I would like to propose for testing new grib features .
I am sorry this could be redundant as another version is being developed
but I did know when I started ;
It"s not a new plugin but only an evolution of the current
- At the start , you need to set the preferences : In addition to the usual , you will be able to choose the time format and the possibility to complete some missing grib records ( this functionality is the same as in Zygrib)
-Clicking on the grib icon will display the panel and the data of the youngest file found in the memorized grib folder and the nearest forecast
from "now" will automatically be selected.
In the display and control panel
(shot1) you will find a drop-down list and six buttons in the first top line . The drop-down list shows the forecast
time you can choose . The first and second buttons are previous and next forecast .
The third button allow to re-select directly the nearest forecast from "now" (the one selected at the start)
The next open the memorized file directory to open a new file . If you select a file in another folder , this new path will be memorized . If you want to select a folder where there is no file , type any name . You will have "Empty directory" message but the path will be memorized.
The next button (with a small red heart) open the data selection panel (shot grib2). there are 2 parts
: -data shown in the numeric panel - graphical data shown ( wind
barbs , isobars lines and you can choose one of the coloured maps available)
In the numeric panel , data are displayed by lines of three . thus if you select, for example, four data , only two lines will be displayed .Only nine data can be displayed at a time (three lines). As there are ten possibilities , the last one , if ten are selected , will be hide.
The last button to the right allow to prepare an eMail
To use this fonctionnality , it is better to know Saildocs or to visit the site at Home Page
clicking on this button will display the request profile memorized ( shot grib3 ). You can accept (send) or modify . In this case a request selection panel will be displayed to select what you want (shot grib4) .
Note : This is a very simplified function : The plugin do not really send an email
, but open your local email system with an email prepared . You have just to click "send" . Be careful : You must have a valid email environnement on your PC and it must be set as the default email system
The zone selected will be the one you see on your screen
(rounded at the degree above ) Be careful , a large zone will increase dramaticaly the file size !
To test you can replace the grib_pi.dll file in OpenCPN/plugins by the one attached ( rename it to suppress .doc)

To compile its ,as I used the MAPI function of wxWidgets, you will need to copy the entire folder "net" from
