Organizing Nav Objects into Layers

[sinbad7]

Nohal..

Regarding the transparent markers - what's the problem with making a transparent XPM and placing it in the UserIcons subfolder as shown on the attached screenshot? Or did I understand wrong what you mean?

And where do I find this UserIcons subfolder?

Your #9... I downloaded and installed your version of opencpn.exe but I can see no extra items? No layers,, no extra icons...

Pjotr,
thanks for the compliments
More files in a layer seems like a good idea and a viable use case to me, which is not hard to do. Furthermore I would keep it as simple as possible - as far as we will be limited with the navobject/gpx stuff the solution will not be perfect anyway...
In the longer term KML | OGC(R) looks like a beast we should look at for this stuff. It could kill quite a few flies with a single stroke...

You have to create it and place your icons there. Follow the instructions at the beginning of Routes and Marks | Official OpenCPN Homepage
Your icons will appear at the end of the list. One attached for testing, just remove the .doc and place it to the folder you create according to the manual.

Your #9... I downloaded and installed your version of opencpn.exe but I can see no extra items? No layers,, no extra icons...

There are no extra icons, just a new tab in route manager. Are you sure you are running the right exe?
Just to make sure - it is not an installation package, just a replacement application executable. And it does not contain the import fix.

I've set up the UserIcons folder and downloaded a few markers in .xpm format
and all is selectable from the Mark properties box.

However. when I made up a new icon as a transparent .gif in GIMP2 and saved it as a .xpm file it did not show up in my properties box? Not familar with the .xpm format but the new icon works as a transparent .gif and it is duly saved as a .xpm ??

Appreciate your advice.

Tore,
could you post one of the problematic XPM files for examination? Don't have Gimp on my netbook to try to reproduce your workflow, but will have time to do some not physically intensive stuff as the afternoons are bit too warm for me here in Iguazu

I'm working with Gentoo and a 2.6.37 kernel

Thanks for trying!
I understand your compiler has a problem with the lines

                        int i = c.Find(',');
                        if (i != wxNOT_FOUND) c.Remove(i);

Visual Studio accepts this, and the wxWidgets docs I have do not specify any constructors for wxChar constants, so I was just guessing...

I think you have 2 options:

1. try c.Find(wxT(','));
2. comment out both lines, then you will get e.g. "Dover, England" instead of "Dover" as column heading. Not a big issue.

Good luck and thanks again.

@Pavel...
Thanks for helping with layers teething patches...

I think the Import/Export buttons can indeed be disabled for Layers tab, to avoid possible confusion. Otherwise, I still believe a layer should be statically defined as a single file or directory. It should be completely defined outside of OpenCPN, rather than built interactively.

At this stage the easiest solution, otherwise the GUI will end up full of buttons nobody understands. I would probably go with a folder for each layer. A little bit more to implement but quite understandable and transparent for the user IMHO.

Just re-booting OpenCPN displayed all my new nav. marks in the Mark properties box.
I can see no extra tag/label in the route manager?

When I've completed all the transparent nav. marks I'll upload them here.

Is there any way to lock the nav marks so they are not accidentally removed?
Presently they are too easy to move.

nohal/PjotrC..

Here is a list of 25 navigation objects to be added to your Mark properties box under the sub-directory of 'UserIcons'.

Sinbad7...

Thanks for the icons, they look great... but... perhaps it would be possible to center the images on the right spot in the icon? This problem affects also the icons built into the release OpenCPN. Unfortunately, this is not always in the middle of the picture

Layers is the way to protect permanent marks on charts. The executable nohal posted from my patch does work for me... thanks again, Pavel.

PjotrC..

Yes I noticed the same,particularly with icon # 3-9 and 10
The centre is of course the centre of the 'invisible' frame.
Not sure how to change this.
The small white dot at the bottom should indicate the icon's geo loc.

I am using the patch you mention (Vista) but there is no indication of any
extra label in the Route manager?

Tore

[nohal]

XPM format supports including the hotspot coordinates in the image, so it should be pretty painless to include such a functionality... If it's not already there - haven't looked at the code yet.

Pavel

Here are the updated IALA sea markers for OpenCpn as per my #25.
Place them in a sub-directory of OpenCPN called 'UserIcons'.

The icons are normally move by the white dot at the bottom but some of the larger icons are moved by their imaginary centres of their background tiles.Perhaps nohal can fix this for us?

Attached is a patch supplementary to the original release candidate + 2 teething patches from nohal.

It includes the following changes:

- import/export buttons are disabled on the RM layers tab
- manual Load layer builds a single layer from all files selected in the dialog
- the name of the layer is assumed from the filename for single files, from directory name - for multiple file import
- initial loading occurs from /layers directory as follows:
- individual .gpx files create a separate layer per file
- any subdirectory present will create a layer from all of its .gpx contents

A small modofication is also included for drawing waypoints - still does not solve RM toggling visibility for tracks, but works well in layers.

I am still hunting a crash occuring sometimes on the very first call to RM, which never occurs on a fresh opencpn.ini :-(
