WeatherFax ...

[rgleason]

MS VC Debugger failed, but I got this screen shot. The errors are listed with line number

weatherfax_pi.dll!WeatherFaxImage::RenderImage(wxD C & dc, PlugIn_ViewPort * vp) Line 494 + 0x34 bytes C++

weatherfax_pi.dll!weatherfax_pi::RenderOverlay(wxD C & dc, PlugIn_ViewPort * vp) Line 227 C++



Also if you don't hit Apply I think there is an error.

Have you had any issues with the plugin since the update?

I think this happens if you put in invalid image coordinates and are not using opengl a case I probably forgot to test. I should be able to correct this.

Could you try with opengl enabled. Also, try with valid image coordinates. True ratio should be 1 in most cases, but if the input polar image is stretched it could be different. If it is -1 or negative at all, then you have done something wrong.

Also, are there any other crashes or assert failures?

This was for a polar with Australia. I believe I got the basic coords and lat long close. When "Applied" the fax is rendered with straight lines. When "Finish" it bombs.

bitmapimage.cpp 802 (I think that was the line in the popup message, I could not get a screenshot.)

only have
> wxbase28ud_vc_custom.dll!wxTrap() Line 678 C++
in call stack.

It failed very fast.

Here are the images (same file as above) tried again. -Both without OpenGL

[rgleason]

Ok, this morning do it again.
1. No opengl
2. Same file IDY00030.201302181800-Polar.png as attached above after inspecting with Gimp
3. Entered the following coords and guidelines -see screen shot.

292 -40
368 -130
292 -10
4 -130
After apply and processed - see screen shot.
412 -40
293 -130
412 -10
38 -130
Hit finish and instant fault - see screen shot.

...\..\src\tnsw\bitmap.cpp(802): assert "image.Ok() failed in wxbitmap::wxBitImage::CreatefromImage(): invalid range.

4. The only call stack item is
> wxbase28ud_vc_custom.dll!wxTrap() Line 678 C++
There are no non-widget items in the call stack that I can find.
5. I've included a screen shot of MS VC++ below.

Ok Sean, you'll like the next series using the same Australian polar file. The first part is with OPENGL checked.
I noticed that with OpenGL checked different lat long settings are required, why? Shouldn''t they be the same? The latitudes have to be foreshortened or the blue circle diameters are too short and do not align with latitudes. Note the differences in what Lat Long is entered. With opengl on, the polar fax is not rendered, but the program does not crash, and you can go back and edit the fax, and adjust the coords and lat/long. I did that several times and tried to get the fax to render on the chart.

[rgleason]

Okay, it did not fail. So still using OpenGL I went back to Edit and tried adjusting more. Making straightlines (used the same settting that were used for no Opengl and those did not produce straightlines). When finishing it did not fail but image did not appear. Sliders and invert check are a little reluctant to work.

[rgleason]

Then I went back in and did some more adjustments to match up the blue rings with latitudes. (This does not look like the rings are right. I must have the sequence of this process wrong) It did not bomb and I could go to edit again.

- Anyway the lat settings required to align the blue rings are different (shorter -40 and -20 ) than when it is not using OpenGL!! Why is that I wonder???

[rgleason]

Okay I've sort of forgotten the next screens, these are without OpenGL on (I just turned it off in the Debug version 3.2 and continued. In this case it bombed again with the same codes as before.

I had to change the lat settings I believe (Ok this is where I had to adjust to lat to be -40 and -20, rather than -10) anyway the values are shown in the images. It failed wwith the same error.

[rgleason]

Mercator, with OpenGL, Maritius mercator

(Hint: on images, hoover over image and see the title of the image which helps explain. -Also above.)

First set coords
with Upper Red coords set on lower right corner (because that is towards south pole?)
and Lower Blue coords set on upper left corner.
Entered coords as I thought they should be and Finished.
Image was stretched.

Then reversed the Coords
Upper Red coords set on upper left
Lower Blue coords set on lower right
Also changed the lat/longs.
Finished and still stretched.

Then reversed the longitudes and Finished.
The image was not stretched, but I am not sure if it was in the correct location.

When working with southern mercators it is confusing.
How do we apply the tools to get it right?

I would like to have some color on the right menu
(Coord #1 Values on top - Red)
(Coord #2 Values on bot - Blue)

Okay I made a stupid error. EAST is PLUS!
See the last screenshot

Maybe have some reminder, or is this too rudimentary?

East of Greenwich is +
West of Greenwich is -
North of Equator is +
South of Equator is -

Mercator projections can we pick
Coord 1=red = upper left
Coord 2=blue= lower right
for both North and South Hemispheres?
Looks like yes. Maybe we should say so?

[rgleason]

Polar Projections Suggestion:
Have the Red coordinates show a Red Arrow in the direction of the Pole!!!!
with a note that the red arrow has to point in the direction of the pole (north or south)

Sorry, you have the note for
N+, S-, E+, W-

[rgleason]

Suggestion.
Keep left margin coords and lat-long
Identify them with appropriate color (red & blue)
After coords are selected possibly have
these colored arrows appear in the right margin
alongside the image.

^ [red arrow up]
v [red arrow dn]

[IMAGE OF FAX HERE]

^ [blue arrow up]
v [blue arrow dn]

< > [red arrows] < > [blue arrows]
In small area under image, colored arrowsappear after
coords are picked.

[rgleason]

Maybe the red & blue arrows that appear on the margin should be on the left side, so scroll appears on the right side.

Also it looks like you may be planning on putting the Coord Mapping Correction in the left margin under Coords setting... sort of like this?
