Håkan,

We are talking about functionality implemented in C++ code here. Why would it not be "feasible" to break it out into a function that can be used independently for both operations? I mean unless the code is such a mess that the functionality can't even be defined. (Oh! Did I just answer my own question?)

As for the advantage of splitting these two operations -- it is just good software design and implementation to not restrict the users ability to control how the program operates. Of course, you can always wait for the inevitable bug report when a user finds a conflict between these operations.

Re: OCPN Beta 4.8.1 PreAlpha

Hello...

And the winner is:

"Chart Rotation Averaging Time".

It conveys (to me, at least), what the code is doing, and what the expected effect on screen might be.

Thanks for all the input
Dave

Rick..
Very good. May I suggest some more info? See my Italic text below. Pls edit to pure English.
Håkan

Quote:
Chart Rotation Averaging Time (New Title from version 4.8.1) This relates to how often the entire displayed chart is updated when Look Ahead and/or Course-Up mode are activated. The Own Ship and AIS icons are still updated every second. The default value is 15 seconds. A “zero” value is allowed! The default up mode is North-up. It's easy to switch between North-Up and Course-Up modes through the right-click menu or the GPS status icon https://opencpn.org/wiki/dokuwiki/do...ps_status_icon.

Re: OCPN Beta 4.8.1 PreAlpha

Hakan, Thanks much better See Chart Display

and FAQ "Using "Follow Ship Offset" and "Look Ahead" and "North up" Modes, the chart jumps too much."

--Any suggestions here?

Re: OCPN Beta 4.8.1 PreAlpha

Hakan...
You may want to install liblzma-dev (this one actually was there for a long time, but maybe broken on ARM and now fixed. If liblzma is detected, support for compressing your charts on disk to save space is enabled.)
and libexif-dev (Adds some features we currently don't need to the SVG parser, but as the upstream implemented them and I was merging the updates...)

May I humbly submit "Chart rotation smoothing" for consideration?
Less technical and more informative of _what_ it does instead of _how_.

Re: OCPN Beta 4.8.1 PreAlpha

If the machine can support it, if the chart is rotated and redisplayed at 25 frames a second with sufficient filtering of the heading, it could provide a smooth usable display for course up, and would allow look ahead mode.

I agree that we need to do something about the look ahead mode. Probably the easiest is to not move the chart at all until the ship exits a rectangle set around it which is reset when the chart does move.

Sean, how's your firewood holding up? We were concerned. Where did you get the internet!

Re: OCPN Beta 4.8.1 PreAlpha

Dave, Pavel, I don't know if you noticed it, but tracker seems to be misbehaving. Lots of extraneous text, or is just my browser (I've cleared the cache twice.)?

PS: I wonder if this is due to the upgrade to PHP 5.6 for the User Documentation?
If so, perhaps we need to run a different version on Tracker?

Re: OCPN Beta 4.8.1 PreAlpha

Rick..
Yes, you already posted it elsewhere (and as usually there is absolutely no need to do it twice, we do listen to you).
Seems like a PHP upgrade on the server changed the config and "& ~E_STRICT" has to be added to the error_reporting line in php.ini.
Nothing you or me can do about it.

Pavel
