. 1.61 => 1.6 (=FLOOR(A1,0.1)
- CEILING rounds always up, eg. 1.61 => 1.7 (=CEILING(A1,0.1)

hello,

A project has been created in Tracker/Flyspray, you will now be able to deposit bugs and request.

I don't have access to my windows compile environment at the moment so cannot do anything with the round function. Is it possible to determine that vs2010 is being used in an #IFDEF statement? If so could we put in the round function for vs by enclosing the following code in an #ifdef?

double round(double num) {
    return (num > 0.0) ? floor(num + 0.5) : ceil(num - 0.5);
}

Jon...
You can use exactly the same as we already have in https://github.com/OpenCPN/OpenCPN/b...Dialog.cpp#L59
Or use wxRound()...

Håka,
I have applied the fix suggested by Pavel to the TextPoint.cpp code. It is patch 507. Can you give it a try and see if it works.

Ta Jon

[Hakan]

Jon..
Works very fine.
Thanks/
Håkan

[Hakan]

Jon..
And many thanks for this plugin. I've now used it to mark a new mussel breeding where I use to sail. Very nice to have now when the darkness arrive and its unlit. It's not so nice to be entangled in drums and rope.

EBL: possibility of range and bearing from EBL-point TO own ship?


What follows was posted earlier (and by mistake) in the "OpenCPN Beta Windows Plugins" thread. Per Rick's advice I copy it now under this thread (I don't know of any other method to transfer earlier posts to another thread).

-----***----

EBL: possibility of range and bearing from EBL-point TO own ship?

OpenCPN just gets better and better and the EBL in the Draw PI is a great feature. It gives the position of an EBL-point (other ships/objects) in relation to your own position. But I'm wondering.. is it possible (and useful) to add an option to turn it the other way round? I mean: to give my range and bearing FROM that other ship/object? (e.g. "This is Seanymph, my position bearing 123 degrees from buoy X, distance 3 miles"). After all, isn't that's (one of) the way(s) we are supposed to communicate our position?

Of course I can use Measure to give me the information but that won't update automatically as I move on.

Am I missing something?

Roel

Rick, in that other thread you wrote "Can you help write the manual for the plugin?". I'm not sure what you mean with "the manual for the plugin" but if it has to do with programming I'm absolutely useless. The only thing I might be able to do is to translate text from English into Dutch but I doubt that's what the world is waiting for. That is apart from the fact that some people say I'm very capable of finding a problem to a solution....

Roel

[rgleason]

Roel, Your english is excellent better than my dutch. No programming needed. I just need someone to review and augment what I write about using the ocpn_draw plugin. Are you game? It is to help new users and answer questions. Look at the documentation on opencpn.org for weatherfax, weather_routing, chartdwnldr and celestial navigation. These are examples I've been involved in.

[Roel Smidt]

Hi Rick,

I'm very willing to help where possible. Just tell me what it is you want me to do and I'll give it my best shot. But as I said, I'm absolutely no programmer and my knowledge of the Android/Linux language is very, very basic

FYI, I'm toying with OpenCPN at home on my Desktop (Windows7) and on board with a Samsung GT-S7710 smrtphone (Android 4.1.2) and Samsung 7.7 Tablet (ICS). And I somehow got O up & running on a new toy (Raspberry Pi2 that maybe one day will evolve into my onboard computersystem) ...
