Is this another weird NON-Polar projection?
00_UKMet_Boden+100-Polar.gif

Opencpn 3.2 is not turned on. (Sorry I meant OpenGL, it was getting late I guess.)

I am going to have to try this again tomorrow morning with Debug version.

After renaming my opencpn-git file, running a git clone to create a clean opencpn-git and debug environment, using Debug I found that this file had some break lines similar to some other polars tested.

In the popup window it was bitmap.cpp Line 802

In the call stack it was
> wxbase28ud_vc_custom.dll!wxTrap() Line 678 C++
wxmsw28ud_core_vc_custom.dll!wxGDIImage::IsOk() Line 158 + 0x11 bytes C++

I said I would try it with Debug.

I found that the 00_UMET... file has an error "bitmap.cpp [802] similar to others files that have problems...

error bitmap.cpp [802]

These posts found same error.

See call stack errors in post above please.

It must be a weird projection because I can't get it to have straight lat / long after transform.

This is the call stack.

Regarding the AUS & SA wx maps. It looks like the "Lambert’s conformal conic projection", could be worth trying.

Thomas

Good idea. I think this is probably the case, I will look into the conformal conic projection and should eventually support it.

I suspect that the image has not been initialized.

Yes it was not in the case of the wav file. I think this is a condition where it gets updated before this is hit on some platforms. Anyway it should be fixed now in git, and also phasing should work.

Lars

Yes good idea, I will do this for the next version.

As for color coding the gui, it should be possible. Displaying arrows pointing at the pole is a good idea eventually can be implemented.

[rgleason]

Thanks Sean for advising about possibility of color. Here is a rework of the future interface idea, for thought/discussion.

Sean, I was thinking about your sailing your Bristol to New Zealand. What year is Alexandra? That's a long way from Bristol, RI. Where did you sail from and when did you start your journey? Someday I hope to get back the NZ, it was about 10 years ago..it was a very long flight! Sailing is low carbon. What a great place.

[ChuckSK]

There is another Assert error in weatherfaxdialog.cpp:438.

[rgleason]

Seems to be working better on valid images in mercator. The first screen after selecting used to have transparency areas in the lower area. This situation is not occurring on Noaa mercator faxes now, but does occur on other types of faxes.

Tried to highlight a blank coordinate settings and pick "remove". Instant error see below, but it seemed like coord saving was working better, sometimes I would pick a file that had been loaded in that session, and the settings were already in place.

I should probably go back in and edit out those blank lines again in the settings file Config file location: C:\ProgramData\opencpn\opencpn.ini !! Which I will do now.

[rgleason]

The problem appears to be a badly formed Names field?
Which seems to have multiple colons, and also a coordinate set called POLAR (in capitals) that does not exist. I also have "Polars" so maybe the code is not registering/checking capitals. I am going to take the red items out and see what happens (there were blank records showing for each of the red colons.

Restarted Opencpn in Debug mode after changing opencpn.ini.
Loaded a new image. The blank lines were gone.

• Directly after loading the file, you can see the "Browse file directory" has not closed yet.
• Also there are some transparency artifacts in the lower part of the window.

Skew and Phasing on mercator, these features work, it takes a little while to process them but it works. It would be useful to have a very small reset for both skew and phasing. Hit next to next coord window.

The second screen shot below shows the Coord saving dropdown open with the list of coordinate settings.

When I type in a new Coordinate Name, say '96hr500mb' it seems to save the name when I hit Apply, then I go through and complete and "finish" the fax.

Then I open another fax, get to the coord setttings and try to select/apply that same set of Coords '96hr500mb' the coordinates are correct, but the name '96hr500mb' disappears from the window. Shouldn't it stay there unless I change something, in which case it should get another New__Coord_Name_X?

Maybe these screen shots will help explain.
I was wondering if we need a "Save" coords but I think that gets done when we hit "Apply"

[rgleason]

New image loaded. Blanks appearing in Set Coords dropdown though. Don't know why.

Also, on the first screen loaded after selecting an image, where there are transparency issues, I notice that if I click in that area, the skew and phase sliders appear and can be operated.

This has all been done with OPENGL turned on.

I am going to avoid exotic polars unless you ask that I test them.

[rgleason]

Using Polar file 13021903-Polar.png attached

1. Trying to get it to work, with Lats positive it comes up with this message, when they are negative (-70 and -20 or -30 for example the image renders but is screwy. see screen shot


2. Popup, bitmap.cpp [802] error again. see screen shot.

I guess I need to find a GOOD Polar file to test with.

[rgleason]

Tried IDY00030.201302181800-Polar.png its weird too.
another bitmap.cpp 802 assert error.

[rgleason]

Tried ma-sy-polar.jpg
Worked hard to get this to render on chart.
used
-60
28

-20
28

Set Coord 1 toward the pole, on -60 lat, Set coord 2 directly above on -20 lat

Hit Get Mapping. Took picture.
Hit Apply, Took Picture
Then would hit reset and go through it again.

Finally when it became clear no matter what I did it would not render with straight lines, I hit "Finish" to see what would happen.

Bitmap.cpp [802] assert error again.

Note: I do think things are working better, the computer is not working as hard and pausing, etc. Failures are not as immediate and the computer is not freezing as it was before, where I had to go into task manager and simply shutdown opnecpn task and then under processes do the same thing.

Maybe I'll get one that works this next one!

[rgleason]

Using 00_UKMet_Boden+00-Polar.gif
Pick Polar
Coord 1 70
-35
Coord 2 20
-35
Get Mapping take screenshot
Apply - resulting image has neg dimensions.
Then bipmap.cpp [802]


Can't seem to find a polar that works. Do you have one I should try?
These polars were all done with OpenGL OFF
