Ocpn-Draw and Boundary

this idea:

In this same context one of the things we are looking for is the ability to add depth track data to charts on our own, without going through an online service. The dream system would entail surveying in the dinghy, with the position and depth data fed directly to the mothership.

What about to be able to "inject" or "import" drawn objects into the plug-in?
Or export those in order to share?
In SignalK format perhaps?

Just dreaming....

Jon, tomorrow I be ashore and able to access my laptop with VS 2013 and Ocpn 4.1.602.

Hi,
I have just put up the 0.4.0420 patch windows install file into git. This version does not fill boundaries on windows under opengl when there are more than four points. Still trying to figure that one out.

Hi,
There is a windows installable in the git repository, you will find it in the 'pre-release' 0420 tag.

Installed and works as announced.

There is something strange with the backgrounds - will not cover the complete text (depending on the font) on the right edge and the rounded corners do not adjust well (radius?)

This all with OpenGL enabled. As you already stated the text example for the default font does not show up at the font selector but once gone through the cycle it's allright.

Pretty good

Modifying the font afterwards does not bring up the selected font. The old one stays and somehow the background gets touched. When switching back to the original font it's ok.

What is the reference point for placing the text? Botton and Top I would expect "horizontal centered" and in case of Left/Right "vertically centered". Another option for cartographers?

[jongough]

Hi,
The text top left corner is the reference point. I only provided 4 locations to make the initial implementation easier, so you have:

• Top: which puts the text over the top of the point aligned to the left edge of the icon with the bottom just clear of the icon
• Bottom: which puts the top edge just underneath the point aligned to the left edge of the icon. If you displace the point name the text should drop enough to show it
• Left: which puts the top edge aligned with the top of the icon, the text to the left of the icon with the right hand end of the text box just clear of the icon
• Right: which puts the top edge aligned with the top of the icon, the left hand edge of the text just clear of the right hand side of the icon

The amount the box edge is offset is controlled by 8 settings in the opencpn ini/conf file. You will find them called:
DefaultTextTopOffsetX, DefaultTextTopOffsetY
DefaultTextBottomOffsetX, DefaultTextBottomOffsetY
DefaultTextRightOffsetX, DefaultTextRightOffsetY
DefaultTextLeftOffsetX, DefaultTextLeftOffsetY

I was not sure if I should make them adjustable on the properties panel or not.

I will look at adding horizontal and vertically centred as an option.

Changing the font in the properties box does not apply the font until the OK button is pressed on the properties box. The word 'Example' should change to show you the font selected.

I will look and see if I can make the background box a little bigger. The information for the size of the box is obtained from the system depending on the font used, so I may have to make that an attribute of either the font (may be difficult) or of the point itself.

Jon,

the examples are after pressing ok
In the first case - this is a text marker from a former version - does not happen anything trying to change to the fancy font shown from the settings and in the second case just the size of the ox changes but nor the font of the text - tried several different fonts here.

Not sure what is going on here. If I display the font dialog and select a different font and press OK in the font dialog, the 'Example' text updates (sometimes badly, need to fix this). The text for the point stays the same. If I then press OK in the properties dialog the font for the text updates.

Example on my windows 7 system (running under latest virtualbox with 3D acceleration turned on to help with opengl debugging).

I will have a further look as soon as I can to see if I can find out what is happening.

Hi,
I have put up the first version of the plugin that can handle JSON messages. Currently this is limited to finding a boundary that has a point (Lat/Lon) within it and responding to the originator (with a JSON message) saying if the point is in a boundary and supplying the GUID of the boundary if found. This is the very early version of this and is still subject to change. If anyone is developing a plugin and would like to try it out let me know.

First with OpenGL ON - wrongly applied , second OFF as described by you OK (Win 8.1)

I have found the text is not being updated properly in opengl. I will look into it further tomorrow.

[bcn]

Jon,

another idea: to change the icons of a boundary path you will have to go one-by-one. What about "apply to all"?

Hubert

[jongough]

Hubert,
I have put up a new version in git that fixes the text display and allows you to select whether to change all boundary icons when you change one. Also there are now a few more locations for the text for a textpoint, i.e. centre top, centre bottom and centre. I have put up a windows installer package. This is now patch 0450.

Jon,

works fine and you have as well solved the fonts issue in OpenGL, dont you?
One observation: the background on the right side of the text seems to go a bit too wide always as the radius ot the corners is bigger.

With the Json stuff I'm thinking how to test but this will take some time.

What's next? EBL/VRM?

Hubert
