Those interested in testing this new functionality on Windows, download the attached file, remove the .doc extension and copy to the plugins folder in your OpenCPN installation.
OpenCPN 3.1.x needed.
I patched the code to build successfully, so all the functionality should be there.

Win 7 SP1 (64bit)
OpenCPN 3.1.1328
I enabled the plug in with the default preferences.
Selected new fax file (chose a fax from Boston that was stored as a tiff)
when I set the coordinates there was no mark on the fax to show where I had set the coordinates.
After selecting OK the fax was not visible, I could not change the scale or move the OpenCPN chart.
Deleting the fax from the popup window had no effect and I had to shut down OpenCPN to reset it.

So, once you entered the coordinates and selected ok, it basically locked up opencpn.
The image remained in the list of the popup window, or opencpn remained locked up?

Are you using opengl mode (in settings) ?

[LJH]

Yes,
I have the Use Accelerated Graphics (OpenGL) selected.

Dear boat alexandra,

Downloaded the dll and used it in Opencpn 3.1.1405, OS is Win7. Click on Weatherfax image, popup, select New, browse to fax folder, select fax, New Window pops up which is independent and can be maximized, set two lat long points fine. Pick "OK", Fax window drops leaving the first popup, but nothing happens to the Opencpn chart screen. Can still move transparency and highlight the file name of the fax and hit Edit and set the two points again, but there is something wrong because when I drag the first popup window with "new, edit, delete" it duplicates, and if I have another program up (browser, email etc) the Opencpn Chart window starts showing a portion of that program where the chart is supposed to be. I've done this with OpenGL on and off.

The path name for fax folder was not accepted which may give you a clue.
Is there a way to run the plugin in debug mode? I could try that.

I used Pavel's dll let me know when I should update by "git" please.
Notice you have a Bristol 27 all the way over in New Zealand! Great boat, great country.

Can you try without opengl. Also. Is there any way possible you can use the debugger and find which line of code it has locked up on?

Deleted opencpn-git/plugins/weatherfax_pi directory

In Cmd prompt went to opencpn-git/plugins directory

Executed git clone git://github.com/seandepagnier/weatherfax_pi.git ---100%

Then cd .. up to opencpn-git directory

Then cd build down into opencpn-git/build directory

Then cmake .. which executes ***building weatherfax_pi writing spec, config done, generating done, build files have been written to opnecpn-git/build and
under opencpn-git/build/plugins we find a new weatherfax_pi directory.

Then cmake[space]--build[space].[period]
Lots of messages while compiling

Ran MS VC++ 2010 Express and with Release and Win32 selected
picked Debug > Build

See output files attached.

C:\Data-Dart...Navigation\opencpn-git\build\plugins\weatherfax_pi\Release
still has old weatherfax_pi.dll dated from yesterday, so it did not complete.

Don't know how to configure a plugin to run in Debug mode, would like some instructions, but first I think we need to compile it. Should I comment out libaudio in cmake to start?

Also please do upload or send an audio file I will try it.

Pavel, intended to thank you for your assistance to Sean earlier.

Using W7
Opengl: I only get the weatherfax pic (.tif downloaded with Airmail/viewfax) when selecting 'inverted'
Legacy display: fine without inverting
(see pics)

Request: being able to specify a lat/long template instead of using the calibrating procedure.

Re: UK weatherfaxes (downloaded with i.e. Airmail/viewfax) They use a polar stereographic projection, and I have little hope they can be displayed with OpenCpn.

Many thanks, Pavel...

sailor54 What version of Opencpn? Did you use Pavel's dll?
How did you get it working? Mine hangs up using Pavel's dll and when I compile new git version with all libaudio it does not yet finish compiling. Some more specifics would be helpful.

I've been trying gif files. Maybe I should be trying tiff etc.

Kubuntu 64 bit 12.10
I compiled my own. No problems.
All proceeds well until it's time to actually display the fax. This is what I get.

I tried to turn of OpenGL. not surprisingly the app crashed.

Thank you sailor54. Downloaded pwam99.tif put in FaxWx directory.
In OpenCpn 3.1.1405 using weatherfax_pi.dll plugin compiled by Pavel.
Was able to open Weatherfax icon, browse to FaxWx directory, could not see tiff file until I selected "all files". Might want to add "*.tiff" to supported image files. Then changed file to "*.tif" and it shows up under suppported image files.

Set Coordinates view. Picked "Set Coordinates" Hit ok.
Picked 30n 90w enter 30 then -90
Picked 60n 0 enter 60 then 0
Then OK fax coord entry window goes away
Leaves Weather Fax popup window showing the file highlighted.
Now the Opencpn chart area screen is getting corrupted by other stuff.
I close the Weather Fax popup and it goes away, the fax does not come up in Opencpn which I think is supposed to happen, and the corruption of the chart window continues. I havve to shut down Opencpn now.

Here is a view of Opencpn

I've turned off OpenGL and also have tried it when on.

I cloned Nohal's weatherfax_pi.git with his windows fixes. With one small change it compiled and ran OK. PCM.cpp lines 42,43,44,45 change "isnan" to "_isnan".

1. Testing with noaa gifs, a large file will cause an error at weatherfax_pi.cpp line 246. If the file is cropped to about 1200X750 it works fine.

2. Using OpenGL I also noted that the image must be inverted to display.

This project has really begun well. Thanks.
