boat_alexandra that would be WONDERFUL.
1. I use Win7 can compile and test Opencpn and plugins, but I don't have an SSB. However a friend does and it will be available after the covers come off this spring. Will that be too late? I'd like to help.
2. qtVlm allows us to select the location by browsing the file structure. You can see the directory in the link below. Once a given fax series is setup, those settings can remain. qtVlm has a number of setups that can be used to save the settings.
I'll tell you how the Routing Software
qtVlm locates and scales the weather fax, at first it was a little awkward, but it was actually self explanatory and quite easy.
First take a look at this snapshot with the input area to locate and scale the fax in qtVlm
I can attach some other shots of the process.
In qtVlm you select
Gribfile > Open Fax Meteo
(or Close Fax Meteo)
A window pops up if you select Open Fax Meteo
The popup contains:
"Fax file's name
" with "Browse
"Left corner position
North/South dropdown, Degree selection, decimal minutes
West/East dropdown, Degree selection, decimal minutes
: 120 degrees for example
50 degrees for example
qtVlm has 4 selections for setups. It would probably be good to have a few more.
There is a note: Yoou can also use the mouse to move (SHIFT key), to resize (CTRL key), or to tuen opacity (ALT key)
3. wxWidgets does not support recording audio. What library should be used? Is it ok to only support reading wav files from disk at least at first?
--Ok this is about the source weatherfax file. I think you must be referring to Navtex weather fax and that must be a wav file which is picked up via SSB.
nohal or Dave or one of the other great programmers for OpenCpn will be able to help us with this question. (no disrespect for your skills intended!!!) --Grib file pluggin..wmm plugins. h'mm! -So much to learn for me.
What I did while using qtVlm from the desk with internet
was simply download the weather fax off Noaa's website selecting the "product" desired. Ocean Prediction Center - Product Loops
