Created attachment 4601 newer icon for icons/liquid/(some of icon)-1.png as we know, there are some liquid theme icon, not matched between name and image. In simple example, when program shows rain and rain shower on the same window, rain is ok. but rain shower seems not ok. because the number of water drop in rain shower icon is less than rain icon. so I made some improved icon for suggestion. but I don't know whether I drew forecasting image exactly or not. so, to apply my suggestion into the main tree, we need double check my suggestion is better or not. original image isn't modified, because my image can be wrong to show. instead I've added "-1" between name and extension for each modified file. I'll give one zip file contains my suggestion. Thank you.
You're absolutely right, the names and icons do not match! That's really a very nice improvement, good work! The icons are all fine, except I do not agree with your definition of "Rainshower". After doing some search, I found the following definition on http://www.theweathernetwork.com/weathericons/?product=weathericons&pagecontent=index: "Showers – Some sun is expected, interspersed with showers from time to time. As opposed to rain, showers describe liquid precipitation that can vary greatly in intensity over a short amount of time. A forecast for showers indicates a higher likelihood of seeing precipitation than a forecast for scattered or isolated showers. Precipitation may be locally heavy for short amounts of time." However, what I concluded after looking all the symbols and descriptions is that the interpretation of some symbols is not exact, wrong or at least unclear, and I need to investigate and elaborate on that. For example, LIGHTRAIN should not be "rain showers", but "constant light rain". RAIN apparently is "constant rain", and LIGHTRAINSUN could be interpreted as "Rain showers". Since I have started development on the plugin, I have not thought about the translations and took their correctness as granted. Documentation available from met.no is a bit sparse. This page http://www.mir-co.net/sonstiges/wetterausdruecke.htm unfortunately is in german, but it contains symbol <-> description translations in the exact order as on http://api.met.no/weatherapi/weathericon/1.0/documentation. That can't be coincidence! While some may be missing (ID > 19), they make sense and I strongly believe they are correct and will try to translate them to English. But maybe other people are better at that, and given the Norwegian terms and a good dictionary, they can resolve this. I will think more about this and then send a mail to the mailing list. There's also the met.no / yr.no website that I can look at and make comparisons. Thank you for bringing this to my attention, and of course for updating the icons, they will be included in the upcoming release 0.8.2. Due to the above considerations, the release will likely be postponed a bit.
I've committed the updated icons to git: http://git.xfce.org/panel-plugins/xfce4-weather-plugin/commit/?id=33bbf186ed38bd8a210ca76b10ab9af0c7b0f499 Thanks again for your contribution.
