You are certainly right here, but this does not explain why the next level of zoom should make the chart unreadable. It only takes time then for the user to click back to previous level and/or fight confusion, which will descend on many people. Probably it would be safer to disable by default the zoom at this level and let people consciously enable it, with appropriate warning on screen. But I would prefer the warning in another form, e.g. extending the big "Overzoom" message with a numerical indication of expected accuracy.

The chart itself, even overzoomed, in many respects remains as valid (or as invalid) as the nominal zoom image. The angles are kept, relative distances are kept, relative positions of objects are kept, individual characteristics of objects are kept. The chart image in most respects is still valid, and denying its presentation to the user is surprising. What is not kept is positional accuracy related to chart datum. So at overzoom level one should not plot WGS positions on the chart nor take coordinates of the cursor as indicated by the program, so preventive functionality should be probably addressed at these actions instead.

There were good suggestions in this thread to - instead of blurring the chart - make all chart features appropriately bigger, including the ship icon (and the cursor, I would add). Indeed, this would be more appropriate to the geometry of the chart, but maybe not very practical.

I think that making the marks, depths, etc. unreadable serves no real purpose, and I understand that users react negatively here.

Please note that the positional accuracy is also very doubtful at underzoom levels. At world scale level the cursor still gives many decimal digits of accuracy, and waypoints dropped at this scale can easily be far inland when one intended a seaborne location...

If overzoom is allowed at all, and it seems people want this in some situations, I see every reason to put a persistent warning on screen, but I see no reason to make the chart unreadable.

If one wanted to make a chartplotter "zoom-safe", probably other steps should be taken, but this again might create a sense of false confidence in chart quality in general. To have an island plotted 1.5 miles off its real position is common, and bigger differences are reported.

Interestingly, many of these "lies 1.5 mile WSW off charted position" cautions (CTNAREA, INFORM, but no name, so search ineffective) are not made easy to find. I feel making these warnings more apparent would contribute much more to safety...

I can reproduce your leaks on original 3.3.2330. But with the recent build, I see only a very small malloc leak, still to be fixed.

Thanks
Dave
I don't understand why the Leaked Object is always shown as "HyperlinkList" while the Responsible Frame is mostly OCPNRegion in these checks of Instruments.
Since the change of pugixml from 1.2 to 1.5 I have seen for the first time also a pugi function but not reproducible.
The screenshots are done with latest git compiling.

A) Because you have never been to the Panama Canal?
B) Because my out door screen is 6 inches and is placed 4 feet from the helm.
So make your image 6 inches wide (diagonal) and go stand 4 feet away and tell me what the depths are.
C) I don't want to use program where the makers disallow you to do something that every other program allows.

By the way, I have done Suez Canal too, which you have not, and it's exactly the same. Theres a myriad of ships, boats, markers and narrow channel. ColRegs say use ALL available nav methods and so you are just anti ColReg when you say we sholdnt use your charting program in seriously congested waters.

Where else have I done that the program makers have not done so it gives good reason to listen to me: Singaport Straits, Gibraltar Straits, the Pacific, Indian and Atlantic oceans, in fact I have done every ocean and sea that most any of your users are every going to do.
There are some that I have not done and when I do them would like to SEE the chart: Corinth Canal, Keil canal the islands of Sweeden, Denmark and Finland.

Its just not good enough to say that just me, Mark of Sea Life, can turn this 'feature' off, it should be OFF for all people, and only turn on-able if they get a letter from their local Psych professional.
People with lesser nav capabilities need to see where they are using ALL available nav systems (Read ColRegs!)

I sail in some far off and quiet waters, but also sail in some places where the shipping can be absolutly daunting. I have used OpenCpn in ways you guys would never dream to make my life safer. To remove a layer of that safety because you guys have some philosophical but inexperienced ideal is sad. Desperately sad.




Yes! All these ships are coming towards me, in convoy, and we need to pass Port to Port. To do that I need ALL nav systems, but only the ones I can TRUST have not been denuded, nerfed, dumbded down.

Re: OpenCPN Beta Version 3.3.2330 Released

Hi Dave ,

My problem:
If I'm starting the OpenCPN with old plugins, then the OpenCPN is exit. No alert just an error messages in the command line. This is not good if the user don't power user..

Advise:
OpenCPN start's running a selftest, looking the plugins version numbers and put on alert window:
,,Your plugins very old. Please delete all old plugins and refresh.''

If the alert window is closed, then running EXIT command...


---
I am Running opencpn on Slackware 14.1 and Raspberry PI.
On RPI is buttons very big, but don't problem, disabled all. (My screen size on Raspberry is 32x240...)

No. I don't give a rat's ass what you personally don't get, or would do, or prefer. Or how you think everyone else should. Or why you think every example presented to you is overstated or incorrect.

I posted that example to give the developers another idea for handling overzoom without offending every established human modal, psychological and physiological expectation.

Blurring is wrong on every single level one can imagine. It is not right on any level at all. You will not find a human interface anywhere that suddenly presents a blurred image, or a person who expects to have their viewpoint blurred suddenly (the developers here excepted, of course).

However, it is becoming clear that the developers of OCPN are now moving in directions and intentions different than those in earlier days. That is certainly the developer's prerogative, and the rest of us will just love it or leave it.

Clippy, Bob, Windows Vista, Windows 8 - lots of lessons to be learned here boys and girls...

I'll say; leave it as it is. Any conditional sorting can lead to some very complicated rules. And in the end to a possible situation where a single chart is not loaded at all.
But since you are there; It could be wise to hinder a user mistake to load the same directory twice if that's now possible. (Haven't checked.)

Can you isolate which old PlugIn is causing the exit? Remove and add them one-by-one until you find the bad one, please.

Thanks
Dave

Yes there is a problem, they render so small that they are virtually invisible. Some objects only render as a !. The tidal arrows shown in my original screen shot render about 2mm long with the overlaid ! in circle being about 5mm across hiding the underlaying arrow. This on my 15" Dell XPS laptop, Open GL on (or off).

Hiding (if that is the intention) information like this is dangerous.

Attached another shot from MaxSea showing the same area and the arrows as I believe they should be rendered. Both shots using similar Vector charts.

Re: OpenCPN Beta Version 3.3.2330 Released

Littlechay....

1. This is not new behaviour in Beta 3.3.x Exactly the same in 3.2.0.

2. If you like Maxsea better, use Maxsea. If you like O, then constructive Flyspray bug reports always get a response. Always. Piling-on in the Forum does not generally produce the expected results.

3. Especially, if you ( and others) think the O developers are intentionally hiding information, then I encourage you to look elsewhere for your charting solution.

Re: Region leaks.

I don't know why the leaks would be called Hyperlinks.

Further, I run O in linux using valgrind. No Region leaks.
I run O in Windows using Visual Leak Detector, and built in VS2010 leak tracking. No Region leaks.
OSX /usr/bin/leaks from the console shows no leaks.
OSX Instruments shows no leaks.

So, pardon me, but I suspect something is not the same for our builds.

I would like to exactly reproduce your results.
What version of XCode are you using?

Thanks
Dave
