Perhaps I can help here. There are three versions of ImageSalsa, all of them ARE standalone and each offers more levels of complexity. The largest version can retrieve weather data from VWS, but I think Brian said some time ago that he could duplicate the file format it uses so you could use WD to provide the data IF he can do this AND wants to!
Rupp, the images on the demo page are created from within ImageSalsa, they are simply jpegs that the program has composed not dynamic html.
Here’s another idea of how it can be used. In the UK we are very limited on the availability of rain radar images. So what I wanted was my own composite image of cloud cover with rain radar superimposed on top of it. This isn’t available as far as I know from any site, so this is how I did it.
I took this basic image and cropped and resized it on level0 of WeatherVision. This would be my base background.
I then grabbed this cloud cover image and removed the blue bits with transparency. I don’t like the fact that the thicker cloud is whiter in this image so I used WeatherVision to invert the grayscale so these thicker clouds became dark and the thinner ones light. Then I added this image over the base image making the clear air transparent.
Then I grabbed the rain radar image that is available to us Brits.
This is quite a complex image as far as colours are concerned but once more using the multiple colour transparencies available in WeatherVision, I removed the sea, the logo, the land etc leaving me with just the rain radar data.
This image was then added over the cloud image, a few text objects added to give some information and there it is!
The program does this automatically every 10 minutes and that is the magic of it, totally dynamic! The whole process to set this up took about 15 minutes and I’m sure with a little more time it could be improved upon but at least it shows what can be done.
Does that help explain a bit more about what it can do? As you see, there is not a sign of VWS in there
