[OSM-talk] New mappaint version 5024 - now with a "fill area opacity" preference

[Ulf Lamping]

Hi List!

After some user demand to set the transparency of filled areas, I've 
just committed a new mappaint version 5024.

It now has an integer preference "mappaint.fillalpha" to set the opacity 
level that is used to fill areas. It can be set between 0 (transparent - 
"0 is invisible") and 255 (solid - as before). The default is 50, which 
seems to be the best possible compromise between "visibility" (you can 
see something "is" there) and "transparency" (see something "behind" 
it), but I'm very certain that a lot of people will prefer other values 
here :-)

There is a drawback with this setting: areas are now much darker than 
their surrounding way, I guess because the background is now "shining 
through", which is black (or at least dark for WMS images).

You can change the setting while JOSM is running and it should 
immediately take effect (you might need to slightly zoom or move the 
drawing area).

I've updated 
http://wiki.openstreetmap.org/index.php/JOSM/Plugins/MapPaint and 
http://josm.openstreetmap.de/wiki/Plugins accordingly.


Please try out and comment.

P.S: I know, it's becoming more and more pressing that we need some 
comfortable GUI way to change these mappaint settings
P.P.S: No, I didn't had the time to look at the "switch mappaint on/off 
completely" that was also discussed / demanded
