Hi Nick, my understanding is that you always have another water polygon, either ocean or natural=water.

Hi,
thanks for the help. I see two ways to handle the a polygon with natural=bay: 1) in ponts style with natural=bay & name=* [....] 2) in polygons (as it is now) with natural=bay [0x3d resolution 18]
In case of 1) we just need option add-pois-to-areas In case of 2) we would want to render the water area covered by the bay polygon different, but not anything on the land or on islands. Would that be possible?
Gerd

Andrzej is correct about how transparency is defined
Garmin regards all polygons with transparency as bitmaps and therefore require 2 colours.
The Bitmap need to be shown below the xpm
If a polygon is completely transparent then a second 'dummy' colour is still needed
Xpm="32 32 2 1" "0 c none" "1 c #C8C8C8" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" "00000000000000000000000000000000" ;12345678901234567890123456789012 [end]

Hi Gerd,
I use TypViewer for creating typ files and I don't know XPM details. But looking at TypViewer output, I guess that transparent pixels are defined with color like that:
" c none"
where space ' ' is used for marking pixels.
Changing draw order instead of transparent graphics could be a solution too, but I'm not sure if covered polygon label would remain visible. And without label, there is not much use of this object.
